Electrical help needed!

Year one harness only provides the fused hot wire which is a single female spade as your power wire.
The sub harness that runs your heater switch and blower etc, you have to unpin from the original harness and repin to the power wire t hff at comes with the new harness.

The dash harnesses are not labelled A/C or NON A/C for a reason. The dash harnesses use the same feed wire for both. Your climate control sub harness is what makes it A/C or heat/defrost.
