Subject: relay for warn beep with motion sensor
Date Posted: June 04, 2009 at 10:49 AM

I am looking for a relay to enable the first stay warn beep using the DEI 508D. I currently use the blue wire only with success but having a warning beep would greatly reduce false alarm

This is how I setup the motion sensor in my 2002 VW Golf : [url=https://forums.vwvortex.com/zerothread?id=4414568]https://forums.vwvortex.com/zerothread?id=4414568[/url]

And this is the motion sensor's manual i'm currently using, I hope someone can help:

Thank you so much for the quick response, sorry im no electrical guy, not sure what you meants with those numbers

- Blue wire from sensor to RED / brown in harness (blue arrow shows location)
- Red wire from sensor to RED / black wire in harness (red arrow shows location)

Red to a RED, what's the red brown, black is correct blue via relay as shown above to a siren, your wiring is a bloody mess, I should have taken photos of an 00 Golf I did today, you won't find my wiring. Look to the right of your red and blue arrows, you can just see the ignition loom, go to a red wire, fused via 3amps. If I remember RED / black is the brake switch output to the brake lights.

yeah its a mess lol, but hidden by a clean trim panel posted_image

I can see how much of a n00b i am by reading your post, for example I am not sure what you said by fused by 3amps

Anyway, like i said, the motion sensor currently works fine but without the pre-warn beep, So I was wonderign if I could connect that green wire to a relay, and if so, which relay and how.

If I can figure it out with you guys, I will update my tutorial on the car forum here: https://forums.vwvortex.com/zerothread?id=4414568 . that way many MK4 owner will have easy instruction to upgrade their alarm with a fully working motion sensor
