I am wanting to trigger the fans from signal wire that activates the oem AC compressor,,, can I run this in line with the trigger on supplied in your harness? Your harness made my swap easy!
the simplest way would be to use a vintage air trinary switch. our fan relays are ground triggered, but the switch is the best way. Also we are thrilled to hear the harness helped to make your swap easy!! we Love to hear it!
In your video you have two fan connectors coming off the cooling fans. Can both fan’s wiring be routed through a single connector and use a single relay wiring kit or should two separate kits be purchased, one for each fan?
These relay setups are generally for single speed fans to turn on and off. If you like sent us an email with your fan model and we will look into it and see if we can help your setup get up and running.

Hey psi love your product At what temps do the fans turn on???
Hey Thanks! we program our computers (depending on the computers of course) to turn on around 190-205.

We recommend that you use one relay kit per fan for your swap. I hope this helped you out with your swap.
Thank you for your response
I have a PSI harness. For dual fans, do I need 2 relays?
We recommended that you use one kit per fan on your swap.
So if im using the relay kit and i dont have a psi harness (still have a sbc) is the blue wire a ground trigger?
yes it is!
What if you don't use the blue or green wires
How can i make this work with a dual speed fan?
