Ford Wiring/Electrical :: 1997 F250 HD Manual Trans - Cruise Control Inopertive
Apr 17, 2017
1997 F250 HD 7.3L It is a May build so is mainly 1996 parts. Came from the factory with auto transmission but PO did manual swap. Truck had factory cruise control but never worked after the swap. I found clutch safety switch missing so installed that and now it works as far as truck only starting with clutch in and other pins ohm good but it didn't fix the no cruise issue. All the diagrams I can find are wrong so I am stumped.
Horn works and steering wheel brushes appear to be functional.
Brake switch has 12V in and out so I think it is ok.
Brake switch on master cylinder has power in and out so I believe it is ok.
All brake lights work since I read that diagrams don't show it but they are somehow tied into the cruise.
I believe the issue is in the clutch safety switch (CPPS) wiring as I only have power on one wire however my colors don't match my Haynes or online diagrams. Also, no where can I find if this circuit runs on hot 12V or ground. Some wrong diagrams show hot 12V coming in on the light green wire from the brake switch but others show a hard ground on the red/Blu wire.
Most diagrams say I should have red/LtBlu, Red/LtGrn, LtGrn, Gray/Yellow. I actually have Red/Blue, White/Red, Tan/Blue, White/Brn. The White/Brn has power coming into the switch.
The connector for the automatic transmission column shifter is disconnected and the shifter was removed. I read that this needed to be jumpered to the tan/blue wire after a conversion on the CPPS but only on 2002 and up trucks so I don't think this affects me. That plug is for overdrive cancel.
Looking for a good diagram for a manual shift, diesel cruise control circuit that shows my color wires on the CPPS? I have had this truck 2 months and have fixed everything except this and will be making a long trip soon so cruise would be nice to have functional but I am stumped.

I am trying to find out if Ford's cruise control has gotten crappy, or if mine has problems in my '06 F250. When I set the cruise, it goes about 3 MPH above what I set it at, then drops to about 3 MPH below, then it eventually stays where I set it. That is until I come to the top of an overpass or other small grade, then it is back to about 3 MPH over again as I reach the top and level out, then going back to where I set it.
The cruise control in my previous Ford trucks (83 & 91), as well as my 82 Mustang, 85 Lincoln, wife's 97 Toyota and the 2013 Chevy rental I just had, works fine. Where you set it is where it stays. Of course going up or down a steep grade, they all are going to lose or gain speed.
Anyway, I have taken the truck to the dealer twice for the cruise control. The first time is when I got the truck in '08. They replaced something else non-related, and said that would fix the cruise. It did work marginally, as the fluctuation was +-4 MPH before. I just took it in again before it goes off warranty, and they said the cruise is operating normally. So, there's my story. Is this normal, or is something wrong?

I have an 89 f250 7.3. horn has not been working for the longest time the relay clicks but still nothing. It doesn't matter weather the key is in the on or off position. I know it might be a grounding problem because the cruise control does not work any more (even though recently it was working just fine). I didn't see any bad fuses.

F250 6.8L .. So Ive read a lot of posts about intermittent cruise control issues. I understand that the most common failure is the brake switch on the master cylinder. My concern is that I am unable to run the cruise control self test I keep reading about. Does this test not work on my model year. I have tried even when the cruise control is working and still the cc light does no come on.

Looking for wiring diagram for the older Ford cruise control switches. I'm wanting to add an aftermarket system but use the factory switches. It's for a 99 ranger with the steering wheels like the mark 8s, older mustangs, explorers, and many others, had.

I have a wire that i think belongs to my Cruise control and I can't find out were it connects. It is dark blue/green stripe. It is in a wiring bundle with the oil sending wires ( two wires blk/w and y/o ).
I also get a code ....no sig from clutch neutral switch.
I just got done putting new heads on my little 2.9 and can't wait to use this as my daily drive. These two wiring issues are keeping my truck from running well enough to drive.

Where is the cruise control amplifier located on an 85 F-150? The Chilton manual just says "behind the instrument panel". No pic or further description. Just looking up from the bottom of the dash I see a "black box" with 2 wires going into the top of it located just between the steering column and the wiper switch.
Is this it?

