Any issues swapping MAFs?

[fjcalgary]

I have a UCF20 1UZ second gen JDM engine that came without a MAF. I grabbed one from a pick and pull off of a Canadian market LS400 (pretty sure it was second gen, but didn't look too closely) anyway the plugs are different and they have since crushed the LS400.
My engine likely came from a Celsior, think there will be an issue if I find a plug to fit the MAF and swap pins?

Celsior and ls400 non vvti gen 2 run the same afm. Vvti ucf20 run the same as each other but different to early and different pinout. Ucf30 again different. Some of these can be interchanged with corrected pinout. Early gen 1 run alloy body, gen 2 onwards run plastic body. Alloy to plastic cant be done.

Thanks Kelvin! I should have watched that before I bout my gen 1 alloy bodied MAF. I'll have to find a proper gen 2 to pair up with my ecu.
