I'm not sure what you mean by "long plug." Our daughter has our Jetta at college right now, so I can't check it. But I believe, like with all VWs, that there was a connector at the end of the wiring harness that plugged into each tail light bulb tray.
If the previous owner cut off the connectors on the wiring harness, then if you're very, very lucky a VW dealer might still be able to get hold of them. Otherwise, you're probably forced to jury-rig connections with spade connectors or something. I just can't visualize right now what the bulb tray connectors (sockets) look like.
Oh... I think you'd have to pay someone to take Altezza tail lights off your hands...
Thery use a few different plugs on each side, which go to different things. On the driver side, some wires that feed the passenger side pass through the bulb tray. On the passenger side, the third brake light connects to the tray.
Your best bet is to go to a junkyard, get the trays and lights, and cut the harnesses from the junkyard car (remember to leave as long a wire as possible), and just match the colors.
Black (or Black/Blue, I think they updated it for Mk3s) Reverse
Gray/Red right tail
Gray/Black Left tail
Black/Green and Black/White turn signals (cna't remember which side is which, check the front bumper lights, they're the same colors)
Thanks. The original plug was still in place on the drivers side. I few wires needed reattached, but was basically there.
The passenger side I got creative. I took the bulbs with sockets out of the Altezza lights and using long screws, drilled through the socket and into the back of the taillight itself. It works... not pretty, but works.
I will try to source a passenger side plug and hook that up, but with inspection due, I had to get it working.
I had trouble figuring out why the third brake light was not working. Somehow the prior owner though two ground wires running to the third brake light was a good idea
The parking light wires are not green. Gray in German is abbreviated GR. (grau) while Green is GN. (grun). Same reason yellow is GE. (gelb) and red is RO. (rot).
They fixed it in the Mk2 bentley but lef tthe Mk3 bentley full German
Doh, you're right. Good catch, thanks.
Those abbreviations aren't standard German; they're unique to VW wiring diagrams. Even though I know German, I always get confused whether "gr" stands for grün or grau... even though the legend is right next to each wiring diagram.
I'll bet the Germans get confused too, because German VW wiring diagrams also have the legend next to each diagram.
I corrected my post above.
At least I got the black/green correct for the right turn signal!!
