I have a 93 hb that im trying to put a jdm b16a1 into. The question that i have is what do i have to do to make the wiring harnes work with the usdm car. Hasport told me that i can use the sohc d16z6 harnes with some mods from the jspec dohc b16a1. However i need a little more help. If anyone has a wiring diagram for this or just tell me the wire colors for both harneses it would be every helpful so i can compete this swap.

 

this has been covered a million times.

all the info you need.
using the JDM RHD harness would be a PITA.use your old Z6 harness,extend the wires that need it,and add the wire you need.easy.
