flashpro harness adapter

The instructions say to plug the flashpro harness into the green connector located in the top left area of the glovebox but the connector is in a really tight location and hard to get to. My question is, can I solder the harness to the CAN high/low wires found behind the gauge cluster instead?

No, because that would create a branch of the CAN bus with an incorrect termination resistance.

So the harness must be connected to the green junction connector? Not even spliced into the can wires right at the ecu connector E plug?

Thanks. Got the harness installed and flashpro seems to recognize the used 07 ECU correctly. At this point, the dealer shouldn't have any problems pairing it to my immobilizer right?

As long as it is wired correctly it should work.

Went ahead to the dealer and they were successful in pairing the ecu and immobilizer. Also was able to upload calibrations to the ecu no problems.

One minor issue was I had to reprogram my remote starter immobilizer bypass module (PKH3) afterwards. Remote starting the car only resulted in a crank but no start situation. Green security key light didn't come on either while the car was cranking which was weird.
