Have just rewired my Mk3 ('72) with a loom from Autosparks - all nicely matched up apart from the heater. I have a green wire with bullet connector off the
heater fan but nothing on the loom to connect it into. I've compared with the old loom and there's nothing there either! Everything has matched up on the
two centre spurs.
All I do have left behind the centre dash is what appears to be an extra connector for instrument illumination, red with bullet connector, and the radio
feed.
Not clever enough to work it out from the wiring diagram (Haynes) - frustrating as I thought I was quite careful removing the old loom. Can anyone
enlighten in simple english! Thanks in anticipation!

Peter,
I see that you posted this some time ago, but with no responses to date. Maybe you have now solved the problem?
From the fuse fed by the ignition switched supply (white wire), I'm sure there should be three green wires going into the loom. These feed the reverse
lamp switch on the gearbox, the heated rear window switch and the heater motor respectively.
The feed to the heater motor should emerge from the loom roughly in line with the heater installation, and this is connected into a double bullet
connector joiner. The joiner is used to split the power feed between the B terminal of the voltage stabiliser (for the fuel and temperature gauges) and
the heater motor.
In the case of the heater in my MK2, I found that I had to connect the power feed to the black wire coming from the motor, and not the white one shown
on the diagram (as far as I could tell, this was how it had always been connected). The white and green wires from my heater motor are connected
together (no such link is shown on the diagram). This leaves the green/yellow and slate wires for connection to the heater fan switch.
My replacement loom was bought some years ago from a company called R D Components, which I think was absorbed by Autosparks at a later stage.
Obviously, there are some differences between the MK2 and Mk3 looms, so I don't know if any of the above will help.
