Homer Posted February 17, 2008 Share Posted February 17, 2008 The wires that go to the heater control unit (3 orange plugs) had been chopped off the loom, today I was adding the plugs back in from a spare loom, but encountered a problem with the centre one. It has two wires on both the loom and two on the plug which are exactly the same, I'm not sure which wire should connect to which. They are both pink with a black stripe. I'm not sure if anyone here has any experience with these wires as it's not a very common thing to have to mess with.. Any ideas folks?

MA70 Posted February 17, 2008 Share Posted February 17, 2008 One wire connects the 'A/C amplifier' to the 'Rear window de-fogger' button on the 'Heater control switch'. The other connects the A/C amplifier to the 'A/C ambient temperature sensor' I can send you a copy of the wiring diagram if you PM me your email, or tell me how to post it on the forum.

You can post jpegs on the forum, but not sure what format the file is in. If you could email it to [email protected] I'll try and make it available here. Thanks again - I wasn't expecting anyone to be able to help on this one! Quote Link to comment Share on other sites More sharing options...

SimonB Posted February 18, 2008 Share Posted February 18, 2008 The complete electrical manual is on mkiv.com, that has wiring diagrams of everything (albeit for UK/USA spec). Dunno if that's the same one you're talking about, but if so it's here:- http://www.mkiv.com/manual/1995_electrical_manual/index.html Quote Link to comment Share on other sites More sharing options...
Sean1933 Posted February 19, 2008 Share Posted February 19, 2008 If you cant work it out from the diagrams then just do a polarity test between the bare wires and rear w/screen heater or ambient temp sensor. Quote Link to comment Share on other sites More sharing options...
