...as I typed it (in my sleep ), I dreamt what would happen, and I was right.

I promised a complete 'How To' on the FFOC site several months ago...

This is the circuit diagram:



The reason I say it cost a fiver, is because for ease, I build them on strip board. They also need to be complete sealed to prevent moisture/water getting in. I use heatshrink and silicon. Although only small pieces are needed, you have to buy enough to do several at a time !

If you want it neater (like the ones imported from the US) you need to get the plugs and sockets from a breakers who doesn't want the complete harness or sensors (or their damaged so he doesn't mind). They don't have to be blue ones as the polarisation lugs can be filed off the plug, and new slots cut in the socket.

I have some spare wired ended ones liying around somewhere if you don't mind cutting into the blue sensor wires to solder it in.
