DIYPNP - Can't get WLED output to turn on radiator fan
So I wanted to use electronic boost control and realized that the only output I had available to do that was PA0 which I had been using to turn on my radiator fan. So I switched the PA0 output to the IN point for boost control and it works great. I didn't get to play with it long, though, because I noticed my CLTs were well past the allowed 207 when I pulled over to play with settings. Sure enough, no radiator fan.
I have the WLED output at the top of the board (near the DB9) connected to the IN on RELAY 1. I copied settings over from PA0 to WLED (1 and 1, coolant > 207, hysteresis 10, no additional conditions) but the fan just isn't turning on.
I made sure the connection for WLED was good from the Microsquirt to the IN port on the relay. 0 ohms. All I did was move the wire. Any suggestions?

I'm running sequential so I can't do this.
WLED can drive a relay directly; you don't need to run it through a relay circuit on the main board.
^^Will try this before work and post results. I didn't realize WLED could do that. Haha, if I knew how to read, the DIYPNP Outputs page even says that!
