Bryan,

Just to be clear on the relay's. You still need a large wire on the main power into the relay and out to the pump. I use 10 or 12 ga. depending on length of run, on the cars I wire. You can then use 14 16 ga on the switch wires. I use relays on the fuel pump, water pump, and electric fan. I also put fuses on everything. Some like circuit breakers, I like simple with fuses.

Also, as several have said, make sure you ground everything. I probably over kill this, but I use ground straps on the heads to block on alum head combo's, block to frame/cage. I chased a grounding issue on a car years ago, and swore to never miss that step again!

Good luck.

Ken
