Going to make an attempt at a thread showing how I made an adapter to control my NPP exhaust using the fuse under the dash. Not experienced at posting this kind of stuff so please bare with me.
I started off using a basic fuse tap available just about everywhere for a few bucks.
Top fuse is for the new circuit, bottom for the existing circuit. The far tang provides the power for the new circuit.
The two ports on the left are connected, the two on the right are not. This allows for 2 fuses to control 2 circuits.
Split it open to reveal the basic innards. The red wire is connected to the far tang through a fuse. That's where it will stay.
Remove the small tang.
Solder a new wire onto the small tang removed from the tap.
The tang can now be reinserted back into the tap. I had to notch the plastic to allow the new wire to fit into the bottom of the tap. You can see the new direction of current flow.
Liberal application of epoxy just to hold things together. I clamped the two halves of the case together until the epoxy was set.
Two halves epoxied together and a little shrink wrap for support.
Only the top is to be used with a fuse. The bottom openings are epoxied closed as this side is not used anymore.
Finished product. If done correctly, current will flow in one tang, through the fuse, out one wire to a switch in your location of choice, and back through the other wire straight to the other tang. Simple two wire NPP control.
That’s nice, but you can by the wireless remote which I hooked up in mine and friends which is exactly like the ones with the mild 2 wild labeled they sell for 80 bucks for under 20 bucks.
Very true. I had a M2W on the car when I purchased it. I just found another fob to deal with a pain. A simple out of sight switch was more to my liking.
Cheers.

This looks like Amazon? If not, who is the seller? And how did you determine which to purchase? Thanks!
Same as the OP, I bought an NPP car with M2W and wasn’t a fan the remote so used that hardware and a foot switch on the dead pedal. Later on, found this at RPI Designs. M2W Exhaust Controller - Old School
Would have just bought it.
Forgot to mention: Thanks OP (Chippawa) for taking the time to share some good work.

I ordered the dead pedal switch because I really didn’t want more things to carry and damned if they didn’t get it wrong and send the one with two fobs. Probably be the last time I order from them.
