Have indeed !
Me and
@gstuart fitted a Revotec one, full kit from Revotec. Being honest the instructions are a bit s**t, Gary fortunately is good with electrics and we ultimately decided to plumb in a separate loom for the fan as splicing into the loom can open a proper can of worms. Separate cables behind the dash and through the bulkhead into the engine bay. I bought the separate fuse from Revotec (which ultimately we didn't use as Gary preferred to use a separate fusebox we fitted into the battery bay). We also used the separate on / off switch from Revotec which allows me to be in control of it as opposed to relying on the thermostat supplied (fully adjustable).
The wiring and working out the electrics were by FAR the biggest part of the job, but a top bit of kit and works a treat. Really pleased with it, and I'm still offering big thanks to Gary for his expertise ! No qualms in admitting it wouldn't have happened were it not for him !
