OK, need some advice. I have a 1986 300E, 102K miles, in good shape. Fixing it up for my 14 year old to have when he turns 16. I bought a cheapo ($16 from Hong Kong) keyless entry on eBay and installed it, works great. I want to have the lights flash and the horn honk when I lock and unlock. I started looking around the car and got to the factory alarm under the passenger side front carpet which was disconnected. I read that most people disconnect this because it is problematic.
The alarm box is a MB 126 820 08 26/BAW 845 Z 0000 unit. It has two plugs, one 8 pin (009 545 17 28) and one 14 pin (010 545 86 28). I traced that on the 8 pin plug pin 3 lights up the side lights and pin 1 honk’s the alarm horn under the hood. I can wire the keyless entry box wire for flashing the lights to both pin 1 and 3 and I should get lights and horn when locking and unlocking.
My question is does anyone have a schematic of what all the pins do on both plugs? I now am thinking about a full fledge after-market alarm and want to use the pins on those two connections to wire it up. I am sure they have the features an alarm system would need are in those two plugs.
Thanks in advance
