I don't have the FSM handy at the moment, so I don't know what that ECU pin 1O is supposed to be doing.

I worked out the fan issue. It was too small of a fuse I put in there. I had a 30 amp fuse. I put in a 40 amp fuse and haven't had any issues.

Good deal, I assumed you had a 40A fuse in there. 30A sounds about right for a fan circuit. Normally you'll want your fuse rated about 10~15% higher than the worst-case current draw your circuit will see in normal operations.

I thought I had put a 40 amp in, guess I grabbed the wrong one and hadn't noticed.
