manual transmission harness

[bpm4x4]

88 Peugeot tranny behind a 4.0

 

there is a 4 wire harness connector 2 wires are for the backup light, but what are the other 2 for? One has low voltage on it, and I think the other is grounded, why are they hooked together??

Maybe to tell the stupid upshift light when there aren't any more gears to shift up to?

It still comes on in 5th... At least mine did.

Only 2 of the wires are used for the back up lites.

 

Terminal A - 18 Black/yellow tracer (feed) and Terminal B 18 Brown (sw).

 

Terminal C and D are not used on the manual, and are just a 'carry' over in the harness from the gauge fuse. It's confusing because of the voltage present at the connector. You could tap into the connector for some under body glow lights :D

 

The Up-shift lite is controlled by the ECU, motoring the engines RPM's. I like when it comes on doing 70+mph and I ain't got no more gears :hmm:

that's what I wanted to know, I just re-did that on my jeep so the BU lights would work with my ax-15 and I didn't complete the loop (like on the stock harness). I just want to be sure that wouldn't cause another problem later.

Pull that stupid bulb out if you think the shift light coming on in 5th is annoying.

 

I doubt anybody listens to it anyway.
