I just bought a power window conversion off a g2ic’er and i was wondering if there are harnesses from the fuse box to the door? or would i have to buy that, because he did not include that
No power harnesses in the door unless perhaps your car has factory power locks but no power windows.
You can buy these harnesses for about $40 a side as I recall. You should be able to make your own harness with molex connectors, hard wire it, or rip one off a wreck. A friend of mine removed one before and said it was some serious trouble to yank it out.
