MAF Plug configuration for the 2nd Gen GS400:

4: +B - Black/Red(wire)

So all you do is basically match the signals from the 430 to the 400 and vice versa; that is e.g. THA to THA: Pink/Blue from the 430 wiring to White/Red on the 400 plug. It is very simple, the hardest thiing is actually getting the MAF sensors with plugs from both cars to do an even swap. The only thing is that you will have to use only applicable 400/430 intake systems for whichever car you have them on. I hope that makes some sort of sense. If anyone wants to try this and is confused, hit me up and I will try and explain better...

As per Brian, I will try to get some pics up soon to show what I did.
