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
The two grounds are technically chassis ground and sensor ground, if they followed the spec.
Two wire networks are always one over the other.
I know there is some funkiness with having to use this ECM and that BCM to talk to the rest of the Solstice.
