Broke my Original heater switch a while back.

finally got round to replacing it.

Ordered STC4848. plumbed it all in as was and no bueno.

Noticed that the earth has nice and helpfully plastic coated. Handy Cleaned that up and all was good.

But my biggest query is - wiring scheme states as a 200tdi loom i should have green slate and green yellow for lives. I seem to have green and green red - it worked previously and continues to work but its a bit wierd.....

Green red should be indicator switch to left indicator - and that certainly doesnt come on when i fire up the heater

Greens just 12v.

Any ideas ? im not going to get particularly worried but it is a bit wierd no ?

Are they the same colours as under the bonnet by the heater.
Mine are green/yellow & it's an 85 loom
