I am in the middle of the same project except im welding in all the holes. I am keeping those 10 pins out but im going to try and hide them behind intake some how...because obviously they go to your injectors etc...etc
if one of those wire harness goes out into fender wall...Im pretty sure its for your cruise control. At least thats what im guessing your talking about.
anyone ever purchace one of those black pieces that screw under the upper intake...that hook up like three vac lines.
Where was it bought from besides ford
