PCM wiring harness (how do I remove?)
I am trying to remove my wiring harness from the PCM of my 1995 F-150. Damm, I cannot understand why the darn think won't come off. I have turned the center bolt counter-clockwise for the last twenty minutes, and nothing is happening. Please let me know who this thing is fastened in there. I need to get it done early this afternoon so I can get the exact replacement PCM at the junk yard. Anyone with experience in this matter please respond! Steve

Just pull it off?
Subford: didn't want to break anything? I finally was able to get the numbers off it. I'll be getting the part today at a boneyard for 75 bucks, but damm, it's stuck there good. The question is, "are there clips holding it that keep it from wiggling loose?" I am asking that because nothing seems to give, although since this truck is 12 years old, it probably is on there tight. Please Subford, I wasn't looking for a "just pull it off answer". I know that! I was afraid I might break something. STeve

When I take the plug off I loosen the center bolt, it turns free for a few turns and then it starts to get hard to turn. I wiggle the plug and then the bolt turns free again and I keep this up until the plug comes off.
There is nothing else holding the plug on, no clips.
The PCM has two small nuts, one at the top and one at the bottom that needs to come off before the PCM will come out. Then sometimes it is hard to get it to come out.

Something is serious stuck!
Hello: It seems that something is seriously stuck. That damm center bold has been loosened, and at this point, the thing should wiggle out of the sucket. I have put almost 100 pounds of pressure trying to wiggle that socket loose from the PCM, all with no success. It's colder here in ohio, and I am not sure if the cold weather is affecting this, but I need to get this thing out. Should I use WD 40 or anything? Maybe a hair dryer to just heat the thing up? It seems as if the think was glued in the socket. I am not kidding when I say this. I may have to breat this damm thing out I am almost certain. Any advice from anyone who has struggled with this would surely be appreciated. I have the new (used) PCM, and I am anxious to install it soon. STeve

PCM wiring harness won't free up!
I have been trying to remove the wiring harness from my 1995 F-150 truck that goes to the PCM, but all is in vain. I have even gone as far as to break the outside edges of the defective PCM, but nothing is freeing up. The center bolt, which I have turned counter-clockwise to loosen, still doesn't seem to make a difference. I know that it's loosened, and I personally think that the problem lies not with the bolt, but somehow with the connector contacts being frozen in there. I am not kidding. Also, I spoke with the guy at the junkyard that sold me the brain board (PCM), and he said that there are no clips holding the PCM to the wiring harness. What I am to do? Is there a solution to this dilemma? Steve

Finally the truck runs!
Ok, no one responded, but that doesn't matter. Had to break off the cowling from the defective PCM in order to get it off. Yes, it was that tight on there! Anyway, it's official! The PCM (brainboard as the junkyard receipt wrote it as) was defective. And yes, the Actron CP9150 tester was the culprit. Going to Autozone tomorrow to give them the scoop. This has been a long week, but boy have I learned a lot about this truck! Steve

Thanks Subford!
Hey Subford: Thanks for all your help regarding your advice that my PCM was defective. The only thing you were wrong about (and it's minor) was the price of a used PCM, which I paid only 74 bucks for at a boneyard.
The damm cowling off of the old PCM had to be broken off Subford. I am not kidding when I say that this thing was not going to free itself. It literally took that much effort. Anyway, once I installed the new PCM, the truck ran sweet. It runs super duper now, and I hope that I can have all the soot cleaned out of the truck considering how much it built up.
A word to anyone listening. If your gear shifting on your automatic is suddenly hijacked, especially after autozone hooks up their Actron to your vehicle, then you can best bet you have a blown PCM. Thanks Subford and everyone that helped me get through this treacherous week. I couldn't have done it without you guys.
