ok, that helped a lot, it makes sence if the fuel pump wire goes to ground. and ill use the fule pump wire as "ground" for the asd and fuel pump realys that way the ms is controling them. as for the tach , i have 2 gpo's i beilve so ill investage what it will take to get that working as a fan control and Tach signal.

this is more like what you are showing/saying?


15amp should go inline with fuel pump, i placed it wrong **
