Subject: Re: E30 Wiring Info

Anthony,
About a week ago, I installed a factory E30 alarm in my '91 318is. To put it plainly, it wasn't a fun job. It works perfect, but it took a long time due to
primitive instructions. Anyway, I have some info that will be helpful:

1. Leads to Central Locking Unit are Brown with a red stripe and Brown for ground.
2. The ignition wire is hot wire is located on a plug on the underside of the steering column. The plug is actually 3 plugs integrated into one. The main plug unclips from the steering column, and when you separate the 3 smaller plugs, it's the only red 8 gauge wire. It goes straight through the firewall to the fusebox.
3. From the way I understand the door trigger, if you connect your door lead from the alarm and splice in the original brown/violet door lead, when the door opens, this the original lead sends power to the interior lights.. thus completing a circuit and setting off the alarm. It all depends on what brand alarm you have though... If you have any other questions, you can write me at Abuck_at_us.ibm.com.

   Good Luck,
