q45 maf ground?? chassis or pin 26?

[meet07]

Ok I coped a q45 maf as well as a q45 tb about 2 years ago. I used the tb and not the maf. Well I finally maxed out the stock maf and decided i might as well use it..

I notcied that the q45 maf has:-signal-grnd-power

then the rb25 has:-power-12v ground-signal-signal ground

what is the ground on the q45 maf?? is it a chassis ground or is it the ground that goes to pin 26?

thanks

Chassis is fine if not better because you want a really short and clean ground.

so pin 26 aka: signal ground is ok left alone then. I have a SAFC to change the hotwire settings.
