For those of you who put in manual switches, did you splice the wire right after the relay and run a wire through the firewall for the switch, or did you splice it right before the ECM. The reason i'm asking is there are three green and white wires running into the ECM and i have no idea which one is for the fan, and what the other two are for. Thanks

splice after the relay from the engine bay and then went into the car through the fender well / between the door. also run the ground wire from the engine bay into the car from the fenderwell.

 

Thanks, I appreciate all the help.
