Cummins Conversion Update
Mine will probably end up looking similar. I'm going to run completely new wires for the battery and starter wires, since both batteries will be located on the driver's side. I'll just keep that one trigger wire off the relay and probably use some welding cable to have custom wires made. My plan is to run one large cable from the battery over to the starter, and cables off the starter to the relay and then one to the alternator. Running one from the alternator to the post on the starter will let the alternator supply power to the batteries but keep me from having to run two large cables across the top of the radiator.
Checkin on the progress today and it's looking good. I'm starting to decide if this is something I want to do in the future, cause there isn't enough cash to do it now.
Was going to let you know, there's a guy here in Great Falls, Montana that has been doing these Cummins conversions for years and is pretty well known. His name is Ken Krause at Auto World.
He did the swap for a guy with an F550 in Cali that was featured in the April '07 (I think) issue of Diesel Power Mag. It is a white supercab dually with an aluminum flatbed. It is quite a sight as it was back up here for the past month or so getting a new common rail installed. I stopped by the shop the other day to pick up some parts and they had it out putting the final touches on it. OH MAN WHAT A SIGHT!!
Anyway, Ken helped design the Destroked adapter plate as well as the new Painless wiring harness to mate the new motor to the existing Ford electronics. The man's a wealth of knowledge when it comes to these swaps.
Can't remember the website off the top of my head. So if you want his contact info, let me know and I'll get it to you or anyone else that would like to talk with them.
Looks awesome and can't wait to see the end result!

Got a few more things done in the past couple days, but nothing worth photo worthy. Mostly small things that need to be done or planned for.
I went through all the old electrical stuff I had added that was specific to the 7.3 and removing it. Stuff like the 6-gun I used to monitor stuff, TC lock switch, EBPV switch, my LED's to monitor those two, and the switch I had to choose between oil pressure in the HPOP res or the block. That took some cleaning up of wires under the dash too, but it's pretty tidy under there now. The only thing that sucks about that is now I've got a bunch of holes in my dash where I had switches, LED's, gauges, and the DP chip installed. I'm sure I'll find something to fill those spaces though...maybe with things like switches and LED's for water injection or nitrous?
I also un-routed all of my other sensor wires back to the hole in the firewall so I can hook them up to the killer weatherproof harness Jim sent me. He sent me a 4 wire harness that has a weatherproof connector that is going to make hooking up the gauges very easy and very clean too.
All the battery cables have been pulled out as well, since I'm going to have to get custom cables made. I also found a guy who has all the splice connectors and some extra welding cable that I'll be able to use for the battery cables. This guy is also pretty good with sheet metal fabrication and is going to help me get a battery tray made up, since both batteries will be on the driver's side and facing 90* from how it sat from the factory.
I picked up a bunch of different sized wire loom today too. I want this thing to be clean, and look as close to factory as possible when I'm done. It's amazing what covering the wires with some split loom will do to clean up an engine compartment, not to mention offer a degree of protection for the wires.
I went by the AC shop to confirm that they'll be able to splice the lines together. No problem there. That's going to have to wait until the engine is in the chassis though, since he obvioiusly needs to know length of the lines and orientation of everything. The lines will have to be a little longer since the compressor on the Cummins is on the lower corner of the engine.
Also laid out my plans for fuel system plumbing and will be ordering all the fittings and lines here in a little bit. I'm going to go ahead and hook up the y-block I've got, right out of the filter, since I plan on adding dual CP3's soon. I figure I may as well lay it out now and just cap off one side of the y-block instead of having to change it up later.
I also layed everything out for the PCS controller, so I could start to get a pretty good understanding of it. I think I'll try to get the harness run for it tomorrow. Got a few questions for PCS, which I need to talk to the tech line about. If I get my answers, I should be able to get everything hooked up with it tomorrow.
So, that's where I'm at right now.
It doesn't hurt to use the stuff on water hoses and even brake lines. A little abrasion resistance can go a long way toward reliability insurance.
I'm really enjoying reading about your progress, Jeremy.
Awaiting fire!

Oh, and Pop, I think you might have your J's confused.

I actually should have plenty of hands and help around here to get that engine in place. However, if you felt like driving down to check it out, you're more than welcome to.
