Rear lights

[Christopherr]

Hello chaps,

My vans just failed it's mot on lights interfering with one another. When my fog lights are on you can't see my brake lights because they are the same bulb? It's fine with my lights on and brake lights because it uses the 2 different filaments as normal but when my fogs are on it's using the same filament as my brake light uses. So I guess he's wired the fog light into the brake light?

Now the bloke before has chopped all the wires off at the back of the lamps and put them back together at some point for some unknown reason which is really helpful! I'm really sh*t with wiring so I don't even really know how to go about this?

Any help greatly appreciated as I need to get this sorted asap

Also if anyone has a wiring diagram for rear light cluster that would be super helpful

from memory which is not that great lol, brake light is in the middle and fog light is at the bottom, he has prob had a bad earth to the lights [quite common] and tried to fix them himself

Van is 2002

Yes fog lights are supposed to be at the bottom

Hmmm maybe, he's certainly not helped me out

The reason the plug was chopped off is the light cluster connectors corrode and sometimes is easier to cut the plug off and add the plug from a mk7 maybe both sides have been changed and one wired wrong or there's a bad earth that will give you disco lights

[Christopherr]

Ohhhh right, why not just put another plug on the same? Any idea what colour wire the fog light one is and where abouts it should go in the mk7 plug? Il try gets some pictures up later if the helps. All other lights are fine and In correct place

Not just the plugs the little pointi things on the light that they plug in to go furked too
I just solder wires on to metal bit s on the plastic thing that goes to the glass thing with a Villanueva in it

I've just sorted the rear light clusters on my 2002 T280 as they were more disco that MOT-able...

The connector block at top of both bulb holders were corroded solid & had to be cut apart. I got hold of a pair of replacement bulb holders (eBay, £10-odd, cheap & nasty but did the job). Soldered a heavy earth cable onto the pressed tin common earth on each bulb holder, fed it through a hole drilled through the tin & plastic, split it & fitted a push fit connector and crimped eye to the end which goes direct to the earth stud in back of the light recess - apparently bad earth connections is the cause of many lighting problems.

Then soldered short cables to each of the remaining 5 connector pins at top of the bulb holder with half a push fit connector on each. Chopped the knackered connector block from the loom and fitted other half of the connector to each of the loom cable ends (these needed a good clean as the copper was black); connected everything up and its good to go. I got the wiring from a Haynes manual but was easy enough to check which was which with a multimeter / continuity tester from each loom cable end back to earth while a mate switched things on & off / stood on the brake pedal.
