So I'm going to be rebuilding either my tail gate or a new one for my 75 k5. I'm wanting to do power window. I'm wanting to make sure the wiring is going to be good enough to power the window up and down fast. I've seen the post for using relays for power windows. Is there any way to convert this over to the tailgate? Also where is a good place to get all the parts I will be needing. LMC doesn't have much for the k5s.
