Wiring Instructions for Aux Gauges into an 88 4 Cylinder

[GTRS Fiero]

The hardest part is getting the 2 plugs out of the back.

Mine takes longer to assemble, because I have more pieces to line up.  I just removed mine, last night.

All done and all correct!  Even with my condition / tremors I got all the needles in the correct position.I just connected the scanner, started the engine and went according to the readings. In diagnostic mode, the auto Duke is supposed to run about 1KRPMs, so that is where I placed the needle while running.What I wouldn't give for a steady hand......took about 6 tries. Same with fuel gauge (filled her up first), the placed the needle (while ignition on) in the full position.I would not recommend doing this without a scanner........and a steady hand of course.

Glad to read this.

Hey, Don, did you forget about this method?

I think I would have placed the needle at the E(mpty) mark with the ignition turned off.  For the reason that I'm more concerned about when the tank is reaching Empty than when it's Full.

I agree in theory, but it seems that off is not empty.

Charlie.......apples & oranges. My post from way back when was actually to clean the sending unit inside the tank without actually having to drop the tank. What I was dealing with here in the last few days was the incorrect position of the needle on the gauge, not incorrect values from the sending unit.

Mike is right. In the "ignition off" position, the needle moves to a position that seldomly corresponds with the "empty" state of the tank or sending unit, it is just a position the needle goes to (magnetic charge) on the gauge. Almost never correct.

I'm going to have to remember that word, "seldomly".
