Alarm / remote central locking question..
I have already read through the other topics regarding this topic, and none seem to be able to help me with my little situation.

I'm trying to connect an alarm/immobiliser to my E36, but have already spent over 5 hours trying to find the right wires.

The first problem is, being an AUSTRALIAN delivered E36 with the steering wheel on the right hand side of the car, the looms pictured in other threads (from the US) are not in the same place in my Aussie car, so finding the right wires has been basically impossible.

The wires I can't find are:

1. Door switch (for interior light). Apparently it is Brown/Grey with yellow rings, and should be on the door loom. Well, its not there. I cant even find a switch that it should earth at.

2. Indicators/turn signals. Used my circuit tester and cant find any pulsing signals.... I've decided to just tap off the front indicators near the headlights and back into the cabin. Gotta connect my M3 mirror signals while i'm at it anyway...

and finally.... the big central locking question.

Ive got 2 wires coming out of my alarm unit. One says LOCK, the other says UNLOCK. Both supply a NEGATIVE output pulse for 0.8 seconds at 300mA maximum. Do I need relays? Do I need diodes? Is is as easy as connecting the LOCK wire to the lock wire on the driver's or passenger's door loom? I'm assuming I wont be able to deadlock the doors without using the key.....

This is the point where my wallet says "dont risk trying it yourself."

Jap cars are so much easier when it comes to re-wiring..... I really should just take it to a sparky and pay him to do it..... I'm competent, but just not 100% sure.

Hi everyone. Been away for a while. Miss me?

M3, I changed my rear door switch a little while back. Little bugger's shaft snapped.
IIRC, the wire to it was Brown with White stripe.

Can't help with the indicators or locking at this point as I've never sucessfully found a wiring diagram for an Oz E36. (The bentley manual PDF floating about didn't look right.)
Find me one of those and I'll:
A - be grateful
B - try to help

I've never had much confidence in auto-sparkies myself. My experience has been with the type who know stuff by wrote, but nave no clue how electricity really works.

And where exactly IS the door switch?

Is it part or the catch mechanism (below the door handle)???

Jap cars normally have a pin on the pillar that the door closes against to de-activate..... but there is nothing like that on the BM....

Yeah, the Bentley didnt help me either. My car has bits that match the Canadian diagram, and others bits that match the Euro...

I have a BMW specialist about 4km away, but might need a bank loan to get it sorted thru him. :eek:
