Hey guys, i wired my Efans to my PCM the other day..

Pin 42 on the blue conector with a PCM Pin ran to the ground of the relay..
Got the parameters right with EFI Live... and im only using one 30amp relay. the fans comes on when the A/C comes on also... very easy... i dont see any need in 3 relays..
I also ran a switch to cut them off when i want to or turn them on...

 

Your using 1 30 amp relay for 2 200 watt electric motors that both have 2 speeds??

I know very little about electricity, but that doesn't seem right

 

hahah,,, nooo.... im using one 30 amp relay to control Both motors...... only have them set to go either Off or Full Speed. sorry for not clarifying.
