I have an 87 maf tpi setup. I want to convert to speed density. I plan on probably just buying a gm speed density harness. My problem with this is that I need to know what all is different about the chassis harness and if I can just change it to work or if I need one from a tbi car. I know that my spedometer wiring will be different. I have been told that you just dont use the buffer. I would like more information on how to get rid of it. Also I think that I may have read that the aldl connector would be wired different. If any of you know what I need to do to fix any of these problems or know of any other that I will have to deal with pleas help me out.
Thanks

Ben

Nuff said.

P.S. You don't need the whole harness to convert to speed density, just need to repin some of the connections and change a few sensors. My first question would be why do you want to convert to speed density?
