Ahhh.. that 'speed controller'. I had no idea it even existed. I just figured everything was in the module in the dash. That's a great link, to the pdf explanation, on your site. I found another one on lincolnsonline.com that shows a similar replacement procedure for this assembly. It was for a 2001 TC and in the same general vicinity (left side of firewall), so I'm pretty sure that is where I will find mine, a 1994. thanks again!
