And then how did Blueprint programming the ECM. What did they expect it to be doing?
And what ECM wiring harness configuration do you have?

I will get the exact specs but the relays and harness for the dual Spal fans are included with basically a on off switch at 195/175. The ECM for the engine is a GM setup with the power wire from the ECM to the fans. I would think it would work since it would send the power when the temp was reached on the engine. Thanks
