I've prepared my notes and schematics from working notes, etc., to "as built" plans. I have some things in Excel and some in WordPerfect. Of course, I've never actually prepared a complete schematic as fas connecting the dots. The labeling is such (connectors identified, color, etc.) that it is fairly straight forward and easy to follow.

If everything goes well (time is the issue), I plan to print everything out and place in a ring binder for the trip to the Fest.

In reference to recent comments in various posts, I did notice several instances where color code did not match what was in the Bentley......... brown tape and pen to identify what I did until the end!

I've read thru this Thread again (number of times), unless I missed it, no one answered the qustion(s) about the Load Reduction Relay.

As far as I know, all vehicles have that Relay or one that serves the purpose. In the start mode of the ignition switch, the Load Reduction Relay is deactivated cutting off current to practically everything but the Starter and components necessary to start the engine. (Like, head lights, marker lights, brake lights, power outlets, defroster circuit, AC, etc., are without power during engine cranking.)

I don't know the answer, but I didn't do anything with the load reduction relay in my car and it works fine. That said, I have a new 90ah battery, heavy cables, and it is hot here.

I think you are correct Andy. I'm not running that, just left it disconnected and everything operates the same as it did when I was running MSA15

Yeah, the Load Reduction Relay in the vehicle that you are setting the TDI engine performs that function (load reduction). The LRR from the donor vehicle is not necessary at all!

If you notice, the "hot wires" involved with the LRR are Black & Yellow ....... that's typical of those circuits!

I have found that a load reduction relay is not necessary in my situation. My vehicle has very limited electronics, and the engine still cranks fine with cooling fans and lighting. I could imagine a car loaded with amp drawing electronics making the starter hard to crank without one.
My swap has about 40 miles(and climbing) on it now thanks in part to this thread.

Okay....The OP is in the house!!!

My TDI swap is running and I'm so damn glad I built this guide because it was incredibly helpful. There are a few changes and I will be posting them soon but for the most part...it's highly accurate and will get you up and running...

i realize that this is an older thread, I have read it a number of times and wondered if this was ever "Stickied" I always have a hard time finding it and thus it is now in my Favorites.

On a side note is there any noticeable differences between an alh wiring schematic and a PD bhw (from a Passat).

I cannot find the thread that talks about these differences.

Thanks again for all the info.

ALH and BHW will be very different. They are different engines, AND different chassis.
