Wiring harnesses for the Moto Guzzi 850 T4

Main harness for the 850 T4

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.

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

At the alternator: Original additional/special sheathing (MG# 14710200) exiting the alternator cover is not included because it does not accept the larger diameter heat resistant wire; regular sheathing is used instead and it fits nicely through the alternator cover.

Distributor to main harness - left side

Connects the ignition points inside the distributor to the main harness (further connects to the negative terminal on the coil serving the left cylinder). A ring terminal is used for a more secure fitment inside the distributor. The green wire exits the distributor toward the rear of the motorcycle.

Distributor to main harness - right side

Connects the ignition points inside the distributor to the main harness (further connects to the negative terminal on the coil serving the right cylinder). A ring terminal is used for a more secure fitment inside the distributor. The red wire exits the distributor toward the front of the motorcycle.

Tail light harness applicable to several tail lights: MG# 10740900 MG# 12740900 MG# 12740920 MG# 14474900

A simple harness to replace the aging wires at your tail light. Includes longer springs to replace the originals. Once the wires are fit to the tail light, crimp the included female bullet terminals in place.

Domino left handlebar switch

Excellent quality modern style left handlebar switch providing standard expected functionality that falls easily to hand. Pairs very nicely with the Domino right handlebar switch. Genuine Domino brand. Made in Italy. Sold each.

Should you wish, I will happily modify the switch's wiring to work with your specific Moto Guzzi; making the switch plug-in ready. Contact me for details and pricing.

Specifications:

• Handlebar fitment: 22 mm or ⁷⁄₈ inch diameter
• Lights selector: lights off, running lights on, headlight and running lights on
• Beam selector: low beam, high beam
• Index finger trigger: flashes the high beam (using positive current)
• Horn button: beeps the horn (using positve current)
• Turn signals: left side, right side, push to end

I chose to sell this switch because of its outstanding quality, functionality, size, and appearance (this is not a cheaply made product). I use this switch on my personal V1000 I-Convert and V1000 G5 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 and horn circuits. I have an excellent relay solution available for purchase.

Push-pull switch

Good quality switch with screw-type terminals. 25 amp capacity. 8 mm × 1 mm threads. Knob unscrews for fitment. Sold each.

Bracket for push-pull switch

This bracket is identical to the starter button bracket, except the hole is ~8 mm in diameter. The intent is to mount this bracket on the left clutch perch, mirroring the starter button bracket. Then, a push-pull switch may be fit to the bracket and used to conveniently actuate spot lights or other electrical components. Stainless steel. Very nice. Push-pull switch sold separately. Sold each.

Toggle switch

Excellent quality SEALED switch with six quick connect terminals (as original). 15 amp capacity, on-on double pole double throw, comes complete with mounting hardware (as shown). Sold each.
