CSR EWP wiring???
I would link you to it but its down right now as I can't seem to log into that section at the moment. Maybe it will be back up later.
Battery (constant)power comes from the positive junction block behind the battery. Or you could just come right off the battery positive terminal.
Signal (switch on) power comes from the pink (w/white stripe) wire in the fan relay.
Ground goes to the ground strap up under the fan relay. Or you could just go right to the battery negative terminal.
I mounted the electric water pump relay right to the bottom of the ECM bracket and tapped into the pink (w/white stripe) wire in the main harness which runs just under there on the fender well.
For the 2 waterpump wires. I used an old MSD dizzy 2 wire harness with weatherpack connector. I ran the 2 wires out of the waterpump relay under the ECM bracket, down along the firewall and into the injector/optispark harness, then over to the waterpump.
It looks like GM grew it there.
