Heated rear window wiring

[supercass]

I have a Lenham hardtop for my TR7 and have utilized one of the blank spaces on the switch panel for the HRW switch. All the wiring is already there as standard. The switch I have however does not appear to have a tell tale light and the plastic screen on the top of the switch through which a tell tale light would shine appears to be a very dark red colour and unlikely to allow much if any light through. It is a later type switch. i.e. to say it is a match for all the other switches. There is also no light in the push in connector that is in situ behind the panel. Can anyone clarify this for me? Where should the tell tale light be, what colour should it be, is my switch an intermediate type and incorrect? Thanks, supercass

I utilised the HRW part of the loom to run a different accessory and fitted an extra fog light switch in the panel to activate it. The white connector block behind the switch panel already had a bulb / tell tale light inside just waiting to be connected up to a switch. It's in a small recess at the top of the block. IIRC the whole block had a piece of factory fitted insulation tape wrapped around it to prevent the contacts in it from earthing.

It sounds like you're using a hazard switch if it has a red transparent panel. My fog light switch has an amber one. It's the white connector block that carries the tell tale bulb on my DHC, not the switch. As far as I know all the DHC's have this spare HRW connector block between the headlight and hazard switches.

Thanks for reply. It is definitely a HRW switch as it has the appropriate symbol on it. The light screen is very dark red, almost black. It appears as if it was intended to have a light but the back of the switch is different from the other switches with tell tale lights.What colour should the HRW tell tale light be? supercass

The light in my heated rear window switch is purple.

Mine is purple as well but its a pretty dim light.
