3 plugs means its a carbed model, The RFI has 4 plugs.
There are two different mpem's that I know of that take 3 plugs like that. Either the pre 99 version that doesn't have a throttle position sensor and the 99+ that does have it. Both look the same though. Same plugs in the same place.
While your waiting, Assume there was something wrong that caused the PO to have thrown out the old mpem.
Its worthwile to check the wiring and perform some end to end continuity checks on the harness. There could be something that will cause there next one to blow.
Thanks for the shout out...yes the 97.5 and 98 are special, a 99 and up will NOT work.
I ship to Australia all the time that is no issue.
Do not buy from that guy on ebay...hes got less than ideal integrity. I would be a bit more but yes would also include a programmed key, tested and ready to rock.
