Hey guys,

I have run into a little problem with my 2007 4X4 Ford Ranger Sport with the 5-speed manual transmission with the manual windows and door locks.
Basically I bought a 2007 4X4 XLT Ranger parts truck with an auto trans that has the all the power options with cruise control and the plan was to remove the wiring harness from the parts truck and convert my truck over with all the buttons.
Well, to my surprise in 2007 Ford decided to delete that clutch pedal position switch electrical connection off of the Automatic in-dash wiring harness. I know the 2006 and older auto Rangers always had that plug taped up out of the way.
So my first question is question is … How hard would it be to wire in a C.P.P.S. into the auto wiring harness and 2. Is there a way to trick the PCM into thinking that the clutch is pushed in so I can start the truck?
(I know option #2 isn't the safest, but I'm never going to try to start the truck while it's in gear.)

Any advice would be greatly appreciated,

Sincerely,

Brian

 

The deletion of the CPPS harness actually happened much earlier, as my 2003 did not have the clutch pedal wiring, and I had to add it to my truck when I did the manual swap. Unfortunately it was over six years ago so I don't really remember what wires needed to be tapped into, but I do remember there were around six or so, and it wasn't too complicated. I do believe I had to either move, or completely remove at least one pin in one of the firewall connectors. I HIGHLY suggest you buy the factory wiring diagrams for your truck and spend some time comparing the auto and manual wiring. The factory diagrams are very easy to read, and at the end there is listing of every single connector on the truck, and it shows you each color and circuit number. It's one of the best purchases you can make when doing stuff like you're doing.

Yes, I think 2002 was when Rangers got 2 separate wiring harnesses in regards to manual or automatic, prior to that there was 1 main harness with a clutch switch connector under the dash and an automatic wiring harness was added and plugged into it, if vehicle was going to be an automatic, so it didn't "just hang there" unused

For your conversion you will need to swap over the SJB(smart junction box) and the whole dash wiring harness, and also the instrument cluster and engine Computer, they are a "matched set", so both Rangers need to have the same size engine

SJB is the "Body computer" and it runs the door locks and windows, like GEM did in 2003 and older Rangers

 

^Good point on everything being married together, had to do the same thing when I did my manual swap and put in the new computer. I had to get a computer that came with the matched PATS key so that I could start the truck up without issue, otherwise I would have had to get the dealer involved, and that's not even a guarantee that they would be willing to do it on a truck that was modified like mine.

 

Hey FordZilla,

Thanks for chiming in … I actually remember you doing that manual transmission swap because I gave you the driveshaft out of a 2005 Ranger because you let me store my 2004 Ranger in your back yard and you gave me a lot of your auto parts that you didn't need anymore.
I remember seeing that extra plug if it was a 4X4 on like a 2004 but if it was a 2-wheel drive then you had to wire one in.
I just assumed since it is a 4X4 then the plug would be tucked away like the 2004 - 2006 … but you know what they say about assuming.
I came across an article on here that said :
"Make sure you read up specifically on what Ron is talking about. Also make sure you read specifically in Trepaul's thread about the DTR and connecting 3 wires together. You have to complete the park neutral circuit. Connect TN/RD, PK and RD/WH wires together. This allows the ignition circuit to be closed when you turn the key. It also allows 4LO to be engaged with clutch/brake pedals pushed in. You need to have that clutch position sensor plugged in. Ron's right, 2001's have the harness wired up already. It will be plugged into a dummy plug right near where your clutch pedal is on the knee pan.

I was also wondering if the truck would just start up by installing the automatic harness but I don't think It would because I will be using the Manual Trans P.C.M. but if I'm wrong please let me know.

 

Thanks for chimming in Ron … Not to sound like a smart a**, but I'm not doing a auto to manual conversion. My truck already has a 5-speed manual trans. I'm just adding the power windows, door locks and cruise control.

The only thing I need to get off of the donor truck is the S.J.B. for the power windows.

 

I should have known it was you, there aren't many people willing to do what you're doing. haha.

 

LOL … Yeah, It's not for the faint of heart that's for sure.

 

Can anybody tell me if my truck would start up if I just installed the automatic in-dash wiring harness in place of the manual trans wiring harness making the truck think that it's an auto and it doesn't need the clutch pedal to be pressed in to start?
I obviously would need to push the break in to start it and that would put the safety feature back in place.

 

No, I don't think that would work, because computer doesn't have the auto trans software, manual trans computer will still want to see the clutch pedal down
Auto trans computer wants to see Park/Neutral from DTR sensor

Have a look at this diagram

 

Hey Ron,

Thanks for sending me that diagram.
I have now decided that I'm just going remove the C.P.P.S. (It's 6 wires) plug and wire it into the automatic wiring harness.
I'm sure that I could close the circuit and trick the manual trans computer into thinking that the clutch is pushed in, but that would be kind of dangerous.

 

It was worth it to wire in the CPPS for me because I never have to worry about the truck being in gear. I never even think of it.

 

Update: I ran into a mystery while I have been messing around with these 2007 2-wheel drive in-dash wiring harnesses and 4X4 wiring harnesses.
Can anyone tell me why there is an extra PATS plug taped up and hidden out of the way on the 4X4 models and not on the 2-wheel drive models? (I'm hoping Ron can chime in on this one)

 

I do see there are 2 extra wires for PATS on 4x4s, look at fuses 10 and 33, it has w/4x4

Same on the cluster diagram
But maybe its just the Splices are different in a 4x4, i.e. S122 and S223

Also just as a heads up, I see a "Door Ajar" light connection from cluster to the 4x4CM?
Not sure what thats all about, I would assume it would only effect 4Low, but "they" wouldn't want you shifting to 4high at 50mph with door open either, lol

 

Yeah, Ford does the weirdest things. You also notice that they do a lot of extra work and design a lot of parts differently for no reason. It sounds like the engineers at Ford have way too much time on their hands.
A prime example of this is the 2-door extended cab rear step bar brackets being different than the 4-door extended cab rear step bar brackets. Why not just have one design for both cabs? I did notice that the rocker panels only extend all the way around on the 4-door models. Could that be the reason?
Another strange thing I noticed is that on the 2003 and older Rangers (with the coil spring front suspension) + the 2004s that were made from 09/03-12-03 they have a engine mounting bracket that is more narrow on the 3.0 Vulcan engine. On the regular 2004 + Rangers they have made the engine mounting bracket wider and have eliminated that 2.5 inch spacer block. The reason know this is because I was trying to put a 4.0 SOHC into a early 2004 frame that had the 3.0 and it wouldn't fit. Then I finally realized that I had to remove that 2.5 inch spacer block so the wider 4.0 would fit. It was a PITA because the only way you could gain access to the nut on the bottom side was to remove the coil spring.
