Cleaned up the back box today which was a nice little purchase from eBay

This will kill most people but couldn't decide where to put the switch so ended up on the bottom of the chair also got the car wires up and motors test run ready to work on rear exhaust on fitting the valves

would like to see the results with these. Video's would be great to hear the difference. I was thinking about doing these but haven't found the right set up.

Ash tray.

Use a pulse latching relay to turn the momentary pulse from the buttons used for the front/rear fog lights on a standard 3 series into a 2 position on/off switch is cleanest IMO. I did this for my laser jammers.

IIRC I got the pulse latching relay from baker electronics.

You can replace the ashtray with this:

I stuck 3 switches, a V1 display, a V1 remote unit, and a BT headset in there.

Just wait till the motors start crapping out and they get stuck open.

Hopefully they've gotten better, but my friend was swapping the motors out on his every 6 months or so a few years back on his WRX.

If you get a rear diffuser piece it will make the tips look perfect.

Anyway, how and where did you run the wires for the switch. as in how'd you get them into the cabin and what power source did you splice into?

My guess is to run up towards the transmission and up into the shifter assembly. From there you can tuck it under the centre console to where you'd like.

I thought I would add to this thread instead of starting a new one.

I ordered DHM cutouts and hope to get them added in the next few weeks. Has anyone tried to use the EDC button? I don't have that option, so it seems like a nice option. Also, does anyone know a good exhaust shop in the Atlanta area that would be willing to do this mod?

Bump..

Are there any other options like this, or is this the best one?
