to be honest, its not the concepts that has me confused all the time, its the relays, and wiring mazes, even colored ones, I have trouble getting. Basically, what I set out to do, was to bypass all the unneeded functions in this harness and just have the bare minimiums to run the car and charge the battery. But I'm thinking I'll just order that entire new harness for 700 bucks, I'd be months ahead at this point lol
