Anyone use a MSD Solid State relay for relay block? I would have it setup to use:
MAIN power -- ignition trigger
Fuel Pump power -- ECU positive trigger (green wire)
FAN Low -- ECU negative trigger
FAN High -- ECU negative trigger
The downside with the MSD SSR is that you can not setup the relay coils to be ignition+ and a ECU ground as trigger (either positive or negative triggered - not both) so my concern is if the ECU pulls the fan relay signals to ground when off; or keeps them high/float.
It would really cleanup the wiring in my swap
