Hondata OBD1 Pin wiring

Post by mjalaly » Tue Oct 28, 2014 1:58 pm

So I am making a custom harness for a b16 engine and had a few questions.

1) Will i run to any issues not wiring the following pins shown in red?
2) Is pin D1 just 12v+ from anywhere?
3) where does the attached wire from the jumper (yel/blk) go too?
4) where does the attached wire from the dist plug go to?
5) do a21and a22 come from the rpm/tach wire from the distributer plug? (Blue wire i think)
6) can a23 and a24 be jumpered once coming from the sensors and ground?
7) Why does the computer need the brake light switch input? D2?

any help would be awesome! I cant really tell from the wiring diagrams.
