cool little unit! you can output your ground ECM signal to the ground wire and provide fused +12v to the inputs to make it function without a relay for either single or dual fan/pump.. but a single relay is the better option.

A relay to run a relay? I think you need to show why people would what it as is a + trigger 80 AMP relay, I for one would benefit from that, HAA HA

by using a normally closed small amperage relay, you can run single fan/pump mode and then when relay is open trigger high for fan/or second pump. or you run it without a second relay as i described above.

Holley only have swt to grd outs. So just run that to a ground side of relay and run the hot out to the swt relay. My air conditioner kick off is wired like this as the vintage air need a swt 12 not a grd. Hope that makes sense. We will have a wiring class soon for those that want to attend.

@@MonkeyFabGarage yes !!! wiring class, I just found out yesterday what I needed need using , say the MSD solid state relay, with the screw that squishes the wire at each terminal , I need to use a bootlace ferrule , HAA HA Still don't understand why this relay is all that, and some how I know I could use a dual output high amperage relay, and I believe with my Holley Dominator system, I can make the trigger - or + , sign me up for the class too!!!

@@MonkeyFabGarage i do alot with stock ECMs which are all (pretty much) switched ground. so that's why i guess i mentioned it. keep up the good work!
