I have the RF harness and the complete Sniper 2 system with the distribution panel and hyper spark.
Looking for input on whether to use the wiring in the RF or to control through the Sniper 2. Thanks for the help!

Do you wire directly to the sniper box or did you add a relay? Or route the signal through the RF relay?

I have an MSD Atomic 2 and have it controlling the fan. Mine requires a relay with a ground trigger.

I opted for the Holley Power Distribution Module "PDM" works with the Sniper 2 and has built in digital relays. Sniper lets you set the temp for fan or/fan off, also has a additional relays for other accessories and will run your fuel pump.

I have a Sniper and it controls the fan through a relay. The Sniper provides a ground to trigger the relay. Designed for low amps only!
I paralleled a dash switch control using the same ground trigger.

Thanks guys, I found the issue. I had to connect the black and yellow from the Sniper I/O harness AND the green Fan Thermo Switch wire from the RF to pin 7 of the PDM. Now I can control the fan from the sniper but utilize the RF relay and wiring.
