Should be easy to add it.My 06 LS does not have it, but the 02 Silverado I got the HD hood off of did. Damn if I didn't grab it then though....grrr..
Get the new part (It is $20 prime, for new GM part on amazon right now), go to the salvage yard and get the wires off a truck there, attach to power and ground, and you are set.
