Hi can anyone let me know where the below wires connect to.

At the moment when I turn the lights on with the ignition on the lights on the heater panel light & speedo lights up but the computer does not light up I have changed the bulb with a working one I have taken 2 pics one with the camera flash of so you can see the lights on the heater panel working and the other with out a flash on and it looks like the computer display is working but it is not. Just to ad the nothing else lights up like the cig lighter, rear ash try.

At the moment this is sitting on the glovebox side it has enough wire to stretch over to the drivers side not sure where it goes......

Image

This is from behind the trip computer just want to know if the yellow wire connects to anything

Image

The 2 wires next to the orange relay which are red with white trace & brown with green trace

Image


Looks like blue with brown trace does this connect to anything

Image

green with purple trace & a brown wire

Image

And last one any idea where this clips on to cant seem to find a place it would clip on to it is near some kind of ecu on the drivers side.

What model and age?
OBC has two lights in it - a bulb that fits in the back and illuminates the buttons when the panel lights are on, and a small white circuit board that slides into the right hand side, which back lights the display. This circuit board is now £60+ from BMW apparently, but the two small bulbs on it can be replaced for just over £1, if you're handy with a soldering iron.

Hi Brian

It an 325i convertible on a K plate auto. The car was originally a 318i but has now been converted to a 325i auto, The complete wiring loom from the donor 325i was fitted in to the 318i.

Hope this helps if you need to know anything just let me know.
