Mick’s Brilliant idea 72 Dart Swinger

Great car, Mick! What's your recourse? At the risk of being a smartass....which I am a lot of times, but I'm not now, learn to do it yourself. Buy a factory service manual. It'll have the wiring diagrams in it. Learn them. Buy yourself a decent multimeter. I got an older Fluke on ebay years ago for a song. Learn how to use it. It's not difficult. I can drudge my way around most any electrical issue on cars and I'm way stupid. If I can do it, anybody can.
