Basically I want to use the stripped down 90 dash harness, eliminate all non used electronics so it basically powers everything and allows for the 82 harness for power window and mirror controls to remain in stock location. But my main reason for making them work together is to relocate the fuse box and make easier to power the 90 tpi harness.
I'de also like to fill in the dash holes for wiper controls and utilize the 90 steering column with wiper controls on it.
