bought an 89 gtu with homemade sending unit and new fuel pump and spliced wiring. So I bought all factory setup and did not get the harness to the pump cant find a wiring chart to keep stock so trying to figure it out my self if any one can tell me what wires go where that would help alot. And when I used my volt meter to check wires, with the key in the run position after like 15 sec the buzzer starts buzzing is that normal.

the buzzer is from either low oil or coolant level. The coolant level sensor is a single wire on top of the radiator. The oil level is on the pan.

I just did my fuel pump, I don't remember the color wire for the power to the pump, but maybe you can do some investigating and pop off the screws for the cover

Thanks no coolant nephew said he took the radiator out and had it fixed and did not put coolant back in it. Hopefully ill be able to mess with it this weekend to try to get it running

No he cut the plug off and tossed it. Just bought a Hayes manual for the wiring going to look over it this week.
