Main harness for the Le Mans

Part Number Description Photo Price
MG# 14747150

Main harness for the Le Mans (Series 1)

This harness fits the first series of the original Le Mans that used the same tail light as the 750 S3. It does not fit the Le Mans II, Le Mans CX 100, Le Mans III, or Le Mans 1000.

I duplicated an original main harness. In construction, I use the same gauge of wire, the same colors and tracers (stripes), the same length and sheathing, the same terminals, etc. All terminals are of the double crimp, strain relief variety.

The wires routed to the alternator are constructed of heat resistant materials.

The original Le Mans harness used an insufficient gauge of wire to actuate the starter solenoid circuit. I have chosen to use thicker wire for the two wires involved in this circuit. Should you wish to use the original, thinner gauge of wire, please let me know.

  • Note: Main harnesses comprise the main - or primary - wiring harness. Each motorcycle also uses ancillary sub-harnesses. The individual sub-harnesses are sold separately.

SWITCH-TONTI

Multifunction handlebar switch pre-wired for Moto Guzzi Tonti models

After 10 years of building Moto Guzzi harnesses and supporting my customers, I have learned that people experience the most frustration and challenges when attempting to wire the left handlebar switch (by far). To help alleviate these issues, I am now offering this brand new switch with period appearance. The switch features a metal body and fits 22 mm (78 inch) handlebars. It is pre-wired so that you can mount it on your handlebar and plug in the wires quickly and easily.

I chose this switch because of its functionality, size, and appearance. While it does not boast all of the features and functions of a modern switch, it is a good basic switch that is appropriate to the Tonti frames. I use a switch like this on my personal Ambassador and I find it easy to use and my thumb operates all of the controls with ease. As with all handlebar switches, I strongly recommend the use of relays for the headlight circuit. I have an excellent relay solution available for purchase.

  • Has a true off position where both the running lights and headlight are off.
  • Headlight switch has the standard low beam and high beam selector.
  • Turn signal switch functions as you would expect: move the switch left to actuate the left turn signals; move the switch right to actuate the right turn signals; move the switch to the middle position to turn off turn signals.
  • Simple push-button horn.
  • Can be fit between the handlebar grip and the clutch perch (this is my recommended location for ease of use).

RELAY-HARNESS-TONTI

Relay solution for the horns, coils, headlight high beam, and headlight low beam

No more excuses! Relays greatly improve the performance of the horns, coils, and headlight. Your horns will be louder, your coils will get all the amperage they require, and your headlights will burn brighter when you use relays. Relays also dramatically extend the life of your handlebar switches.

This relay kit is a well thought-out and solid solution that is in line with what I believe Lino Tonti might have designed. A few points I'll mention:

  • Complete solution - includes all needed components.
  • Works with your original wiring harness.
  • The bank of four relay sockets is intended to be mounted between the battery and the rear plastic inner fender. This affords ease of installation as well as later access. This keeps the headlight bucket largely uncluttered and doesn't hide anything under the gas tank were it is difficult to access.
  • Wiring is color coded to original specifications.
  • Relay sockets are used to make installation easy and trouble free.
  • Each relay is wired independently from each other: horns, coils, headlight high beam, and headlight low beam. This slight redundancy permits one relay to fail without affecting the functionality of any other relay.
  • Includes all four needed relays.
  • Relays are of a standard size and easily replaced at any time (they simply plug into the socket).
  • Simple installation - See installation instructions.

KS-TO-MOLEX

Easy plug in solution for connecting K&S switches on Tonti models originally equipped with Molex plugs.

K&S makes a variety of good quality, affordable handlebar switches that are popular replacements for the original switch gear. The K&S 12-0030 is one popular model.

No more need to fiddle with butt connectors, soldering, or heat shrink. Just plug the 9-pin connector into the plug that came with your K&S switch, and the other end into the 12-pin connector on the back of your headlight shell. Made specifically to support the 850 T, 850 T3, V1000 I-Convert, V1000 G5, 1000 SP, Le Mans, Le Mans III, and other such models. If in doubt as to whether it will work with your model, just ask. I am happy to build to suit your Guzzi.

Please note: Some original handlebar switches were grounded through the handlebar. Other original switches were grounded through the Molex 12-pin connector. If needed for your application, a separate ground wire will be provided for use inside the headlight shell. Simply fit it in position 3 of the 12-pin Molex plug inside the headlight shell (position 1 has a red/black wire).

LE-MANS-SWITCH-SPLITTER-MOLEX-GUZZI

Easy plug in solution for connecting later model Moto Guzzi switches to the Le Mans.

