Fuel gauge wiring question
On my 74, the wiring harness going to my stock fuel gauge has a pink and a brown wire. Which is from the sender and which is ground? I am hooking up my Nordskog gauge panel and the directions say to attach the wire from the "factory fuel level sender". :confused:

Its hard to follow all those thin lines but try a magnifier and maybe a highlighter to trace out electrical path. :lol:

I saw that brown wire on the tank but it looks to be a 18 gauge while the brown wire at the gauge is a lot thicker, maybe a 14. I'll call Nordskog today and see what they say.

Re: Fuel gauge wiring question (Brettmc)
In GM wiring the pink is always ignition switched, pre-fuel injection tan is the wire to the sending unit (tan is also used for the brake warning light wires). Just FYI, later FI cars the wire to the sending unit is purple and the wire to the fuel pump is gray. I burned up a sending unit when I put TPI in my truck. GM now gets about $250 for an 87 truck sending unit-oouch! I put 12v through the sending unit and it never worked quite right after that.

Re: Fuel gauge wiring question (markdtn)
I knew someone here would know this obscure piece of info!! I did notice last nite that the e-brake connector had the same colors and assumed that it would be the same type setup as the fuel connector. Thanks dude!!
