8 month struggle to get this car right. Just tested the lighting circuit. Everything works but the rear markers and tail lights. Signals work reverse lights work backup lights work but no tail lights. I have a schematic and there's a connection at T4 and I can't find it. Any help would be great. Also, whats this connector to the right of the CE panel.

It's a 84 928 s. Like I said, back up, signal works. But no rear or side markers or tail lights. I know it's at that connector I just cant find it. It may well be the connector that's hanging by the CE panel but I can't find the control unit where it 's supposed to go.

For my later car, T14 is an 18-pin connector. Listed location is on the right side above the engine controllers. Your picture is of a 12-pin connector.


In your WSM, sheet 12 in the 1989 wiring diagrams lists the connector numbers, number of pins, location description, and the location coordinates with a reference diagram. This may or may not help you with your earlier car, but might offer some hints.

I think it's that connector in the pic that connects to the lamp check module. I may have unplugged it when removing the parcel shelf. Ran out of time last night. Now I just have to locate the module.

From what you reported and the picture offered ,it shows the lamp control module connector,
the lamp control module is not plugged in,
once this is plugged in the rear lamps should work as well as the brake lights
NOTE the module is bolted to the right hand end of the right side parcel tray.
NOTE if your getting rear lamp warnings also make sure the side marker lamps are good,
and the white 2 pin connectors on the hatch floor are corrosion free

I was wondering where the module was since I pulled the parcel tray that explains how it got disconnected. Thank You
