Does anyone have a wiring diagram for wiring up the caterham heated screen up.

Would have thought it would have one live feed and an earth? Might be worth wiring through a relay .

Here is the Caterham Wiring Diagram for a K series Car (up to 2006) : https://www.graduates.org.uk/docs/201626_EU3_wiring.pdf

No relay in the Caterham for the heated screen, fuse rated at 10A, but that is not to say that is good practice!

Aslong as the switch you're using is rated high enough, then you should be ok without a relay

That being said, personally I'd probably fit a relay

Fit a relay, you would be mad not to.

The cost less than £1 and isolate the circuit from the rest of the car's switch and feed wiring.
