I haven't been around much lately because I've been busy cramming data into my old brain. I've got a line on a '91-'93 Tbird donor with a 5.0 HO, and it's the swap I've been looking for on my sig truck. I've been crossreferencing pin locations between my computer and the '88-'93 Mustang A9L computers. I have enough info to make the swap work, but in my search for info I ran across an article about "pin 41" on the A9L. The guy says it is for an electric fan, and gives a schematic for using this to control the fan. However I can find no other info to back his article up. '88-'93 V8 Mustangs did not have electric fans. If anyone can give me a link to any place other than fordfuelinjection, I would appreciate it. Hope I'll be doing this soon! Thanks.
