Thanks stumpy. I knew folks more informed than myself would chime in. Just seemed that the one wire for the neutral safty switch was all that needed to be attached. Might I ask why it will not work? Rooster comb? And where can the O.P. and anyone else, get a new one? I have several old ones but as I use those trannies I might find I need one or two myself. Worse comes to worse I will just bypass it, but my luck I would forget and start it in gear or something dumb like that.
