Had a question about this. The gause I have has a sending unit attached to the wires. My question is that if I use the sending unit attached will that mess with the pcm?
If your gauge, wires and sending unit are a package unto itself, it won't bother the stock stuff. The stock gauge does not interface with the PCM, anyway.
OK. There is a place in the firewall on the pass side but I don't think the wire is long enough to reach. Is there a better place to route this from the drivers side?
