Wiring isn't so bad. Just give yourself a whole day to do it if you want it to look clean. Use shrinkwrap. Different color wires. Make yourself a chart on paper of what colors go where. Use electrical tape to bundle the wires and use conduit to make it look stock. Or you can run it into the stock harness which is more work but looks even better. Last but not least check, double check and check a third time when wiring so it saves you a headache later.
