Tom;
If by chance can you go to a GM style switch? I attached a link to a picture of my ped box with the switch in it.. It is very simple and easy.. KEM PART NUMBER EG-1072. $ 5.84...If the parts store by you doesn't carry KEM parts they should be able to cross it over for you.. I attached a link to a picture of mine.. I just drilled a hole in the front of the ped box and installed a small grommet then fed the wires through.. Mine works just fine. I also have the Haywire harness too... Hope this helps you out.. BTW you can use the same switch to make a clutch safety switch using your neutral safety circut..
