First off i tried search but cant find info on obd1 swaps only obd0 stuff.
I got a 89 crx si , i will be converting to obd1 with a jumper harness so i can run hondata , now i've gotten all my obd1 parts but im just wondering about the wiring , from using my stock crx harness will all the plugs just plug in to the b18b stuff ? ie. sensors and all that . Any help or info is greatly appreciated as i will be doing this swap within the next two weeks .

Yeah, some sensors you will have to splice connectors in (like ECT) but for the most part (besides converting it to OBD1) it is plug and play.

 

what's a ect ?

 

Engine Coolant Temp sensor. OBD0 uses on the block, OBD1/2 uses one on the thermostat housing.

 

haha that makes sense now , stupid early saturday mornings

 

I have a 96 B18B1 in my 91 CRX DX but I used OBD0 parts to keep it simple. It's a daily driver, not boosted or anything so I saw no need to go OBD1. Basically your stock engine harness will be completely plug and play on the B18B1 other than the coolant temp sensor as mentioned and then the OBD1 parts that you'll be using (distributor, injectors, 4 wire O2).

 

ok good too know thanks for the info .
As for me going obd1 its because i will be going turbo as well with hondata , so i gotta convert to obd1
