OBD2B TO OBD2A PINOUT HELP
Hello,
Im currently researching on how to repin my obd2b (2000civic ex) car to put in an obd2a ecu, reason being i purchased a obd2a itr swap and i dont feel like paying crazy amounts on a jumper harness. So i have eveything set except on the C &D connectors for the obd2a,
c23 IP+ HO2S
C24 IP- HO2S COMMON
C25 VS + CELL VOLTAGE
D13 SHO2 SENSOR GROUND
So those i dont have anything going to them from my obd2b harness. I read somewhere that it said those are for 5 wire o2 sensor and not used with 1 wire o2. Does the 5 wire reference a 5 wire o2 from the obd2a (96-98)? I dont believe on the 99-00 civic they have a 5 wire sensor so do these just get left open?

Crazy amounts? At the most you'd pay $200 for a chipped OBD1 ECU and jumper harness. Your P73 probably cost at least half that.
Anyway, the 5-wire O2 doesn't apply to your engine or chassis so you shouldn't even have wires for those.
SHO2 means Secondary sensor, post-cat. That D13 signal ground can be tied to C7 or C18, it's the same node.
