Radiator fan over ride switch help wheres this go?

Hi all
trying to fit an overide switch for the radiator fan, can anyone shed some light on how to do this, idealy can any one show me some photos of where I need to connect the wires to the dashmounted swich please?

Thanks as always

Hi if you are using a heavy duty switch then connect a heavy duty wire to each of the two that come out of the rad temp sensor at the bottom, back of the rad or you need to use a relay across those two wires and then you need a power ideally from the ignition I think I got mine from the cigarette lighter socket and through the switch to the relay and on to earth. I originally just used the switch but it has quite a lot of load and the lightish weight wireing I used was getting hot.

Thanks for this, I have a heavy duty switch and cable so I should just attach the cables to the where the current cables go into the rad fan or am I looking for something else?

Thanks

I just spliced them in one to each wire as the rad switch can still kick the fan in if you haven't noticed the temp go up.

Being so dumb here, the Rad switch - where is it? any chance some one could post a pic so I can find it?!?!

Thanks

James

if you lay under the front of the van so you can see the back of the rad its the wires at the bottom next to the water pipe sorry for the dodgy pics it was only to show trhwe repair I had made.
