Fuel Guage Sender

Does anyone know what color the wire is on the fuel pump and which plug it is in that I need to connect my fuel guage to on a '98? The Chilton book for my truck is useless!

my pump wire is brown and the ground is black. Alldatadiy.com? Maybe Hummertech or NITROUS has a harness diagram for you.

I already fried my Auto meter fuel guage because I went by the chilton book. I went and bought an Equus guage to replace it and I don't want to fry it too. The Chilton manual says its a pink wire that goes to the guage but there is no pink wire coming from my fuel pump. :whack:

Grey wire is power to the pump. Black/white stripe is ground.

Ok, so what are all of the other wires for? Does yours show a purple/white wire?

Purple is Fuel Gauge Sensor Signal (from VCM to intsr. cluster)

Ok here is what Chilton is telling me. One schematic that reads 1988-98 c/k wiring says:fuel pump/fuel guage -pink-to fuel guage. Then another schematic reads 1988-98 c/k wiring says:To fuel guage(tank unit)-ppl-W connecter of the instr. panel connector. I don't see a pink wire on either one of the plugs on my pump and I only see a purple/white stripe wire, no solid ppl.

Thanks Nitrous. Stupid question for ya, where is the VCM?

I&#39;m at work and I can&#39;t remember if it had a white stripe or not. I&#39;m fixing to leave so I can get you all the information you need from the dealer manual as soon as I get home.

That&#39;s the old computer you took out.

FWIW, generally pink wires are switched power leads and red wires are constant 12V sources. Black and black/wt are almost always grounds. Process of elimination may help. Grey is fuel pump power so there goes that one.

I&#39;ll check back on this thread when I get home, later bro&#39;s
