Hello and thanks for using JustAnswer.I will try my best to help you with your question.
Does this E350 have an air bag in the steering wheel or just a horn button?

no it is 1992...can you email me a schematic?
Ford Mechanic: A. Penland, Ford Senior Master Technician, ASE replied 3 years ago
No problem. The air bag was an option in the 1992 E350 and the wiring is different.Below are the diagrams.

do you have a wiring schematic of the under hood fuse box that would show pin numbers and color of wire that powers horn relay
Ford Mechanic: A. Penland, Ford Senior Master Technician, ASE replied 3 years ago
Ford does not have one for the 1992. There should be a diagram on the side of the relay that matches the wiring diagram. There should be numbers on the bottom of the relay also.

so it should have battery voltage at the horn relay under steering column. What voltage should read at steering wheel for cruise control?
Ford Mechanic: A. Penland, Ford Senior Master Technician, ASE replied 3 years ago
There will be no voltage at the steering wheel. Only a ground circuit for the horn and the cruise control. Each cruise control switch sends a certain amount of resistance to ground back to the speed control servo.

Sounds good. I will be at work at the dealership, but I will get an email when you reply and I'll get back to you as soon as I can. It all depends on how busy the shop is.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.
