Re: Dual Electric Fan Wiring Kit

Wire each fan with seperate relays. The only common connections shoud be two. One IGN source to each relay. Tie the relay inputs (on) together down to the head probe. Use a fuse between the battery and the relay. I use the 30 amps fuses. The fuses have two little nuts on them.
The head probe replaces the adjustable theremostat. The high and low side to each fan. Tie the 85 connections together. You can ground them any way you like.
