The EASIEST way to wire one is with a Painless Harness. If you insist on doing it yourself. 1. Do your start ignition first 2. your one wire alternator 3. all your relay circuits (rad fan, fog lights, horn ,wiper) 4. your two speed wiper 5. your lights with turn and hazards 6. accessories (DVD, speakers etc) it can seem mind boggling at first, but it is really simple
