Freds 73 Scamp restore on a budget

20191227_162501.jpg OK need to start looking into wiring next the thing I suck at the most. So I need to ether replace it all or fix what I have.
American autowire has a nice complete harness for 1000 bucks that is better than painless wiring at around 700. My wiring is in good shape but the normal bulk head plug in sucked so is now deleted.
