Hi Again

I never did find the ABS Box. Following a thread I found on this forum, I pulled the plug on the the rear axle abs sensor and took a ohm meter and it read zero ohms. I installed a new $15 dollar sensor and the dash light are off for now.

Is there a Ford E350 manual posted somewhere on the internet?

Thanks very much! You have save me a big bill at a Ford shop.
