I believe you are correct. They had the computer world and it's circuits fed with voltage from the computer itself, and then you had the old school 12v world which would have all the regular starter interlocks and the rest of the body wiring. That's the way they did it in the beginning.

 

thanks for the info ct i'm going to try to post up the blueprint. i hope this works it'll be my first

OK, light-green wires, one end goes to the speed control amplifier I can't see the diagram on the right well enough to determine the other end of that Circuit 511 light-green wire.

This shuts off the cruise control if the clutch is depressed, and this switch exists only when cruise control is installed.

The switch that interrupts the trigger to the starter solenoid would be in the red/light-blue-stripe (Circuit 32) circuit from the ignition switch START position to the starter solenoid S terminal. When an automatic transmission is installed, it's called the Neutral Safety Switch.

Whether there's another switch that talks directly to the computer (ECM) I don't know, but I've never investigated an error 67 before and nor do I have any 1985/86 wiring diagrams or EVTMs.

Good job on the pictures in the post! You're getting there... as you're seeing, providing large documents can be a challenge.

 

your correct and thanks for showing me how to post pics although im new at using the site i'm an old retired mechanic at heart.Thankyou so much for your help 511 goes to Exterior lighting. Turn & Emergency switch

 

This circuit comes out of the computer on pin 30. Problem I am having is finding it in the diagrams coming from the computer on this truck. Do you have the correct computer in this truck as far as you know? Code 67 means different things for different vehicles, and if the wrong computer is in the truck, or a tranny swap has been performed, you may have some loose ends so to speak here and there.

 

I don't have that information because i'm not the original poster i beleive that hopsing69 is the person to ask however from what i see in the blueprint 511 goes to the exterior lighting turn emergency switch from there 511 goes to the stoplamp switch on the brake pedal support then changes color at the emergency warning flasher to red white 383 it then goes to a fuse (F13) and changes color again to 37 yellow where it splices 4 ways 1 & 2into the ignition switch 3, to a junction block which leads to a fuse link where the wire color changes again to Dark Green and then to the Starter motor relay. 37 yellow also splits again just after the junction block and goes to the Accessory Safety Relay. since the blueprint covers all models of f-150 for the year 85 I believe it that not all these components may exist on a certain vehicle because of the different options that where available at that time as well as engineering changes (factory changes to the blueprint) to correct some problems that may have occured. For this I would need to look at the 543 Charts to determine if a change was implemented and by whom. The 543 charts are an internal company blueprint of the whole manufacturing process of the Vehicle or engine, in perfect order from start to finish showing job by job in order on the assembly line,these charts also show how to install the part a picture of the part and the persons name who authorised the revision, at the end of the model year these charts are supposed to be destroyed,so as never to see the light of day.

Thanks Dort for posting the diagram. I did not get to work on the issue until Saturday and someone has removed the switch and the rod. Going to the wrecking yard today to see if I can locate the parts to put it back like it is suppose to be. What a mess.

 

Franklin2 As far as I know it is stock and not had anyone mess with the computer. This truck was bought new for my great uncle. It spent most of its early years on the farm. After he died it just sat up for 3 years. I don't even know where the computer is located. I suspect it is under the dash on the passenger side. Pin 30 I will keep that in my notes.

 

You're welcome Hopsing69 I hope it all works out for you, we are all here to help and if you need any more help just post away

 

In your diagrams you should have the computer hook-ups. None of the diagrams in the previous posts show that. In 85 you will have a diagram with a computer for a inline sithis was a computer controlled carb setup) and you should have a computer diagram for a fuel injected 302. The 351w and the 460 were still carbed in these years.

The computer diagram will be a long rectangle box with lines coming out of it. The diagram I have in the back of my Haynes doesn't give pin numbers though. And it is not showing a wire going to the clutch or tranny. It does show what you previously posted, but that's not the circuit we are looking for.
