nice work Billy! Just linked it to my thread in quicklinks.
This is exactly the info/diagrams that I will add to my pdf. However, mine will have more color ( ) and will cover both the Sym I and Sym II conversions. I will also add some notes on the reverse wire (Thanks Lee) and the CAN H/L (for Sym I only).
you might want to revise your pdf. A better part# for the pin for the SAT tuner T8s connector is 000-979-009 vs. 000-979-018. Lee made this discovery last month...and has made all the changes in his pdfs...and mine via www.nsxjr.com.
