Alright, just got everything swapped in, attempting to bleed the steering, not sure if I'm getting it though. The brake pedal isn't getting any stiffer though. I thought since the brake and steering hydraulics are now tied together that bleeding the steering would bleed the brakes too. Am I wrong? Do I need to bleed the brakes seperately?

Yep, 08 VMax. I haven't bothered with the SERVICE BRAKES SOON message yet though, no. I also have an extra electrical connector that was plugged into the booster, and an unused plug recepticle on the right side of the pump. Anyone know what these are?

Can anyone confirm if you can reuse the original master cylinder like you could on the nbs trucks? I am thinking you can avoid the extra headache of the different size fittings on the brake lines by just swapping over the master cylinder.
Also, no one has had any luck with the 'service brakes soon' message?

Idk if you can find a booster that has the same "spread" for the master. I have not had different boosters in hand to compare to my oem master.
I have not figured it out yet, but i do know that no matter how you jump the harness it does not clear the code like the old swap. You do have an ABS plug, that all you have to do is wire together to keep it from throwing the ABS lights.
I am planning to compare ohms on am oem setup asap

Did you jump the wires on the abs sensor like iamkeniff said?
Thanks for the help guys. I am trying to figure out all of this crap before I start ordering stuff to do the swap.
