I’m sure this is easy, but… fitting a new heater switch.

Post by KenT3 »

Hi
I’m been the proud owner of Ollie since August 22nd. We’re getting some minor electric work done and the auto electrician has gone off ill poor man.
I have a new heater fan switch to fit which seems to have more copper connectors than I have wires for AND I haven’t a clue what wire to put on each one.
There is a + terminal, I, II, III, IV terminals and a blue wire, a red wire and two grey wires that seem to be the one wire. So I’m guessing that may be the ones to go to speed terminal two and three?
Can anyone help
Cheers
Ken

Those colours do not match the "standard" switch loom colours.

Terminal + = black / red from the fuse box.

Terminal I = white speed 1

Terminal II = yellow / black speed 2

Terminal III = yellow speed 3

No listing for terminal IV.

There are separate wires for the heater panel illumination bulb.

Terminal 31 = brown to chassis ground.

Terminal 58b = grey / blue illumination wire.

Assuming you mean the main front blower motor switch.
1983 Tin Top with a poorly DF and 4 speed DT box.
1987 Electrics and a DJ engine.
Maybe one day I might get it finished

Thank you for your help here. I did think something was amiss with the wiring. I tried to make sense of it but gave up and let an auto-electrician sort it in the end.