I recently changed out the power boost canister for the brakes on a 1990 f-150 2wd. It was successful but now i have no cruise control. I double checked my plugs, all good. I checked my brake lights, all good. brake pedal seems fine and completely raised when not in use. i looked for a fuse and can't find it for that system, seems odd. it's not in fuse jct under dash, can't find a fuse jct under hood, seems odd also. No check engine light has lit.

1991 F250 Supercab Diesel 4X4. I made a mistake while wiring up my trailer lights and ended up grounding out my brake controller, frying it. Along with that, I popped a couple fuses as well (1, 5 and 9 I believe). Replaced all fuses and got my signals (F/R) back at least.
Here's what's NOT working/messed up:
*Brake Lights
*Cruise Control
*Rear ABS light comes on a few minutes after driving.
*Front hazards work, not rear. When I apply the brake, the hazards pause in the on position.
I've tested the brake switch on the brake pedal (Green/Red and Green) and it works properly. So, current is obviously not reaching the rear brake lights.
Another note. The truck is wired with a 7 pin plug in the bed for a goose neck trailer. It also was wired to a 6 pin on the bumper. I replaced the 6 pin with a 7. The signal/brake pins on the plugs (both) and also not receiving power. What's the next thing to check?

I have a 97 F250 HD. Wiring the rear tail lights. When we bought it the had cut off the wires going to both sides of the rear lighting assemblys and I was wondering what wire went to what i have the left turn signal working just can't seem to get the brake/back up light to work on that side and i can't figure out how to get the right side going either.

I have a 2001 F250 with 7.3. We swapped the auto for a zf6 manual. We left the auto's shift position sensor tied to the frame and left in neutral. I did install a pcm from a manual transmission pickup. Also have the clutch position switch hooked up. I have an Edge Evolution CTS2 reprogrammer, and on the display the gear indication always shows P. I suspect that is why my cruise doesn't work. For interests sake, I tried manually adjusting the shift position sensor through all gears, and the reverse lights come on when in reverse but the Edge's display always shows P. My question is with a manual transmission, how does the pcm know that it is in gear? The only sensor that I am aware of is the reverse sensor on the zf6.

Well I've had her just 1 week, used, and today I turned it on and the power is out on the A/C n Heater /Fan Control ASSY. It worked the last 900 miles from FL to OH. And today worked this morning, but 2nd time I got in the truck today there was No Lights in the Air Control Assy. I didn't get an Owners Manual, so what fuse to check.

I did the diagnosis,on my non working cruise control on my 2000 f250. The cruise light came on when, I, depressed the off switch and turned key on. I depressed on switch,cruise light came on.
I then depressed the resume, coast, and set switch, as described in the diagnostic procedure,suggested,and no light came on. Do the switches for the cruise control are bad.
I have checked the fuses at the power distribution box under the hood and checked the fuses under dash,all are fine. I just replaced the switch at master cylinder, as it was leaking and it had the recall switch replacement, too.

I have a 1997 F250 that I am fixing up. The issue is this... The dash lights now flicker off when I place the transmission in Drive position. I can slightly move the slack in the gear selector and the lights come back on. When the transmission is in Park, the dash lights work correctly. Not sure why there is some type of switch to control the dash lights buried within the steering column?

I am planning a swap in an Excursion from the automatic to the manual transmission.
How will I need to modify the wiring harness to make sure everything still works?
Things I can think of that will need addressed:
Harness for the brakes (Neutral Safety Switch?)
Harness for the clutch pedal
Cruise control harness differences?
Back up switch wiring?

I just bought a hard to start 1990 F250. Per the board, just replaced all 8 glow plugs with Motorcraft. Still wouldn't start (it turns over but will only start if you use either). I attempted to install a new BWD brand (Borg Warner I believe) glow plug connector relay today...I removed the old no problem, but am unsure what wires to plug where....the only connection that I'm sure about is the blue wire that works the WTS feature...it plugs in easily but I don't know if there are other connections that need to be made or not? All the wires run from the posts and into the bottom of the unit.

The Trans will unlock while driveing for a few seconds then lock back up and drive fine, it seems to be worse over the past couple days. It is no different cold or hot. I also noticed the head lights dim and the voltage on my scanner drops to around 12 volts when the trans disengages. When it is not acting up it drives and shifts perfect.
I have checked a few grounds that were visible and cleaned battery connections. There has to be a wire harness or ground that I am missing some where that is bad?? The misfire code has been fixed, not related.
