Tony,
Excuse me for a slow reply, I have been flat out fighting with my spine disease for a few days.
The links in my signature will take you to a comprehensive "write up" in the Transmission Group and/or to the Latent Solutions installation wiring diagram via the Group or from the Transmission section in "my garage" and also, Suprastick install and Hybrid transmission install in my build threads.
I have tried by p.m. to answer a few of your questions, nevertheless, should all of the above writing and pretty pictures not convey it, I can't see the point of me writing it again?
At this juncture of confuddlement, the way forwards is to contact me and interrogate me by talking in old money and connect the dots that yet haven't.
