IS-F Motor & Tranny Swap into ISx50! The real deal

HaHa, nope. I've done a few 2jzgte swaps in the past but nothing this electronically involved. Really, it just takes time and TIS.
I elected NOT to use the ISF cooling ecu setup. I wired the relays and fuses as they were on the ISx50 setup. Hoping I don't run into any more surprises once I get it running.
....Which is within the next few weeks. I'll be scheduling an appt. with Lexus to have my VIN seeded into the ISF engine ECM and then I'll be able to crank it over.This coming fall/winter I plan to tackle the Greddy S/C setup.

Goodness what a thread, lots of good information here, now as far as the swap, once you have completed the conversion would you consider a parts list and a wiring diagram for those gear head junkies out there that may consider the swap?

I have stuff scattered around in spreadsheets and notepad. I'll put it all together when I get some free time at work.
Two new things:
1. Anyone doing this will either need the ISF shifter OR they may get lucky like I did and use the cotterpined shifter to shift arm bracket from the ISF. (I don't believe this piece is sold separately from the shifter though). The IS350 bolt/stud was off by about 1/2". Pic below.
2. Never did I think the Tranny crossmember wouldn't bolt up to the furthest hole set on the ISx50 body. We have EIGHT (8) drilled/tapped holes and the IS-F tranny puts the last ones about 49mm further back. I drilled one of the spaces out but its just a thin walled aluminum pocket...couldn't tape threads.
I had my welder fab two additional pegs to the IS350 crossmember to allow it to bolt into the stock location. Its very rigid and there should be zero issues but I have him working on a custom piece for the near future just because it would bother me.
Piece needed to align IS350 shifter with tranny shifter-
All bolted up and torqued to spec-
I'll be putting more of the front end back together in the coming days...Just picked up my tranny cooler-
Gotta luv Summit Racing retail store clearance. Picked up some Mishimoto water hoses that I may or may not use.
The new tranny xmember will be similar to this---

Inching closer to finishing this thing up! Last bit of items I didn't account for needing modified early on in the swap:
ECMs are back in place after having to fab (plastic mold) mounting tabs on the ISF box to use ISx50 bolt holes.
The ISF uses a pressurized coolant reservoir whereas the ISx50 its built onto the head/water routing. I elected not to use the ISF reservoir due to size and fit so I went outside the box and have an STi coolant reservoir in place. I'm very happy with the fit and finish and it offers expandability in the future. (I plan to do an aftermarket radiator and slim fans once I boost the motor later on.)
The oil cooler previously pictured was a complete POS. I'm waiting on my Earl's cooler to arrive and then I'll finish up the lines and mounting. Air intake needs welded up but I think I settled on a final version so its just about complete. Other than that, I'm only left di$king around with Sikky's oil dipstick trying to get it lined up perfectly between the headers and frame rail....I think they sent me a bent one and its been a headache trying to figure it out.
Once that is complete I'll be filling fluids, strapping battery down, bolting exhaust up, cleaning things up and calling this done very very soon!
Caliper teaser! Finally got my Brembo GT back from powdercoating. Fronts are a massive 6pot on a 380 2 piece rotor. Rears are a big 4pot on 355 2 piece rotor.
