Agree - the light bar I got came with the relay and a 30 amp fuse, so I figure I should use it! For the other accessories, I just checked on the watt rating and divided by 12v to get the amperage. Anything over 15 amps I figure should have a relay, and anything 10-15 amps is a candidate for a relay and should have 12AWG wire if not using a relay. Anything less than 5 amps I didn't worry about and used 16AWG right to the switch panel.Interesting! I may have done just that if I had really thought about it. I have a tribe of grandkids, so the key-on power may save a few headaches. If the diode solves the problem, I'll be set. You are certainly right about space being a premium. I had already decided to forego the relays I was planning on. Will probably still use one for the 52" light bar, but the smaller lights will run off the switch. The light bar says 300 watts, so should have a relay.
