M50b20 nv 6 pin maf conversion help :(
hey guys, im in the middle of swapping out my tiny 2.75 6 pin maf in my 520 for a 3.5 4 pin maf from a 540,
I started with wiring up the wires the same way as the 540 but obviously having the 6 pin (which only has 5 pins being used) I have a left over wire,
I have 12 v power and the main ground hooked up but now im left with three wires on the dme side and 2 on the maf side....
is this combination not compatible at all or do I need to do some wire running to the dme?
