Good call. It's the power wire to the control unit, which is orange in US built '85-'87 GTI's, '85-'89 Golf's, and '88-'89 GTI 16V's. The orange wire connects to fuse F20, then via a yellow/white wire to a load reduction relay #8. > Furthermore, it is not listed in any of the wiring diagrams in the Bentley.

On an '85-'88 Jetta cruise control, the Bl/W wire goes 2 places - to a 4 pin connector T4 under the relay panel, and to what is called the "cruise control induction sender". I'm afraid you may be hosed. It sounds like the control units are different between the Golf and Jetta applications, in that they use a different signal, or possibly 2 signals in the case of the Jetta. See page 126 of the current flow diagrams section. You may be able to tap in to the speed sender directly, if the Jetta one sends the same type signal as the Golf unit. --Holland [email protected] San Jose, CA
