Do you have a plan for the H bridge relay that you need to make that switch work? I looked into that for mine and it's pretty much a complicated bummer.
No I don’t, this is the first I’ve heard of this. What’s the big deal? The motors aren’t high amp draw, I don’t see the need to run them through a relay unless there’s something I’m missing?

Not familiar with cut out wiring but it's possible it needs power to open and close. I would think that you need a 3 position momentary toggle at least

Bi-directional DC motor needs some sort of H bridge, not relay (my bad). I was gonna get Holley to run mine from the ECU but ran into this and got frustrated. I was hoping you had some kind of secret solution I could use.

Thanks for the heads up on this. A quick interwebz search turned up a site where somebody had posted a link to this:


Looks like I’m not the only one who has considered wiring cutouts this way, there’s a switching polarity controller box available for just this purpose.

Not sure how or if you could incorporate this into your build, but this would certainly work for me. The video is somewhat informative as well, multiple ways to wire the switch(es) and the opening and closing times are programmable.

Many door lock or window switches will work that way too, so you could just find the ones you like, OEM or aftermarket and wire them up like a window motor.

Got a pic?
Many online. Used to work on DC motors for bridges when I was in Chicago. I'm talking about 600vdc and massive 150hp motors and gearing some of which was made in the 1800's. Relays and motor starters/contactors all worked similarly. However the link D provided has stuff that would more suit what he needs at a higher cost.
Also what random farmhick stated would possibly work as well. Do these cut out motors have end of line switching???

Way more complicated than it needs to be.

You simply need two single pole relays, and a couple of diodes.
Hell for that matter, you could probably just use a power window switch. They operate the same exact way....
