Sunday, (yesterday) I used a SPDT power relay to install an aux. circuit for the I/C pump and done as I stated in the 6th post on this thread. The nice thing about the way it is set up is that I can shut down the engine, leave the key off and turn on the fans and pump from a small key fob. The fans were already connected to a fused constant 12 volt source so I hooked up a fused constant 12 volt source for the aux. pump circuit. The pump aux. circuit relay is turn on by the remote control fan relay with a little green LED mounted on my HE temp gauge to let me know the pump is running. So this sould help cool down the I/C coolant while circulating it with the fans sucking 660 cfm of air through the HE between runs at a track by shutting the car down and clicking the little key fob. That is if I ever make it to a track.
