Onehundred80 check my thread under "spoiler up" - have tried everything except taking it to the dealer and by the sounds of it they are going to tell me I need a new BCM. I have checked and all part #'s end up as the new one 05189811AA so I am again assuming that they are interchangeable. Reading the 500+ threads on spoilers up and BCM's it seems that they have been replaced with out the dealers help and just require 30 seconds in the "on/accessory" position to "accept" the new BCM
Mr Miata -thanks for the lead -if it came out of an SRT hopefully it will make my n/a go faster..... For that price I am willing to give it a try!
