Ok I have the Motiv reflex controller and a TMS wiring harness for my PI. I can’t get the Mac valve to make boost. The plumbing is right but what’s strange is when the key is on I have 12 volts coming out of both the white (ground) and red (power) wire when I test them. That’s 12 volts when I ground my probe to the frame of the car and test each wire. When I test for 12 volts using the white and red wire I had nothing.

I removed the kick panel and checked all the wires and pins. Everything is looking good but I heard the TMS wiring kit was not a very good kit. I have no knowledge of this.
Any and all suggestions welcomed.
I’m going to call Motiv tomorrow and see what they say. Could the reflex be bad? I honestly don’t know at this point.
