I have the NOS 15974 mini controller. The controller has two heavy gauge wires to use for both stages to the solenoids. The diagram shows to wire them straight to the solenoids without any relays between the controller and the noids. The only power source to the controller is a small gauge white wire for the coming from the main switch.
Can I put relays between the controller and the solenoids? I don't see How that one small wire can support the current for the solenoids. This is the wiring diagram.

If im not mistaken, the relay's are built in the box the wires itself are coming off of.

The blue and red send the ground signal.

Thanks, I was looking at the diagram wrong. I thought that it should be like rpm switches that hook up to the ground side. I can just hook up the 12V side with relays, Correct?

Yes the solenoids can be powered through relays. See attached schematic.

Thanks, that will work I like that diagram better.

I am trying to hookup a 15974 NOS progressive controller to an MSD 8625 Timing Twister for my stage 1 retard. Love the diagram in the post above

It is my understanding the yellow ch1 output control wire outputs a ground signal. Would this be the trigger I would use for the MSD retard? Since it is a ground output I assume I would use a relay to "convert" to a +12V signal?

Thanks

I have the same question. Sorry this is an old post guys.

Yes a relay would be how to convert from a ground to a +12V signal.

Thank you. Does anyone know if there is a diagram for this set up floating out there on the net.
