Help! 4 wheel ABS vs. 2 wheel ABS
I am in the process of fixing the truck that I wrecked. Originally, I was planning on swapping the cab from the truck that I bought to my old frame, however, once I started I realized that my original frame had a lot of rust and the other truck was almost completely rust free. That is what is causing me problems. The newer truck has 4 wheel abs while the older truck does not. As I am changing the motor and transmission over I am also having to do the brake system since I am converting from a gasser to a diesel. My question is: Will the 4 wheel abs system work with the diesel's PCM? Sorry for the long post, I just wanted to give a little background so as to describe the problem a bit better. Thanks, Mike.

You will need to do more research. Diesels also come with 4 wheel abs also. I would be inclined to stick with what came with the original truck. That way it will all match when you need to repair it.

I'm tempted to say "yes", but you need to do more research on the ABS pump/valve unit before you go ahead and do that. The diesel, with the hydroboost, might have more pumping pressure from the master cylinder, and the ABS unit might be different to handle it.
But again, I'm tempted to say "yes" - for a few reasons. The PCM will probably get a speed input from the ABS unit - which get the speed from the rear ABS sensor (VSS). That won't change between gas or diesel.
Gotta get into an EVTM to really check, and wait for some other guys to comment on this one.
Hang in there

The new truck is a 2000. It would seem as I get further into this the more problems that I run into. The newer truck had a V-10 that had some major issues, so I pulled that motor and am trying to put my diesel motor into that truck. I am wondering if anyone else has done this before, or am I leaping out into the wild blue yonder here? Any help/suggestions are greatly appreciated.

I can't recall that many major differences between the two years. The ford trucks weren't integrated enough as far as braking and control modules to cause enough problems. However, you may need/will have to swap a whole lot of harnesses to make it work right. I don't have access to my repair info right now, but at the very worst the abs can be worked out later.
