Highly unlikely it'll need a separate ECU.
Just tap into the relevent wires for each light (1 tail, 1 brake, 1 for each blinker), and go from there. For the earth, there's bound to be an earth point somewhere in the back of the car not far from the tail light wiring.
sounds unlikely, no issues putting a towbar on a mk4 so a mk3 shouldnt be a problem
Thanks for that however when I do install it
How could I tell if I need a ecu??
Should be pretty straight forward installing it. As for the wiring exactly as "umai naa!!" Said you can just tap into the relevant wires and wired it to the socket. There might be a oem harness for it which should be plug and play but I don't know whether they came from factory with a towbar
I've order my wiring harness with the cable today
Ill install it when I get it
I'm only worried I would damage my computer cause I didn't install a ecu:(
You won't destroy your computer all your doing is extending your tail lights, the signals won't go anywhere near your computer :)
Very doubtful this will happen, I really shouldn't worry.... i'm assuming the harness just plugs into the passenger side tail light? all should be fine :)Quote:

pretty sure with the mk3's one tail runs from the other? could be wrong though...Quote:

its a universal one so im gonna tap into the relevant wires
The Towbar guy said that cause its a european car i might need a ecu he said extra 110 bucks and if i didnt have one it could fck up the computer:( thats the only thing im worried about.
Pretty sure just for the mk4 onwards mk3's should be fine without it as we don't have very fancy electronics
Anyone know what colour wires I have to tap into??
Opened it up can't find which one is which
Got the wiring diagram but wasnt really good at school not to sure to how read one :(
From looking at the Bentley wiring diagram....
Black/Red = Left Brake Light (in the 6 pin connector on the left tail light)
Grey/Black = Left Tail Light (in the 6 pin connector on the left tail light)
Black/White = Left Rear Turn Signal (in the 6 pin connector on the left tail light)
Brown = Ground (in the left tail light in the 4 pin connector)
Black/Red = Right Brake Light (in the 6 pin connector on the left tail light)
Grey/Red = Right Tail Light (in the 4 pin connector on the left tail light)
Black/Green = Right Rear Turn Signal Light (in the 4 pin connector on the left tail light)
Hope that's good info :)
Thanks a lot for that almost done now
I just want to know which colour wire is for the number plate lights??
Looks to be a grey/green wire in a 5 pin connector possibly in the rear left light too.....
Any advice on having a towbar installed on a manual 2011 Golf Comfortline 118TSI in Sydney? I just tried contacting Carasel who put the bar on my previous car - a commodore s/w - and they said that "because of wiring problems they do not fit bars to VW vehicles. They need to go back to VW for reprogramming."
probably simply needs VCDS to sort any possible tail light errorsQuote:

This needs to be done by Volkswagen's diagnostic computer (or the various similar devices on the market).Quote:
