I am trying to wire up my obd2 port, so I can use hp tuners, on my challenge swap I think it is a 2008 solstice engine.
My obd2 port looks like this:
I have green, then black, then black with white stripe, then tan, tan with black and red with white.
I think both black wires go to ground
Red with wire is 12v
green I have hooked up to the body control module connector 2 wire number 11.
where do the tan and tan with black go? To the ecu tan and tan with black?
here is my current link between bcm and ecu
