Carb to FI wire extras?

[pappy52]

I have removed the harnesses from both a '87 Carb EA82 manual, and a '92 FI auto. the '92 has an extra white, flat, 17 pin connector that the '87 doesn't have. Also the '87 has a black box thing on the kick panel, whereas the '92 has the same thing in blue. The wire colors are different between the two. The conversion manual doesn't seem to address these. What do I do with them? Anyone willing to have me bring the harnesses to them to scope them out? I am on Camano Island in Washington.

 

Thanks, Jon
