Rhodes Posted June 1, 2021 Report Share Posted June 1, 2021 I need the wiring diagram and am having a heck of a time finding one of that year. I can find mid-late 80's trucks but not as early as '82. Any help would be appreciated. You may think I'm nuts but I'm actually fitting the underdash unit into a project vehicle and would like everything to be correct. 1 Quote Link to comment

Charlie69 Posted June 1, 2021 Report Share Posted June 1, 2021 (edited) Are you using the heater & AC? Edited June 1, 2021 by Charlie69 Quote Link to comment

Rhodes Posted June 2, 2021 Author Report Share Posted June 2, 2021 The AC relay appears to be fixed to the top of the AC box, but do you know where'd the heater relay would generally be found? EDIT: The heater relay is a blue relay plugged into a blue plug; this plug is actually clipped into the fuse panel on the interior, drivers side near the hood latch. 1 Quote Link to comment
