Exclamation Help with exhaust cutout switch

Hi everyone,

Have an issue with my exhaust cutout.
I will try and explain my crude paint wiring diagram as best I can.
Left: How my exhaust cutout was wired. Could open or close with a remote. Something in the control box malfunctioned, and it started melting (worked for almost a year)
Middle: (Control box gone) wires straight, will open the cut out
Right: (Control box gone) wires crossed, will close the cutout
Any one know how to wire this up to work again, maybe with a relay and a 3way switch? I obviously don't want to swap the wires every time I want to open and close.
I'm have a basic understanding of electricity, but I just can't seem to find the simple info on things like DPDT 3 way switches to wire it correctly. Thanks for any help everyone!

What you need is a DPDT toggle switch. This is a double pole, double throw switch. It allows for 2 different inputs and one output (the DP side) for each of two switches (thats the DT) - even though it looks like and toggles like a single switch. This means each side has two inputs and one output. You would cross wire it so the inputs are reversed when you toggle it.

Try doing a web search for "Wire a DPDT switch for reverse polarity" to see how it is wired. very straightforward.

You need to determine if the cutout requires constant power to stay open and constant power to stay closed.

You will need a DPDT center off switch if the cutout doesn't require continuous power.
OR
You will need a DPDT switch if cutout requires continuous power.

Either way.... you probably will need to use an ignition source for your power so it goes off with the key.

The cut out does not require constant power. Only about 1 second, and it opens, or closes.
I will look into what you all have posted here. I appreciate the help, think i need one with DPDT with center off switch

You can also get a DPDT center off momentary contact. That means the switch stays in the middle and you tap it up or down.

Amazon has a few choices. The one for $4 with the red on on plate would work fine. There are also rockers there you could use. The on/on plate doesn't have to be used.

Amazon DPDT switches

Detailed switch from Amazon

This is just one source. There are many.

Most large electronic parts stores if you have one local. If not Newark Electronics, Allied Electronics, or DigiKey comes to mind. They all have searchable web sites.

Thanks PJMax, I never thought about Amazon for electronic parts. Good call. That will help me too.

It has numbers going counter-clockwise 1-6.

Can you draw me up another diagram?
I would like to use a 12V+ ignition power source, and a new ground.
As I mentioned before I need the up position to open the cutout, and the down position to close it. Thanks for any help everyone! I appreciate it.
