In the instructions, it states to hook up the wire to the scavenge pump wiring. The red goes to the red and the black goes to the black. However, there are 2 black wires there. One is ground and the other goes to the wiring harness.

Which black wire do I hook the elec. check valve black wire to?

I have already hooked it up to the black wire that goes to the harness, but need to double check before I start the car up.

thanks a lot!

 

i dont think it matters, i have a G35 and i have the 2 black wires tied together going to ground.
