1) Ground terminal No. 8(black/white wire) of Data Link Connector (DLC) Located under lower left side of dash. Reciever will respond by locking and unlocking doors within 2 seconds. Press any button of first transmitter to be programmed. Control module will respond by locking/unlocking all doors and activationg liftgate release

2) Press any button of second transmitter to be programmed. Control module will again respond by locking/unlocking all doors and activating hatch release. Remove ground from DLC terminal 8. Transmitter operation can then be verified. Attempt all functions with remote.

Thanks Onblsht!!!
