Coupe GT - unknown dangling wire

[laraa at sympatico.ca]

Marco, 

The shift light is triggered by load (via an intake pressure sensor) and won't come on if you are in 5th (no upshift possible!). Many people disable that circuit so the shift light won't bother them in the daily traffic.

According to the wiring diagram, track 117 is for the upshift light and the wire color is indeed br/w.

And from the drawing in ETKA, the 5th gear sensor is indeed at the back of the transmission, on top and not too far from the reverse gear switch.

Have a nice trip !

Louis-Alain

Huw, the color is brown/white and has a female spade connector at the end of the wire.

L-A, I never saw the up-shift light come on... I use the whole rev band thru all gears (not fifth of course:)) couple times a week.


Thank you all for the fast response !
I have the feeling this is nothing major but still .... :) LOL I hope the fifth gear switch is not on top of the trans if thats what it is !
