Need Help Asap Please!

I went to the JY and looked at a 75 Duster they still have. The plug was right next to the left side of the glove box. All 3 wires were hooked to a red plug that was attached to a relay. Those wires are part of the main wiring harness. If you reach up under the dash to the right of the ashtray, there should be several wires taped together. Some run to the horn relay and some run to the door switch. It should be easy to pull the harness from under the dash and look for where the wires are cut. If you can use the harness out of the Duster let me know.
