IA 1973-80 power window/lock harnesses available!

[gmachinz]

Ok...I've got these available now and with upgrades over OEM design. While I can supply a 100% restoration quality harness, there are several aspects to the GM production harness that left a lot to be desired. For use with factory equipped trucks with OEM style stainless switches, I have integrated the following upgrades for a standard cab truck:

J1128 automotive grade wiring with soldered terminals

40A Bosch style IGN switched main control relay for windows

(2) 2-gang relay blocks for providing relay power to each motor

10ga window motor supply leads!

These older harnesses are different from the 1981-up harnesses I offer because of the type of self grounding OEM window motors-this, being an older design some connectors and components make this a more expensive harness kit to reproduce and I integrate relay power along with oversized supply leads to make this a much more stout harness than originally equipped. Price for a complete 3 section harness for OEM equipped 73-80 trucks is $399.

You will need to retain and re-use your existing door jamb grommets and window motor connectors-I provide the remainder of the harness. Nobody else offers a more complete and robust harness for the 73-80 trucks regarding the power windows and locks!
If there are any questions, ask away!
