The car in question:
A few months ago I attempted to install the GE remote entry system in my 1988 325is. Central locking was working fine, but the remote would only unlock the car. I gave up for a while but I tried again recently, but something went wrong while I was working on it and my central locking stopped working entirely. I have checked the fuse. My interior lights are also funky, and I'm wondering if the problems are connected. I started digging around behind the kick panel and I have found many loose wires and strange plugs.
I have been using the wiring diagrams on e30zone to try and clean this up, but I need help from more experienced people.
This is what I'm dealing with:
Central Locking
Nothing happens when I lock or unlock either door or trunk. No clicks or anything. It used to work fine.
There is evidence of previously installed remote entry systems. The GR/BU wire is interrupted by this large black plug, and I don't know why.
Interior Light Relay wiring
The driver door jamb switch doesn't seem to do anything. The interior lights only come on when the passenger door is open, and the trunk light has never worked. I'm not sure if the trunk light wiring is self contained or if it connects to the Interior Light Relay. There is also a second Interior Light Relay up by the steering shaft.
This strange bundle of wires is hooked into the Relay through the BR/VI wire. The white plug on the right has 3 BR/VI connected to it. One comes from the relay and the other connects to this bundle, while the top runs towards the door jamb switch (pictured further down the page).
The 4 cut wires include:
BR/VI that connects to white plug with the relay
BR/BK that connects to white plug on the left and appears to run with towards the back of the car.
GR/VI with wire tap
BRown with wire tap
This is the BR/BK wire that runs under the carpet and towards the back. (on the left in the last pic)
This is behind the driver door jamb switch. There is a BR/YL wire connected to the switch, and the wire with the spade connector is GR/VI. It was connected to the second prong on the switch.
That GR/VI wire gets wrapped up with this BR/VI wire which is plugged into another BR/VI that has the grey/white striped wire that does not connect to anything. The BR/VI connects to the Interior Light Relay.
Here is the extra relay. It has the same numbers as the Interior Light RelayIt even has a bracket on the back to hook onto the metal triangle with the Central Locking Unit:
Other wires
I have no idea what these wires do
This plug with red wires is coming out of the firewall, but is obviously cut. It does not look factory.
The flat white plug on the left is not plugged into anything. I can't find anything behind the kick panel that would connect to it
The small white plug with red/black wire, and the BR/BU wire on the left are loose.
This is the plug on the far right in the last picture. The wire has been cut.
I would greatly appreciate any help with this mess!
