yes 5.4l, its a 2000. build date of 11/99

 

did you have any problems getting the pcm to communicate with the truck? I have everything done for my swap but just cant seem to get the wiring right. Ive spent countless hours trying to figure it out and have all the pin out charts and wiring diagrams for the v10 pcm and 4.6 pcm ( thats what was in my truck) to cross referance the wires if needed. My odometer will not read anything. Ive been told once i get it to show a number thats when im ready to go. however i still cant figure it out. Do you have any sugestions since youve already done this?

 

You may need to double check that the 4.6 wiring will even work with the 6.8 pcm. Everything that I know of says that they use the same communication busses so it should be exactly the same as i did. Which was move the associated pins from their v8 location, to the location that the v10 shows them in. As far as your odometer not showing numbers, that usually goes along with the VSS. Is the car at all driveable, or is it still in the build stage. Also, do you have PATS removed, or a PCM that doesn't have PATS on it. If you can't get it to work, you need to look into the wiring of the transmission, because that sounds like an obvious change you will need to make. I don't think that the v10 computer is going to talk with the 4.6 transmission, but I could be wrong. Either way, take your time, and just make sure you follow your wiring from its actual location (i.e. from the sensor plug) to the computer plug.

For anyone else trying the swap, now you can see where I said that the wiring is the most difficult part. You really need to take your time, and make sure you make a chart that shows what pin moves to what location.

 

but now we know it's possible

 

According to the pin out charts all of the data bus wires are the same color and are in the correct location. The computer does have pats but it won't let you reflash it until its getting communication with the dash. Atleast that's what I've been told. I am how ever thinking all my problems are coming from the transmission wiring. Which I don't quite under stand as its a manual trans. I will go over it again tonight and see if I can figure anything out

 

Pats does have to talk to the instrument cluster, key, ignition switch and ecu to all work right. Really the transmission wiring is only going to things like pressure switch, backup lights, VSS....stuff like that. As far as all of your engine connections, the only things you are really changing is stuff like injector locations, COP locations, and stuff like that. What part number of PCM are you using. What model vehicle and what trans is it setup for. This could be your problem as well.

 

Trav2210 did your speedo and odometer work after the swap?

 

No, thats due to the VSS wiring. The VSS on the v10s are driven from the same exact pn/location VSS, but is wired different. I'm am currently working that problem. I belive it to just be some wire changing at the ECU. The original v8 looks to only have one connection for the VSS, whereas the v10 has two.

As far as working, they do work until the transmission shifts into OD and then I get a VSS flag in the ECU, and the odometer lines out and the OD light blinks on the shifter. Should be simple wiring

 

Snowman, are you trying to hook a V-10 up to a M5OD? If so, I don't recommend it, it's a light duty transmission. You need a ZF if you want a manual V-10.

 

the pcm is set up for an excursion with the 6.8, I am not to sure what transmission it is set up for. I did find out that my GEM module was not getting power as it gets its power through the vehicle speed servo which was not pinned into the computer. I am going to go through the pins again and make sure I get all the pins for the trans in place. The truck did originally have an auto trans but was swapped out with a 5spd about a year ago before the motor swap. It ran perfectly fine at that point with no reflash. Since it is still wired for an auto trans i feel as if this is where my troubles are coming from, as there the only other thing i have touched. I am still not getting any communication at the obd2 plug however. Thats where im thrown off. I cant see the trans pinnouts having anything to do with communication at the obd2 plug. Either way im stressed to the max. This is all in my plow truck of coarse and its supposed to snow friday ( I had obviously planned on having this swap done A LOT sooner but we all know how life is and the things that come up)

 

The excursion ecu is going to have PATS in it, so that is more than anything, the first thing you need to address. Nothing will start/turnover/run without getting that disabled first.

 

Right. Ive towed the truck to ford to have it reflashed for the pats twice now. The first time I wasn't getting anything at the plug no power no ground no data. Second time had power and thought I was communication with the pcm. I was wrong. The motor will turn ver but I'm not getting any spark or injector pulse. I believe that's because of the PATS. However the wiring diagram shows a starter interupter module. If I was getting a theft cde would the motor even turn? According to the diagram no. Just as you said. Honestly I'm at a total loss/ complete brain fart/ can't handle any more wiring diagrams and pin out charts. My only other thought is to try a different pcm?

 

The motor will turn over but will not do anything but that till the PATS is disabled.

I have my PATS turned off in a custom tune. Because I'm running a Lightning PCM in order to control my 4R100.

 

will the fuel pump turn on with the PATS system active? also trav what pcm did you use for your swap? theres not much more i can mess with in the wiring to try and get communication at the DLC. unless I make my own DLC under the hood to have the pcm reflashed. But as I stand right now Im not even able to turn the pats system off. Also i forgot to mention earlier that the truck is no longer in the build stage its ready for break in once i can get it to fire up.

 

PATS is your problem. no fuel and no spark is what it will do when it is engaging. The security light is driven by the cluster, so it will start and run with it lit. you are going to have to have PATS disabled, or switch computers. I will get you the pn of my ECU, which off hand i know came from an f230-350 with the 4r100. Some of the 250/350s do not have pats. I found this out at the dealer when he checked to remove the PATS and it wasn't there. I think this may be part of your problem. I would avoid creating your own DLC. you can call ford for a listing of ecus without pats, and i will give you the pn of mine, but beware, there are a whole bunch of PNs out there. It took me a while looking at ebay and such until i found mine at a junkyard.

Also if anyone is going to attempt this as well, I have a bunch of extra parts laying around like intake manifolds, sensors, and stuff.
