One question, though. If I test the purple wire contacts with the dual connector detached from the NSS, which result should I see with the ignition switch in the "on" position?
(a) Both contacts cold
(b) One contact hot, one cold
In my test today I got result (a).

Let's review just how the start circuit works.. Starting at the ignition switch - the "big" red wire feeds power to the ignition switch directly from the battery.. It's "hot" all the time.. Turn the ignition switch to "ON" and the red wire feeding the HEI becomes hot.. The purple wire coming from the ignition switch is hot ONLY in the start position.. That purple wire feeds power through the NSS to the "S" terminal on the starter solenoid.. The NSS is a simple off/on safety device.. It prevents power being applied to the purple wire going to the starter solenoid unless the transmission is in either PARK or NEUTRAL..
So to answer your question -- Neither of the purple wires are hot with the ignition switch in the ON position..
If your shift linkage has a lot of slack and wear, you're gonna have one heck of a time getting the NSS adjusted properly..
