"Hi guys, I am in need of some help, I have three wires that come from the transom of boat. Two of the wires are for the trim cylinders and the last is my delima, (Brown/white stripe) with bullet connector. I have search everywhere and still can't come up with a termination point. (Might be to put in base timing mode)?? Help"

"Thanks, That was a big help, it was a part of the manual that I didn't have. I have gone thru the troubleshooting for Thunderbolt V and it seems that I have a bad sensor in the distributor cap. I am going to replace and hopefully I will know if that fixes the no spark situation.. Will keep you guys informed.."
