ive heard about this in the tuner ricer cars before, is it possible with these trucks?

 

Not easily.

 

well what would i need to do?

 

I honestly do not see the point of this mod.

 

The EEC harness currently in your truck has 60 pins but the OBD-2 version has 104. One solution would be to replace the complete vehicle wiring harness with one from a '96.. but you still have to add all the extra sensors and devices that your powertrain doesn't have but the OBD-2 system requires. Another possibility is to get a donor harness and splice in only what needs to be added to make it work in your truck.. leaving the chassis wiring alone as much as possible. Unfortunately the engine and chassis wiring is all integrated together in the newer truck so this is not a simple task.

 

i was just curious man its not like i said im die-hard about doing it. just wondering. not like im asking you to help me do it. curiosity.

 

so basically, its rewiring the entire truck and then adding more sensors and crap...

 

And crap, yes

 

I was just wondering if there was a reason for doing it, no need to be upset.

It just seems like alot of work for not much if any gain.

 

Havent seen this thread progress and there was a serious question that needs to be answered!
I have a 93 351w SD bronco E4OD tranny, and I have to do OBDII conversion for a motor I pulled.

I got lucky, and have a donor vehicle with 351w MAF OBDII, wiring harness, fuel harness, and EEC all pulled. I have began to notice the differenced between the SD and OBDII MAF system; there is a massive jungle of wires under the OBDII trucks dash, with a data link, another computer box, and far more wires going to the instrument cluster.

I am wondering what I need to salvage from the donor vehicle, to make its motor run like stock in my bronco.

The reason I am doing this, is the donor vehicle has the f4te block which I have confirmed to have the roller cam. It requires an OBDII system, so I have to swap it all over. I need to re-pin my auto 4x4 in the bronco, and rear power window into this new PCM, but i ahve no idea how to go about that and would really appreciate some help on this.

I have asked on FSB forums as well, and there are plenty of people doing OBDI swaps, but I am looking for someone with experience regarding the OBDII specifically; and they rarely came in broncos (96 only year to have them, and last year for broncos), so I have a feeling most the people who have experience with this swap will be on the f150 forums.

Any help would be much appreciated! I am looking for a PCM layout for my 93 SD 351w bronco E3OD, automatic 4x4, and one for the 104 pin 95 f150 MAF OBDII E4OD, manual 4x4 so I can begin re-pinning to accomodate for my broncos rear power window and automatic 4x4. and last but not least, should I pull the tranny as well from the OBDII vehicle due to any OBDII sensors? both trucks have E4OD but I know OBDII has more sensors in some places

 

No you don't.

My 94 speed density, OBD I, EECV-4 is a F4TE block & roller cam.

Going to OBDII gains you only real time monitoring of some functions. (to go with the mass-air)

Some where on this forum is a fairly detailed change over a member did, but he never gave a very good ending for it. (several years ago)

We last heard that he was trying to get the crank position/damper sensor to work.

 

No you don't.

No it doesn't. My advice is take the easy way out on this one and use the existing EFI system in your Bronco. All you got to do is remove the upper intake on the new motor and strip all the wiring off, then put that motor in your truck and connect it to the existing '93 wiring harness. The only mechanical differences between these that have any impact on this swap are the EGR system and the distributor drive gear and in both cases you just need to use the components off the '93 motor. That's it.. done.. it'll run like it was always there.

 

Talk to William Vose, aka 85lebaront2 on this board. He's made an 86 into an obd2 460 truck.

 

Hey all;

So i have a 93 f350 that i bought from a guy that had it and this model didnt have turbo yet so later on he did a motor swap with a 94. the truck has an OBD2 but i was told its a dead OBD2 that it has power because of things in the dash and what not but not because it has any motor function. The truck does have an OBD1 under the hood. How can i get the OBD2 to function so that i can flash the truck with an Edge performance chip?

Thanks!

 

You can't.. it would require an OBD2 PCM that your truck doesn't have.
