A buddy of mine has this truck and wants to put keyless entry in it. It already has power door locks.I was looking at the wiring diagrams and it seems like a pretty simple install. I was told that I would just need to piggyback the lock/unlock wires at the BCM. What does piggyback mean?? Is it the same as splice?? Thanks

never heard the term piggyback. But yea, splice into the wire (or if its hard to reach use T-taps)

please dont ever use T taps .solder and tape at the least. ive been installing a long time and have never had to use a T tap and i cringe when i see them. thay are are by far not a solid connection

bring back the rotary phone so i dont have to press 1 to proceed in english

i dont use them often, only when i am forced to. There are some cars where they place the lock/unlock wire up and behind the fusebox and there is no way my hands can reach up there.
But i do hate installers who overcharge and use T Taps

I wasn't aware that this could be done by using a harness. Care to elaborate. Thanks

Red97LT1,
First, I don't think I've seen a GM full-size SUV that did not have keyless entry as standard equipment........probably, the thing already has keyless; just buy some remotes and figure out how to program them. (It's possible you'll have to pay the dealer for programming.)
Otherwise, it's an easy car anyway.
The lower driver's dash panel comes off with two 7mm screws......behind that, there's a heavy metal bolster you'll want to remove; four 10mm nuts.
After that, the wires are pretty much staring at you......constant and switched power are in the harness going to the steering column........lock, unlock, and parking lights are at the BCM immediately below that.....and there is plenty of bare metal around there to use for a ground.
If you were really in a rush, you could also find lock, unlock and constant in the driver's fusebox, with no disassembly required......although I don't think you can get switched power, or parking lights there.
