Ok there is tons and tons of info and pics and charts on what you need, and how to drop the gsr/ b16/ b18 into the crx/ ef. But what I dont under stand is there is little wiring help with this. I found pics on the the ecu im using. Not exactly sure if the 88 and 89 have the same wire codes. But I found the 88. And I have 2 complete wiring harness's. The original ef and the ls/v wiring harness. But there is so many more sensors. Not exactly sure on how to run this. Well any help be helpful. Thanks in advance.
