bad iac pig tail
 

Does anyone know a part number for a pig tail that would fit merc iac valve for part # 862998 . 496 ho burnt iac and pig tail 3 rd time.lost 2 ecm 's before . Had whipple repair them. Also just a thought for others having same problem my sun pad ends right around iac location thinging water might be dripping on them. Thanks for input

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.
