1986 trans am

my car was originally equipped with the digital dash cluster. the wires are all still there, and i was wondering which wire can i use to install a aftermarket fuel gauge. im looking for the wire that goes to the sender. also is it possible to use the old sender or will i have to replace it. thanks

 

It is the pink wire going to pin "5" of connector C2 (34 pin connector). If you need a pin-out of the digital cluster connectors let me know and I will post it later. BTW, you can use the same sending unit.

 

there are three wires neer the hump in the backseat that will give you the idea of what the wires look like

 

the connector was cut, i think i found the pink wire tho. do you have a diagram of the wire colors and what each of them does?

 

Try this, it might help http://www.hioutput.com/tech/speedo.html go to the wireing printout link and it will list all the dash connecters and the color wires
