Hey Don, welcome to FordForums!

I do have the answer to your question, but unfortunately it's saved on my hard drive at home. I get off work at 6 pm, so I'll post the info on here after that.

Later,
Ben

Ok Tim here you go, I got this from Sven Pruett at Vanir Technologies. This is for a 4.0, but it may work with the computer on your 3.0 (if, by guessing from your other posts, you do have a 3.0)

Hope this helps!
