just put a d16a8 in my 89 crx si and it is throwing a code 20 which is a eld. I heard you can get a jdm fuse box and that will solve my problem but i cant seem to find one of those anywhere. Does anyone have any ideas. How the hell do i fix this problem

You can replace it with an eld from a usdm fuse panel or replace the whole fuse panel if needed.
