Got a strange issue, had a Google but found no info....

Fitted a LED light in the side step of the van (Sliding door), there was no light originally. I've taken the feed from the rear courtesy light (Permanent live and switched negative).
Both wiring looms for lighting have been unplugged in the rear, one switched -ve will be used for the interior lighting when the roof is replaced the other was redundant, hence putting step light to it.
Now the side step light comes on when the front courtesy goes off, and visa versa? This happens if doors are opened or van locked (whenever the interior lights are operated using doors etc) :confused:

Any ideas on this???

Cheers

...... also fitted a LED bulb up-front (CANBUS error free), not sure if that has anything to do with it? If i remove it, the rear light doesn't work at all!? :confused:

The courtesy lights are controlled from the BCM, not simple +ve and switched -ve like old style courtesy lights.

Look for these two wires a brown/red and a red/black in the connectors (should be in the pale green connector) under the left front seat. If you have these try connecting your step light across them as that should be the correct circuit for the sliding door step light.
