I'm putting a heat AC unit back in a 71 swinger . It also has a 73 dash so some of the connectors are a little different. I spliced a couple of newer connectors on .The color code looked the same.I ran the hot to the black wire in the 3 spd switch and the green wire on the blower motor to the green wire on the 3 prong resister connector. Now all 3 motor speeds work but won't shut off when I push the off button What did I do wrong? Thanks Jim
