My car is a 91 RS and it has a ZZ4 crate swapped into it and no computer any more how can i get my speedo and gas gauge to work now? does anyone have a wiring diagram to help me out with the routing of all the wiring in these two circuits?

i dont see anything about the speedo or gas gauge in there and also i have no ecm so i need to know how to wire it the oldschool way

 

I could be wrong, but I think the guage is wired in series with the fuel pump circuit.

 

if it is in that diagram i dont know how to read it and all that stuff runs off the ecm in the middle that is an ecm diagram

 

Nope, that is an engine electrical diagram. That's what your wires looked like before the zz4 deal. I'm gonna check my chiltons after i eat. I've seen the fuel level sender unit in there.

 

by the way thats a hot car

kinda reminds me of mine...

 

Ok, i lied. I believe it's on its own circuit. Looking at the diagram, 2 wires lead to the tank for the fuel gage. One being pink, the other black. Both go through a connector named C313. From there, the black goes through ground distribution spot G304. The pink leads to the fuel gage in the instrument cluster. Coming out of the fuel gage, is a pink/black wire (C1 on instrument connector) which leads to the fuse block (10A fuse).

Hope this helps.

yes it does thank you now i noticed that my speedo works when the headlights are off but not when they are on and the dash lights on the speedo and gas gauge dont work when the headlights are on but light up dim when they are off but the rest of the gauge lights work normal

does this seem like a ground issue?
