Do you know what changed from 75 to 76, mine is 74 duster, had bad interlocking seatbelt module, they want $150 and up on eBay for that module, I have found 2 1974 with bad modules as well as the one in my car now. You lose dash lights, cigarette lighter, turn signals, emergency flashers ,horn dome light and a few other items if you try wiring around module.
