Here is a link to the wiring diagrams. http://bbbind.com/free_tsb.html

We do not have this deatiled information. It would be in the Ford factory service and repair manual which is not free to share on the Internet. You can get a used one here.

if you look on the distributor you will see the large connector for the mudule bolted to the side. The spout connector will be within inches of the module connector.

Hello, For the brake pedal it can be a Master cylinder problem. You would need to replace the Master Cylinder and flush the brakelines as the lines may be full of rust. It would not hurt to check your brakelines for signs of staining and wet spots.

The clutch on your model may have a return spring that is missing or weak. There is also spring tension on the throw-out bearing. You may need to adjust the clutch linkage to compensate for wear on the clutch disc. You want to adjust the freeplay so there is 1/4 to 1/2 inches of freeplay before the throwout bearing is touched.

Also check your pivot points for the pedal levers under the dash. Check your transmisson and motor mounts for movement which could cause binding. When you adjust the clutch there may be an Interlock switch for the starting circuit. Make sure this switch is working freely and that the clutch pedals' return is not held back because of this switch.

That about covers everything that moves on those two pedals. I hope my solutions are very helpful and you get your truck fixed.

Sounds as if you brake light switch is not working or adjusted properly,check for voltage to the switch then depress the brake pedal and make sure you have voltage on the outward side of the switch if ok check the bulbs at the taillight assembly

Hope help with this (remember rated this post).

Try depressing the clutch and the brake pedal at the same time while moving the dial to 4x4?

need the engine and whether its internal or external regulator and your fax or email

Powerstrokes do not have an accelerator cable. All fly-by-wire. Possibly the rheostat in the foot pedal going bad. Are the gauges functioning on the dash?
