|PrecisionPowder||If you ever want to do a diesel swap again in a jeep I recommend using a 1.9AAZ IDI TD motor. Its a mechanical diesel so you have no need to worry about the wiring. You can use the same trans adapter plate since both the newer tdi motors and the older idi motors all use the O2O transmission configuration. They are significantly cheaper, easier to tune, easier to make power on, a million times more reliable, and the swap time is a ton faster. I have built several big turbo volkswagen diesels, its nice to see them being used in wranglers once in a while|

There are a few more details to work out, but it's a success. A few notes:
The VNT 17 turbo is worth the few extra bucks if you have to replace your turbo, but not enough to warrant an upgrade from stock.
The air/air intercooler works ok
Air/air fuel cooler drops fuel temp by 30f
Stock VW fuel filter and fuel temp control valve works to recirculate warmed fuel to the engine, and keep the fuel cool.
If you have any doubt about a used engine, don't do this conversion unless you're prepared to disassemble/inspect/rebuild. This rule applies to any unknown engine really
Trust your gut instinct before you drop the cash; do it because you want this conversion, not because you want more economy. If you're already familiar with late-model VW, international, cummins, Benz, Isuzu, etc., then you know what I mean. You buy it because you want it

|Wondertwin1||I would definitely have no problem dropping cash and my wrangler off to you. I want this so bad|

|Alects||Those TDI's last forever! Seems like a fun project... Time to save up!|

Noble cause, I really like that. Why not make a small business out of it, I've no doubt there are a few dozen of us that'd deliver our vehicles and a check for you to use in helping vets recover. You could certainly sell the ones you're creating too...use the money to fund more projects?
Anyway, kick ass project with an even more kick ass purpose. My hat's off to you!

It is rumored the two major players in the conversion aftermarket (one having a deep Mopar connection) will soon have a JK system using the 3.0 VM diesel as found in the Grand Cherokee and RAM 1500.

|FXnut||I'd love to see a 5.0L V10 Touareg TDI dropped into a JKUR for your next conversion!|

First drive impression:
VNT-17 turbo pulls hard at 1500 plus rpm. I will look at a mod for the air box/MAF.

A9 Light Class 1 Diesel Cert
Above link to ASE for test registration. A new A9 Light Diesel cert is now offered. It is meant to cover modern electronically controlled full-authority diesels like the TDI.

Forgot to mention this very important component:
Suggest that the donor car engine build date be the same or newer model year manufacture than the recipient Jeep. For example, a 2003 model ALH would be ok for a 97-03 Wrangler.

Couple posters have asked about my (or somebody else) being able to do more of these conversions.
It's much easier this time around. I mean, there WAS NO DOUBT what had to be wired how in order for it to work. The challenge this time was packaging it up in such a way as to not look like a mess. It was important for it to be serviceable, as well as easier to gain access. Documentation is important, and this forum is one way I've done it.
1. Start with a complete running TJ that is not junk. Stick with a six-cylinder, or be prepared to buy any one of the respective transmission/transfercases/bellhousings of a 4.0 wrangler should you have a 4-banger.
2. Buy a COMPLETE SALVAGE DONOR VW TDI. My conversions have dealt with using a 2004-2005 BEW or 2005.5-2007 BRM. Similar rules apply if you want to use an earlier MKIV with the ALH engine. When you buy the whole car, keep it until you are done; there's a ton of valuable wiring and peripherals that will save you $$$$ and headaches. If you don't want to deal with commercial breakers, cruise insurance auctions for a total loss. Of course, make sure it's not a total loss for you, keeping in mind that frontal collisions can destroy the cooling system, hole the oil pan, but leave the rest of the powertrain workable. BOLO Sandy and Katrina flood loss cars - avoid water damage units.
3. Buy the Bentley workshop manuals and a scrip to Mitchell Pro-Demand.
4. Have competent hot work skills or a friend that does.
5. Have a place to work indoors; be prepared to scatter a two-car garage for 3-5 months.
6. Use Delphi WEATHERPACK connectors. Kits are affordable, the crimping tool is not however. But you'll never go back to crappy connectors ever again.
7. Be at least a production-grade mechanic that has a thorough understanding of Ohms Law, automobile electricity and electronic controls; CAN backbones, communications, diagnostics, and repair. OWN a J2534 Pass-Thru and a good laptop. Understand VW diagnostic routines, methods, and wiring breakouts (Current-TRAC). If you have A8 and/or T8 with L1, your ok.
8. Understand the differences, mainly from a network/engine management perspective, of the 97-06 TJ. This includes all three gas engines used throughout the production run. None of these vehicles used CAN, although the earlier runs used Chrysler Collision Detection, which was an early twisted-pair network originally developed for the 1988 Grand Caravan 4-speed "Ultradrive" automatic.
9. Eat, Pray, Repeat.

The 94 pin harness has 6 connectors that pass-through a weatherproof fixture in the firewall of the donor car. Unplug here and you'll get what you need. The colors breakout to:
Brown: various powered circuits, main PCM power
Blue: drive by wire throttle
Black: BOO, cruise
Orange: ISO 9141 k line
White: Controller Area Network bus
Grey: powered circuits, paralleled

|1979WagoneerLTD||With the powertrain wiring completed, the MK ll cranks and runs for the first time.|
|10-23-2013 09:33 PM|
|1979WagoneerLTD||Moving into merging the two different wiring systems into one integrated loom. This is the most labor intensive and time consuming part, but you can see why I put so much emphasis into packaging the hardware items first: wiring is alot more flexible than compressors, alternators, hoses, and intercoolers.|
|10-20-2013 03:08 PM|
|1979WagoneerLTD||Weatherpack and the other side.|
|10-20-2013 03:06 PM|
|1979WagoneerLTD||Mounting hardware is the same for this Jeep as the previous. Use the existing mechanical pedal pivot bracket as a template for the doubler plate that fits the VW drive by wire throttle assembly.|
|10-20-2013 02:45 PM|
|1979WagoneerLTD||This is the variable geometry turbo and intake runner solenoid assembly , as well as the bracket and wiring. This is located on the firewall of the donor car, which will likely not be included in engine purchase unless you specifically tell them too. This goes for the 60 and 94 pin harnesses and the throttle-by-wire connector pigtail.|
|10-18-2013 04:57 PM|
|1979WagoneerLTD||Cool eh? No, not really. This is a great example of how corrosion can set in a wire, even though the area is 12" away from the nearest connector.|
|10-15-2013 07:57 PM|
|1979WagoneerLTD||The existing battery cables can be used without any modification. I used a longer bellhousing bolt and extra nut for the engine ground. Chassis ground is accomplished at the negative terminal with strap to the firewall.|

Near-factory grade service manuals for VW are available from Bentley Publishers. The wiring diagrams are what VW calls "current Trac" and are for diagnostic use. They are not what most techs user friendly, but they actually are when you understand how it works.
Wire colors are in deutsch. Another thing to remember is brown is ground in VW electrics.
