Thank you for all your advice, as long as the boss allows me back out into the garage, :-) I have been hiding in there a lot and ignoring her.
I will see if I can trace the wiring from the BOB to the plug and see if it has linked through to it, if it has I will note the pin number, am I correct in thinking that it goes from left to right from the top row ( the one with the most pins) as to look at the plug. I know that the wiring to the switches is correct as it is wired n/c and I have already checked that.
I did wonder if the BOB was not suitable for the mod, but I will know later this morning I hope :-)
I did try to search for another controller putting 6040S in the search box but nothing came up I was hoping to find one with a connection for switches.
I will get there,
