On your CSS question: yes, it may happen that the CSS is losing its "vitality" with age (how do I know this?). The way I checked mine was to see how far I can pull out the rod by hand without throttle linked (what is the travel of the rod), mark it with oil marker and then see how far the rod is pushed by solenoid with throttle attached. If it pushes the same distance and it is holding - the CSS is ok. Then you would need to regulate the rpm with the nut and counter nut on the rod. Refer to Linkage Tour (adjustment) in Technical Manual Full Members zone.
Wiring: what you ask is about auto transmission wiring. You may not find it. I will PM you on this as this may be a sensitive area, you are a Full Member.
I hope your CSS is not blown. In case it is - please search the forum, but I am not sure if we have a reliable way of fixing it or buying it for a reasonable price - I mean to avoid living on beans only for two weeks...
