Td4 fbh

Hi looking to fit a timer to my fbh which will put the heater on for aprox 20mins Do you have to remove the nearside inner wing to get to the wireing I belive you have to put a postive feed to pin3 of the unit to fire it up I may use a remote unit to trigger the timer or mybe a clock Has anyone done a DIY set up on one of these heates

I've been having similar thoughts - you can buy 12v remotes on eBay for peanuts. I thought if I put a switch in Pin3, it might fire it up without the engine being on?

if you do a search its been done before...

if the engine is not running the coolant would not circulate through the engine or does the fbh have its own pump to do this i have a seperate on/off switch for the fbh as my outside temp sensor failed
