So I have a 1960 ford falcon, I just pulled the old 144 and auto trans out and put in a 200 and a c4 from a 1965 comet. The swap went well but I cannot get the starter to engage. I know that the components are good as both engines ran fine when pulled and I have done multiple test with a multimeter and test light.. I am convinced it is the neutral safety switch on the new c4. How do I wire the nss in the 1960 falcon that doesnt have wiring for it? There was no wiring on the old transmission so Im guessing that I need to run wires to the nss on the newer c4. I have searched a little but cant seem to find anything that helps. Wondering as well how the ford-o-matic safety worked as that would only start in P or N.
will not try to start in neutral, or any gear? have you traced back as to how, if nss is wired? tried to jump wires at starter?
"If" the NSS is good, power runs from "start" contact of the ign. sw to the NSS to the starter solenoid. NSS will have multiple positions with continuity, start in park, start in neutral and possibly reverse for back-up lights. Sort out the wires with a tester to find park and neutral.
