Topic: 1979 Trans Am Engine wiring

[Airforrest]

Guys,  I have this 79' that had no engine in it when i got it. Just installed a rebuilt 403, and have some wiring questions if anyone can help? Off the Alternator Harness...does the Blue wire go to the Oil Sender? and the Green go to the Temp Sensor? Then I have an extra heavier gauge wire that is short...where does this one go? Does it connect to the Idle switch on the Carb?
 Also, I have 2 wires off the A/C Harness, a heavy one Red or Pink, and a thin Green with a Black stripe? Thanks for any help !

Yes, blue is oil and green it temperature and I believe you are correct about the a/c idle on the carb -- although it should be any heavier than the oil or temp. For the rest here is a crude diagram I worked up for another post a while back. Hope this helps

Thanks ! Got them connected, but no movement on the Gauges. Tried to ground them to the Block....still no movement :-(

Do you have the U shaped bracket under the steering wheel installed? The ground for the instrument panel also runs through that bracket.  If it is not installed you may notice weird things happening.

It is.....But, I will sure check around it for loose wires !
