Attached is a diagram of typical GM wiring of the engine. I don't know if you have one wire or three wire hook up. This shows both.

If your speaking of the 3 or 4 wire connector to smog witch put engine back at 6°before top dead center i know about that, otherwise the computer will control.
Expert:  Roy Scarlett replied 1 year ago.
The wiring was for the alternator, does your alternator have one wire(heavy red) or three wires ( heavy red, power and 2 wires in a white connector)
Customer: replied 1 year ago.
it gas a heavy red and the 2 wires on the connector. My other issue is in the 2 wire connector, it broke in peices so i dont know which wire connects to what? They got mixed up so, i the connector it was jusg in and it was good but like i said it broke and now do not know what wire goes on what side?

Either way i tried connecting them one way ran truck for a while still no charge then switch wires the other way and nothing. So i got to figure out the correct way, then i thought of running a whole new wires from alternator to wherever thay go and im sure it will solve issue but i need the correct charging diagram.

Then after that i have to figure out why my truck will not pass smog. I was told tgat they abort dyno because it either shifts too early at around 1500 to 2000 rpms at 15 to 20mph.

It sounds like a bad alternator, if you don't have a voltmeter to hook up on the battery to check voltage output which should be 14.2 engine running. A quick test is to take the battery terminal off the battery with the engine running, if the alternator is working the engine will stay running. As far as the transmission shifting too soon it could be either a miss adjusted detent cable or governor sticking. The detent cable connects from the carburetor linkage to the gas pedal, it helps regulate transmission to acceleration. There are different transmission repair shops which will road test at no charge to diagnose a problem.

I am attaching a diagram of the alternator (generator) showing the color of the wires, Red and brown.
Expert:  Roy Scarlett replied 1 year ago.
Sorry, forgot to attach the pic. Here is the alternator and a pic of the carb and detent. Youtube has videos on how to adjust the detent cable, video is better than me trying to explain.
