Custom Accessory Switch?

Post by Christopher72 » Fri Aug 11, 2023 3:15 pm

Has anyone added a custom accessory on/off switch to their zed to control custom-installed accessories like radar/camera/lighting?

If so, where did you place the switch, and did you install something that fit the look and feel of the interior?

I installed a bass control knob for my sound system in the little cubby box on the drivers side as you can see in the photo below. Makes for a discreet hidden installation.

That’s neat…
We choose to go to on with this endeavour at this time and do the other things, not because they are easy, but because they are hard…

That's a good idea! :bow:

I dont have the skills for this but could one of the spare buttons next to the heated seats/roof buttons be used?

That's possible but I think it would be difficult as those buttons are all part of one control panel. You can see the photo of the rear of this panel below, as you can see it's all sealed. I suppose you can add an additional switch in one of the blanks but more complicated to get the wiring out. Anubiszed might have more of an idea as I believe he has taken one of these apart.

Not easily... That control panel is a series of pressure pads on a circuit board. Already looked into that.

I'm sure there's someone out there who could reverse engineer and create something that works, but that will be more Yen than it's worth.
