pulling wires 5.7L Vortec

Well I can't activate my old account after the Hack so I got a new account so I will use this thread to document my v8 conversion.

Currently this is on hold because my fiancee is driving my 97 Chevy which be the donor. We have ordered a new Subaru legacy and are waiting on delivery.

Plan is to use the trucks engine trans xfercase with the ECUs out of the truck. I guess this is a good time to say that I work at the Subaru plant in IN and have an EET degree so I feel plenty comfortable with wiring diagrams and general automotive electronics systems.

I will purchase a JB conversion SYE for the 243C that is in the truck. I know the electric activation isn't the best but saves me cash for now that I will be putting into a D60 for the rear. Heading towards Dynatrack but Currie isn't out yet. I know I could build one but I want an ARB so I can't regear cut and install that in a JY axle for much less.

Anyways I will get some photos of the current situation up soon.

The hold up will be work getting in the way, I am currently in Mexico for work over a weekend that I could've used on the Jeep. So I hope I can post the information that might help or inspire someone else to tackle a big project on their own Jeep!

Like I said here is the current condition. I put a new Trans in the truck about 6k ago and it is running great. It will soon be time to start getting parts. Oh yeah also bought an Hobart MVP210 because after the motor swap and the axel I want to do some cage work.

Thanks Joe but I found most of the important threads I was following and this one is linked to a usable email account.

Thank you Jim, it was the only way the fiancée was getting me in the suburbs. I've had 4 vehicles in there before. I think it's going get very crowded soon.

Since this happened today, I am itching to start the tear down on the truck. I work at the plant so I'm very proud that my Mom and Fiancée are driving vehicles that I have engineering responsibility over.

Thanks Que! I look at your threads often.

So the brown Santa dropped off the engine mounts and radiator. Which motivated me to clean the fire up a little. Didn't take a before but...

Then I looked over at the truck and said my life's motto F- It. So I stared the tear down of the truck.

Got to the point of almost yanking the drive train when I remembered I need to unhook the exhaust and fuel. I'm off to Mexico for an unknown time so no progress will be made anytime soon.

Also spilled ATF all over the place. Good news is that the oil is nice and red.

A couple wiring tips I can offer...
1) Buy an AllDataDIY.com subscription for the donor and your YJ. That way you can see which Jeep wires to connect to which GM wires. I know wiring too, and it made the job a LOT easier. Print out the pages you need for the days job, etc.
2) I completely removed the underhood YJ fuse/relay box. I used the GM underhood box only. Since the YJ has mainly large amp fuses under the hood, it was pretty easy to move those functions to the unused large fuses in the GM box (GM fuse positions for HVAC, heated seats, power windows, etc.). The Jeep underdash box is still there, just fed by a large GM fuse or two now.
3) I had to have the GM PCM flashed by a 3rd party company to remove GM's VATS and to eliminate a lot of the body oriented OBDII codes, like 'fuel tank pressure low', etc.. I also eliminated the after-cat O2 sensor. I just left the minimum to make the motor run right.

Thanks Don, I'll check it out!

Has anybody welded their motor mounts with flux core? I have a MVP210 Hobart and was wondering if I needed gas. I have never done flux core welding so I obviously will practice first.

You have a 210MVP why not just use gas? Either will work. MIG just has no slag.

Mine were done with .030 flux core on a HH140 along with everything else on my Jeep. Flux core actually welds hotter than using shielding gas, so I've been told.
