I don’t see where the power feed should be for the blower. I see a red/yellow wire coming off ground, but not a power line or a plug. Again the Haynes doesn’t provide that level of detail. Also does the blower opening closest to the clutch pedal attach to anything? Thanks!

Wrong side of heater control box!

Sorry for the photo orientation

The black wire is to be connected to the earth wire which lurks under the dash area, the green one from the blower motor goes to the switch, and the other terminal on the switch must be fed from a green/brown live which comes from the ignition switch via the fuse box. 

 

Get yourself a wiring diagram - plenty on this forum.

Originally the black wire is as above, the wire from the heater motor to heater switch is green/yellow and the power wire comes from the fused live to the wiper switch and is light green/orange.

 

It is in the Haynes manual in the wiring diagrams.

 

The opening closest to the clutch pedal is for the fresh air intake hose which connects to the air distribution box in the right hand wheel arch.

Thank you. Now I can see that the black wire in my photo is connected to the switch, which is incorrect. This goes to ground as noted in posts above. The second terminal on the motor switch is for the GRN/Y wire that goes to the wiper switch but since I'm positioning in a mostly and empty shell with no wiring or switches in place I need to imagine where everything will be. Cheers.

Noted, and I have a Haynes manual. I just went through the wiring schematic and noted the major components.

Does this ductwork look familiar. Awfully cramped quarters to route ductwork to the front wheel well from the blower box.

That goes on the under the wing behind the wheel. the small holes goes to the dash vents in the corners of the dash, the one with the studs attaches to the inner wing and the big hole goes to the big hole in the front of the inner wing

Fantastic! Thank you!

Do the wires going to the on/off switch need to be oriented a certain way? After nearly two months working on various assembly bits I’m ready to install the heat exchanger in the car. I determined that I better have just about every other interior bit including wiring harness before final heat blower fitting. The engine will be refitted soon!

The heater switch makes and breaks the circuit between the battery and the heater motor so it makes no difference which way round the wires are connected to it.

[rokemester]

Fantastic. Thank you I was hoping that was the case.

[rokemester]

Just want to put a final comment on this thread. Thanks for the great advice! When we connected the battery all systems were go including the blower motor thanks to you!!
