Apexi PFC questions

[Driver11324]

I picked up a PFC for a good price but its for a blacktop rather than a redtop which I have. Everyone is telling me that I have to repin the redtop ecu plug in order for it to work, Others say the two ecus are interchangeable, so are the PFC's. Which wires have to be repined? I have searched EVERYWHERE and all I come up with is a pinout picture that gives me no information. I have gone through a bunch of FS threads for the PFC's and 2/3 times the people say it can be repined and there are only 4 wires.

Your lacking information

If the PFC is for #62 ECU and you have J4 then you need repin

I made a thread about this once

do a search for "62 to j4 ECU" in google and it will come up first link
