you don't, it either works or does'nt, check all grounds, put power to it (12) volts, sending units are very delicate, care must be taken when replacing, in tank, . a wire diagram would show you the power wire, the ground wire, etc., maybe you can check it ?

Usually the blue wire from the stereo is for the remote amp and/or power antenna. If you haven't cut off the stock radio plug, I would check into getting a stereo harness adapter for the stereo. Most auto stereo shops can get them.

If not under your hood then i would suggest getting a GM. repair manual.

The fuse block on all models is located under the left hand side of the instrument panel. All flashers are mounted on the fuse block. Each fuse is marked on the fuse block as to which circuit it is protecting. Some early models also use an in-line 30 amp, fuse for the air conditioning hi-blower, located at the cowl relay and an in-line 10 amp, fuse for power antennas.

Hope this help.

gray green and black wires? or red blue and black wires?

hmm..there might be a fuse box under the hood or most likely in the dash or under the passenger or the drivers dash..hope i solved your problem :)

See if you get power from the gray wire. Use a 12 volt bulb, or a multimeter.
