Wiring harnesses for the Moto Guzzi 750 S

Main harness for the 750 S

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.

NOTE: The official Moto Guzzi 750 S spare parts catalog lists MG# 14747110 as the part number for the 750 S main harness. The one I sell here is a duplicate of the main harness used by the V7 Sport. I am not aware of the differences between MG# 14747100 and MG# 14747110. I believe the V7 Sport main harness will work perfectly on the 750 S. If you know otherwise or have any trouble after purchase, I will work with you to correct any issues.

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

Right handlebar switch

Ready to solder to your switch. Works with switch pictured below (not included).

NOTE: The official Moto Guzzi 750 S spare parts catalog lists MG# 12750301 as the part number for this 750 S sub-harness. The one I sell here is a duplicate of the sub-harness used by the V7 Sport. I am not aware of the differences between MG# 12750300 and MG# 12750301. I believe the V7 Sport sub-harness will work perfectly on the 750 S. If you know otherwise or have any trouble after purchase, I will work with you to correct any issues.

IMPORTANT NOTE: It is very easy to destroy original or aftermarket switches when using a conventional soldering iron. Even if you know exactly what you are doing and are very experienced with soldering procedures, the switches can very easily be rendered useless. Rather than using solder, I strongly recommend the following:

• Use a conductive epoxy to secure the wires to the switch. Most epoxies, including JB Weld, do not conduct electricity. MG Chemicals makes a conductive epoxy that I've used with excellent results (part number 8331D). Atom Adehesives AA-PROD 123 is a less expensive epoxy that Charlie Mullendore of Antietam Classic Cycle reports works well. Nick Rossi contacted Atom Adhesives directly and found that AA-Duct 902 is the most conductive epoxy and that AA-Duct 916 is more suitable for motorcycle applications as it is flexible once cured and will be more resistant to vibration. Nick prefers the AA-Duct 916 (available from Amazon).

Extension cable for right front turn signal

Distributor to coil - left side

Connects the ignition points inside the distributor directly to 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 coil - right side

Connects the ignition points inside the distributor directly to 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.

Ignition switch

NOTE: This sub-harness is used on the V7 Sport and its ignition switch. The official Moto Guzzi 750 S spare parts catalog does not list this sub-harness. You may or may not require this sub-harness, depending on which ignition switch you have. If your ignition switch has integrated wiring, then you will need this sub-harness.

Alternator harness

Uses all of the original correct original colors and heat resistant materials. Connections at alternator and rectifier are correct and accurate for the 750 S: lacking the flat 3-connection plug that was fit to later models.

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.

Installation instructions

Alternator harness

This alternate version uses normal automotive wire that is less heat resistant (as original). This yields a smaller diameter bundle of wires that may be fit through the original rubber sheathing. Terminals are intentionally left off of one end of the harness so that the wires may be routed through the original rubber sheathing.

SELECT THIS VERSION ONLY IF YOU ARE PLANNING TO RE-USE OR REPLACE YOUR ORIGINAL RUBBER SHEATHING.

Uses all of the original correct original colors. Connections at alternator and rectifier are correct and accurate for the 750 S: lacking the flat 3-connection plug that was fit to later models.

Crimp connections after routing the harness through your original rubber sheathing:

• Yellow: straight 6.3 mm female spade terminal
• Orange: straight 6.3 mm female spade terminal
• Green: straight 6.3 mm female spade terminal
• Brown: straight 6.3 mm female spade terminal
• Black: flag 6.3 mm female spade terminal

Multifunction handlebar switch pre-wired for Moto Guzzi 750 S 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 (⁷⁄₈ 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 750 S models. 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 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.
