Yeh, do a search for 496 iac's and you'll find aftermarket pigtail part #'s.we have looked it up/posted it many times.

melted connectors comes from the very High duty cycles of the IAC. this overheats the IAC and in return burns and or melts the connector and that in return has the possibility knocking out the IAC circuit within the PCM 555 / ECM 555. Common problem I see all the time and see it internally of the ECM / PCM when I open them up to see if I can repair

I bought a iac survival kit from marinedesigncorp which will take out a fuse and protect the computer if the iac does fail.
