The only blanking plate I see in mine is on the b pillar. You got pics of yours installed?

 

Mine has the two volumetric sensors, but no "horn siren." The alarm system just uses the regular horns. One of mine was dead so I replaced them with air horns anyway.
I haven't had any problems with the alarm going off unexpectedly, but I never use my sunroofs.
The wiring should all be there ready to go; as someone else said, you should be able to pick up two sensors from a dead truck. I think they are interchangeable.

 

If you can't find em on an D2's P38 R/R's had them as well

 

Interesting, I'll have to check if mine is there.

I've been drawing up plans for a custom alarm system using a raspberry pi and arduino. I spent quite a bit of time researching aftermarket options and they all look like junk or have stupid features like remote starting. Early stages..

I've also added the Mantec window guards for the barn door, cargo windows, and rear passenger windows. I'd like to fabricate a steel barrier between the driver seat and rear.

 

Are you going for a mad max Uber/taxi vibe?

 

Here are pics.

 

Thanks for the pics. I see all the wiring is there and i have to verify if the blanking plate is on the passenger side c pillar.

 

mine doesn't have the back one since it's a 7 seater.

 

Mine's a 7-seater.

 

Weird BC I went and looked at mine and didn't see any spot for it on the rear piece on either side.
