Hey guys, im chasing down a cruise control issue and noticed this harness above the clutch was left unplugged. Im assuming it attaches to the switch assembly, (Part# 36760-SE0-003). Im curious, is this the wiring done from factory?

 

Clutch has two switches.

Interlock for engine start

Interlock for Cruise Control

Engine start is the one where switch action occurs when clutch fully pressed.

CC is the one where switch action occurs as soon as you begin to press pedal.

Common failure points for both are the little plastic stopper that presses switch plunger. Brittle, breaks, falls out.

Common mods are engine start interlock bypass. Ability to start engine wo pressing clutch. Involves some sort of bridge between wires in interlock connector.

Sometimes down with jumper wire, paper clip, etc. Sometimes done into back of connector (connector typically left plugged into switch, but not necessarily), sometimes into front of connector (connector has to be unplugged for wire to access).

Sometimes down with another switch, rather than simple jumper. An aux switch added somewhere, repurpose another unused switch on dash, etc. I did mine via a relay and brake pedal switch.

When done w switch, connector might be left plugged in (can start either using other switch, or using clutch pedal), or unplugged (can only start using other switch, clutch pedal has no effect).

So is this the switch for clutch fully pressed,or initially pressed?

Is there any additional wires connected to unplugged harness?

 

I'm not entirely sure if it is for fully or initially pressed. Just realizing it didn't attach my photos for whatever reason, let me fix that and thank you for the reply.

 

Red wiring splices ain't factory. A former owner has buggered some of the wiring presumably to bypass the requirement to have the clutch depressed to crank the engine. This wiring to makes the starting circuit think the clutch is disengaged but cruise control will only work if the clutch is engaged.

Haha, I didn't think so but also idk anything. Wish i could talk to the previous owner sooo bad. Any reason i should not plug it in and see if that fixes my cruise control issue? Thank you for the input Chuck!

 

Do a forum search for "clutch bypass" or similar. This modification has been around for decades. Reverse engineer it. The wiring diagrams are here.

Check this thread for clues as well.

Streets here are totally ice covered so I can't confirm today but cruise disengages if the brake or clutch are depressed. Won't go back into cruise when the clutch is re-engaged like when changing gears. Gotta hit the steering wheel switch again.

This will be very helpful. Thank you!

 

Yeah, just looking at it, you'll be able to tell of swotch action occurs when clutch initially pressed, or when fully pressed. If its cc or engine start interlock switch.

Like literally just get under there, look, press pedal, think. Is this switch doing anything when I first press, or only when I fully press? Its literally just looking and thinking.

One is way easier to see than other. So just look at one that is easier to see.
