IMC AudioPioneer Wire Harness For 2010 And Up Deh-p8400bh Deh-p9400bh Deh-80prs Deh-4400hd Deh-1300mp Deh-2400ub

will it fit on a DEH - X2600UI?

Will this fits Pioneer AVH-1450DVD?

Will fit avh-4000nex?

I have an older pioneer deh-535 but the harness is missing one wire/pin. Are pins on the harness the same? if so I'll remove one from this harness.
