Just to clarify, if you are putting full power doors on your 77 that is not equipped with power accessories, you'll need a complete center harness at least and at most both door harnesses unless you managed to retain both LH and RH door harnesses. But, if you want to convert to relay power or add the auto-down option for either side, you'd be better off with a complete harness to keep everything simple. The relay splice kit is designed for trucks already equipped with factory power windows.
