I have a bunch of wires from the unused wires from the original 305 engine the previous owner installed. The temp sensor on the engine has no wire going to it and my temp gauge does not work due to this. Anyone know what color wire goes to the temp sensor? Thanks so much in advance. Nel

 

Im guessing its either black (standard) or could even be possibly a dark blue with a white tracer......

Memorys not what it use to be...lol im old...But im pretty sure!

 

I will be by the car next week and will search for these 2 color wires and see if I can perform a miracle and make the gauge work. Thanks again so much for the reply and I will post back to let you know how well your memory still is

 

Another option would be to use an after market temp gauge! That you could mount under dash..The only power you will need is for the light..

It comes with its own power lead...That you can plug into the fuse box..
with the fuse for the headlights!... That way it lights up when you turn on the headlights!

 

Do you have access to a library, either brick-n-mortar or online? A repair manual? Your best bet (imo) would be to locate a wiring diagram for the vehicle. Then you'll know for sure what wire is supposed to go where.
