HELP!!!! Ok here's the deal, I swaped my engine out from a 6 to an 8, I got the harness from a manual and mine is automatic (not that it matters, but just in case) The heater and wipers went through the main harness in the car as a 6 and I do believe those two things went through the secondary harness from the drivers side on the V8. Well I am at the point were I sort of need both, ie. windows have dew in the morning, and heat would be nice. So I guess I need some wireing diagrams from both cars or something, my manual got eaten by the swap monster, accually most things disapeared too, anything would be helpfull.

 

Here are some '85 diagrams on line. The HVAC & wiper circuits should be similar.

If you get desperate, manually move the doors inside the heaterbox to the defrost position and run a wire directly from the battery to the blower motor and another wire to ground. Will give you heat at all times with the blower motor always running on high (even after you remove your keys from the ignition).
