Alright before anyone says REPOST hear me out. I checked on bmwe34.net and got the diagram for 92 and 1/2 which i had with the logo for prewired security system. So i hooked up my aftermarket alarm and got the keyless entry part working GOOD!! Now I wanted to use the feature that it has to flash the corner lights when the doors unlock. I was wondering which wire to use. The diagram dind't have one. So i was wondering another way i could make them flash (the alarm has -12 v outputs for those) and then theres the horn. does the prewired security system use the horn horn (one you push on the steering wheel for? or does it use its own seperate one?)


Thanks for any help

Use 2 relays for the parking lights , get them at the dash switch 2 grey wires right and left ( dont connect them together ) they will only flash outside the car not the instrument cluster.

+12v @ # 87 & 86
- 12v from keyless/alarm to 85
And 30 is the output to the parking light wire.

And the horn output is for the cars horn ,All newer cars 90 and up use -12v for the horn at the colume thats why its -12v output.

But bmw use a positive and its a pain in the ...

Those are on the relays you buy at any automotive retailer, 30A single pole, 7.5
I don't know if I did it right but I just used one relay and conected to a Yellow wire to activate headlights flash: one for close and two for open. But I don't know if there are any issuses with that one. It just looked like it could be more visible for me from the distance and the snow storm.
