As for type II conversion you'll need BWD CBE103 that's the module from the late 80's buick, Olds etc. the newer module CBE47 that one seems to have an extra pin in the connector and as far as I know it is still in use, the extra pin is for what looks to me to be a second circuit in the crank sensor like a back up I guess I think you could use it by just leaving off the second wire or hooking the 2 together, this is just a guess at this point as I haven't tried it yet, but I intend to. The coils are easy to get E51 is the BWD part # as far as connection goes I bought the pins and a pin tool at NAPA the pins are .79 each and the tool is 9 bucks you can use a paper clip flattened a bit but its a pain in the butt. You can use the prefabbed harness from Caspers or whereever but they seem kinda price for me 60 or 80 bucks for about 20 buck worth or parts. Not for me! As far as the adapter plate goes I have an Idea on that I haven't got to play with yet, I'm going to use a late 80s bracket the one from the front right side of the FWD engine 3.1 or 3.3 I forget, and adapt it to fit the 84/85 plate should be real easy and cheap, think I'll give it a go Sunday after work. I'll take pics even though I have no Idea how to post them. I gave the BWD part #s as ref only if you go to the auto parts they can easily convert them to whatever brand you like (Delco), just makes it easier for you not having to explain what your trying to do and getting a blank stare from the 12 year old behind the parts counter. The pin outs for the conversion are in the tech area along with tons of other great info.
