Aftermarket remote central locking

[chris]

Our 1994 L400 does not have remote locking but it has central locking. For $16.00 delivered to my door (in three weeks), I got this remote central locking kit from ebay. http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... &viewitem=

If you are thinking of doing this, the wiring is accessible from the drivers side footwell kick panel on the right. (others have done it by the lock ecu under the dash above drivers left foot) Drivers side footwell right side - remove the one screw and then the panel and you will see the wiring harness leading from the footwell into the door. The connector (C39 on the wiring diagram) is hiding in a hole covered with a rubber flap. Pull it out.

The green wire with white stripe when grounded is lock.
The red with green stripe when grounded is unlock.
Also in the harness is 12V heading to the red door light. This wire is a red with black stripe.
There is a ground point near the harness in the footwell.
The module fits nicely behind the footwell panel when replaced.

The wiring diagram in the kit was junk. So, black was ground and red was power (it had a fuse). A brown and a white go to the indicators to flash when you lock or unlock. I didn't do that. The locks are loud enough!
That left another white and a brown and a blue and a green. In the case of this kit the white goes to lock and the brown goes to unlock. I tested continuity between each wire and the ground while pressing the button on the remote (and giving the module power) to figure that out.

To make life easier when making the connections, you can unclip the harness and pull it through to the door hinge area. It gives you more wire to work with. Make your connections to the module wiring harness and then feed it back through into the footwell. I soldered but I think scotchlocks would have been easier.

It works! Thanks to Bullwinkle for the inspiration! I hope this helps someone.
