New stand alone wiring harness arrived today, together with a reconditioned ecu with the immobilizer decommissioned. Stoked!

Go get @Old Nick
I've been reading in a lot a different forums. The bug's set-up (even though the engine is the ALH) is different. Supposedly, I'm supposed to avoid it... lol. Thank you for the heads up!
 
There are certainly a lot of differences between the Beetle and the Jetta/Golf, but those are primarily body and electrical differences. If you already have a wiring harness and ECU for that year the engine itself will work just fine. A few of the accessories might be a little different, but nothing springs to mind apart from the turbo support bracket. Being a 2001 model the engine wiring will be a little different from the 2002-2003 models, for instance the glow plug harness runs 4 wires instead of 2 and the ECU coding is a little different to help with glow plug control and diagnostics. @2gbFlashDrive is doing an LJ73 TDI swap using a Beetle engine, I haven't come across anything yet that is markedly different than on my Golf engine.

I would hold out for an automatic version, they came with the 11mm injection pump instead of the 10mm version used on manual transmission cars, which means one less thing to upgrade in order to achieve your power goals. The auto transmissions tended to give out pretty easily in the diesels, shouldn't be too hard to find one with a blown transmission for cheap.

Thank you, brother.

I got some time to work on this today…
