bmsgaffer86: I am a little confused, are you attempting to add a 16 pin connector conversion to your 12 pin odb-I connector? do you have one of each type?
odb-II connector pinout info can be found here.
But i am not convinced that you need odb II
Here is where i stand with my research right now for my 93 bonneville
I am 99.9% sure that my car has the ecm 16141470 based on this page
and running across a post where someone referenced a '93 bonneville and that number for their ecm.
and also based on this link
i was able to find out that the program id byte is $5B4
also if you notice there is a blue circle with an i in it. more useful info
now my next step is to actually make the connector, which this link should provide what i need
so that will happen in the next 2 weeks hopefully.
then luckily myself and a group of friends are all programmer geeks, so we should be able to work up a pretty sweet software set based off of other info that we find on sites.
I will document the building of the aldl ODB I to serial connector to the T so that anyone can repeat the process.
If you think i am wrong with any of my info, please let me know
