First Off I Am Putting A B16a Obd 0 In A 89 Civic Hb Which Is An Si
Now Wat Axels Can I Use For This Cause I Tried Integra 90 Ls From Discount And They Didnt Fit So Wat Axels Now Also The Wiring Harness That Came With The Motor Doesnt Plug In So I Took The Si Harness And Try To Fit It , The Injectors Didnt Fit And It Did Not Have Vtec Wire For Stock Harness Also And The Rights If You Were Looking At It In Front Of You The Wires Would Not Connect The Plugs Are Grey One You Have To Connect And The Other You Dont Have To So My Friend Mike Which Comes Around Every Now And Then Said I Need An B16a Obd O Harness So It Could Fit A 89 Si Hb He Said It Is And Obd O B16a
The Wiring From The Engine Bay Dont Fit On Either Of The Sides Of The Harness So Somebody Help

ALSO IS A CRX SI WIRING HARNESS THE SAME AS A HF CRX WIRING HARNESS

AND HOW DO YOU TELL THAT THE B16A1 I GOT IS AN OBD 0 IT IS STAMPED ON THE BLOCK B16A THAT IS IT

 

I think most people use their stock harness and modify it to fit the engine connections.
The SI harness is different than the HF(I believe HF has throttle body injection while Si has port)
The serial # will tell you what year its from. I think the "1 million" series are obd0.
