Yep Oddmar you would think that is how they would have been built. This is my first toy so its learning something new for me. I thought it was going to be easy when I discovered there was already a plug for the fact rear defogger and then discovered they didn't run a wire up through the cab to the rear glass but I have already taken care of that, and installed the fact rear defrost glass. I almost have completed removing and labeling the wires from the donor truck for the power windows and have started retaping them to make a loom. I probably could have used the whole harness from the 86 in the 88 truck but looking in the Mitchel manual I see a few differences.
