I just cut open a 401 passthrough as it was not working properly. It seems I MAY have made a mess of the circuit boards. Do I really need them or can I install a switch an wire it directly to the atty contacts. If so can you supply me with a simple wiring diagram? The 401 was an auto and beside being too hard to hit the thing was intermittant somehow.

I do have all the parts and might be able to reuse them if necessary.
