02 Sierra . Bcm blues
They have power, no ground. Ordered a used bcm off eBay out of a 01 Tahoe . Do I need to go to dealer to have programmed? Any help appreciated, thanks
If the BCM comes from a vehicle with the exact same options as yours, there is really no need to reprogram it.
If you want to avoid the dealer cost, install it, do the 30 min relearn and test it. If it works leave it be.
