There is a lot of unclear information about Golf/Jetta 2 pinouts so we decided to publish the information for these old cars here free of charge and so everyone can use it in projects and in repairs.
Golf 2(Jetta 2) had two generation of cars, the first was CE1 and had two sockets in the car – black and white, and the second one, CE2 – white or black single two-row 28-pin(14+14) socket with 2.54 spacing.
CE1
Below is a pinout of CE1 version of wiring with two versions of the naming.
Plugs are assembled from two parts but it’s not easy to notice it.
The plugs part number:
White:
AMP 926505+927294
Black:
AMP 926505+927293
The plugs are slightly different in their appearance.
Important – the crimped pin part number:
000979115E
It is almost impossible to buy it separately and uncrimped, unfortunately.
White connector
