Re: Where to terminate ls harness to existing harness.

Without knowing what year harness you have, it's hard to know what we're dealing with. What does C1-B11 feed? I would try to use a similar wire from your truck to what the circuit is intended for. Not sure on the other circuits either, but grey sounds correct to the pump- just make sure it is the post relay feed- the switched line from the PCM will not have enough volts/amps to run the pump.
