Seems like we are running out of options?? Could it possibly be the brake light switch? I kind of thought we ruled it out earlier but I'm just wondering.

Well...if they cause the fuse to blow, they might be malfunctioning. Sorry.
I assume the TDC is for the tach. On the page where the diagram is, it says for locations go to 217. So you go to 217 in the manual, and it says "TDC Amp...in cap of diagnostic connector...202-2" so you go to page 202, look at pic 2. It shows a pic of the left side of the engine.
I think the diagnostic connector is the round screw cap. I never had any call to mess with it. The book says the amp is in the cap.
I'm running out of ideas to suggest. If it's speed/motion/rpm related, then that may be a loose or chafed wire somewhere on the F12 branch. Since the F12 is the switched fuse, it's possible that someone hacked into it for a aftermarket radio or something.