Later Moto Guzzi switches are much easier to find than the original switches fit to the Le Mans. This splitter provides a plug-in solution to easily connect later Guzzi switches to the original Le Mans single 15-pin connector. Originally, the wires from both the left and right handlebar switches shared a single 15-pin Molex connector. This splitter splits the connections into two separate plugs: one each for the left and right handlebar switches. This makes connecting switches MUCH easier and also makes it much simpler to remove a single switch, etc. Made specifically to support the 850 Le Mans. I am happy to build to suit your Guzzi.

The splitter is approximately 100 mm (~4 inch) in length. If you need it to be longer, please let me know.

DOMINO-HORN-RELAY-WIRES

Relay and needed wiring to operate the horns using positive current (instead of the original Guzzi handlebar switch that provided the ground for the horns).

The Domino handlebar switch actuates the horns using positive current whereas the original Guzzi switch actuated the horn by providing a ground. This sub-harness replaces the relay under the fuel tank with a new relay and provides the necessary wiring to actuate the horns.

Installation instructions:

  1. Remove the fuel tank to gain access to the wiring.
  2. Disconnect the existing black and brown wires from the horns.
  3. Connect the existing black wire that you just disconnected to terminal 86 on the new relay.
  4. Connect the new black and brown wires to the horns.
  5. Connect both black wires with ring terminals to ground.
  6. Locate the existing relay under the fuel tank. Disconnect the group of three wires (brown, brown, and blue) from the existing relay. Connect these three wires to terminal 30 on the new relay.

MOLEX-TO-MOLEX-RIGHT

Easy plug in solution for connecting aftermarket right-side handlebar switches on Tonti models originally equipped with Molex plugs.

Aftermarket switches sometimes use Molex plugs. Generally, the plugs used do not match the Guzzi size or pin configuration. Tomaselli and Domino switches sometimes fall into this category.

No more need to fiddle with butt connectors, soldering, or heat shrink. Just plug the Molex connector into the plug that came with your aftermarket switch, and the other end into the 12-pin connector on the back of your headlight shell. Made specifically to support the 850 T, 850 T3, V1000 I-Convert, V1000 G5, 1000 SP, Le Mans, Le Mans III, and other such models. If in doubt as to whether it will work with your model, just ask. I am happy to build to suit your Guzzi.

Please note: Some original handlebar switches were grounded through the handlebar. Other original switches were grounded through the Molex 4-pin connector. A separate ground wire is provided if needed for your application.

When ordering: Please specify the aftermarket switch you are using and the total length needed.

HANDLEBAR-LEFT-12-UNIVERSAL

Wiring for universal left handlebar switches (headlight, parking lights, horn, turn signals)

Works great with the multitude of universal switches available. Butt connectors and heat shrink are included to splice the sub-harness directly to the wires from the switch. Wire connections should be staggered to yield a smaller overall finished diameter. Larger diameter sheathing is provided to aid routing the spliced wires through the sheathing after all of the connections have been made. Wires to the headlight plug are 800 mm in length. Wire to ground is 1000 mm in length. Wires are intentionally left separate from the 12 terminal plug - so that the wires may be more easily spliced and routed through the sheathing or inside the handlebar.

  • IMPORTANT NOTE: As with all switches actuating higher amperage components, I consider a relay for the headlight and horns a good idea.

Plug information:

  • Position 1: red/black (power in for headlights)
  • Position 2: empty
  • Position 3: empty
  • Position 4: red (power in for parking lights - almost never needed with non-original switches)
  • Position 5: green (power out to headlight low beam)
  • Position 6: brown (power out to headlight high beam)
  • Position 7: yellow (power out to parking lights)
  • Position 8: green/black (power out to left turn signals)
  • Position 9: pink (power out to right turn signals)
  • Position 10: gray (ground for headlight high beam flash relay - almost never needed with non-original switches)

HANDLEBAR-RIGHT-4-UNIVERSAL

Wiring for universal right handlebar switches (starter button and kill switch)

Works great with the K&S 12-0203 available from an online retailer such as MG Cycle (would also work equally well with many other generic switches). Butt connectors and heat shrink are included to splice the sub-harness directly to the wires from the switch. Wire connections should be staggered to yield a smaller overall finished diameter. Larger diameter sheathing is provided to aid routing the spliced wires through the sheathing after all of the connections have been made. Wires to the headlight plug are 800 mm in length. Wires are intentionally left separate from the 4 terminal plug - so that the wires may be more easily spliced and routed through the sheathing or inside the handlebar.

  • IMPORTANT NOTE: As with all switches actuating higher amperage components, I consider a relay for the coils a good idea and a relay for the starter a necessity.

Plug information:

  • Position 1: white/black (starter button / ground out to starter relay)
  • Position 2: white (kill switch / power out to coils)
  • Position 3: white (kill switch / power in for coils)
