Boost control solenoid: Optional as you can use the stock one, but I don't know the specs on the stock one.

i used a GM soenoid, and when looking at the solenoid it has a plus sign on the plug housing which designates which wire is power and which is the signal. The plug harness I got with the unit had two white wires so I had to look at the solenoid to figure it out. I used the plug in the engine bay that was used for the stock boost control solenoid re/yellow is the 12v positive wire and the light green wire is the pulsed signal ground wire.
