obd0 B16 wiring in crx
 

Looking for the exact wiring corrections to be made when swaping an obd0 b16a into (specifically) 1990 crx si. Somebody else did the swap and I want to redo all the wiring since it looks like ass and the altenator is not charging. I'm specifically interested in any wiring modifications needed to make the altenator work if any and yes I've checked all the usuall stuff. The si harness was apparently used. I've done a million obd1 swaps just not obd0.
