Need your guys opinion. So I started removing the in dash wiring harnesss to look deeper for broken wires. I have found a lot of wiring that looks just too bad for being 51 years old I have two options I need to ask yall. First I eventually want to build the engine up more and add a new alternator. Keeping that in mind. I see classic industries sells a new in dash same wire coloring harness for 800.00. Or there’s American Autowire that has the full car wiring for 1400 but looks a little more complicated. I am a disabled veteran I don’t have much money and my body isn’t the greatest to be doing too much work. I bought the car to enjoy and keep my mind clear. But seems that I didn’t know how bad the wiring was until I dug behind the dash. So if I go with the classic industries stock in dash new harness I also have a new engine harness that came with the car. If I do the American auto wire the full car will be re-wired kinda stuck has anyone replaced the in dash harness with the one I’m talking about ?
