HI Off Roader: I thought I communicated fairly specifically what my question was. I indicated that I had both the service manual and the actual parts manual for the vehicle - that I knew what the part was but that I wasn't sure what is was called -- I've seen it called the ignition module but that terminology is disputed, I've seen it called the ICM, the ignition transistor, power transistor -- I've seen links and places where it was for sale --- I've also seen contradictory information that exclude this part (as I've commonly found it online) from being compatible with my vehicle which is why I asked about iterations (possibly errors). Coupled with about 2 hours spent prior to posting searching the forum for a specific reference I'm pretty sure I did my due diligence to show I wasn't looking for a free ride here. Can you suggest how I could have gone about this differently. If I've overlooked some obvious reference or step I'd love to know as I have great respects and gratitude for peoples time and assistance here including your own. Many Thanks (And thanks to all so far for their assistance).
