Convert VS V6 Maf $51 to VT V6 $A5

Has anyone re-pinned a VS V6 maf style PCM to run a VT V6 PCM, I know there's not many if any benefits just for shits & giggles was going to try it seeing it should be fairly simple?

I just went over diagrams & seems easy to test, to go from VS to VT;

B3 goes to F14
B9 goes to F8
D2 goes to C5
E1 goes to C16
E5 goes to C13
E9 gets added to A4(splice in)
Now there's 3 I'm unsure what to do with & guessing they will need to go direct to VT BCM & may need it for converting?
E11 to A/con request signal
F5 to Malf Lamp
F7 to fuel usage output

So guessing if not using the VT BCM those functions won't work & also not sure how the starter/crank will be affected?

1 of those was arse about, but apart from that it didn't work for some reason?

Not sure if it wasn't getting spark or wasn't getting fuel but ran for 1 second & then died!

Seeing it is an L67 there was also a wire for fuel pump pwm but you could hear with just ignition on the fuel pump pulsing every 3 or so seconds so not sure if that's an indicator for anything!
