B20b harness issues

[Johns b20 sedan]

Alright so we have a little issue, I'm running a high compression b20b in a 97 civic sedan. Problem I'm having is one the harness won't work due to certain sensors not on the harness (auto harness) so pretty much I need a harness for obd2a that has a knock sensor plug, power steering plug (prefered), and all of the intake sensor plugs that this one doesn't have...not sure what all they are. What harness do I need to run fellas.....??? If anyone has a high comp. B20b setup in a 96-98 civic please post what you're running I'm at a stand still

I helped a buddy 2-3 years ago and just helped another buddy that is currently doing a swap this weekend regarding wiring and sensors. You'll need OBD2A 96-98 EX harness from a MANUAL Transmission car. If you are lucky, a 97-99 OBD2A CR-V MANUAL engine harness is 99% plug and play (secondary o2 wiring will need to added as it's on the body side of the vehicle).

You'll need to change and extend a few pig tails to match the sensors from the motor. If I recall, IAT, CFK, and most likely wire in the secondary o2 sensors directly to the ECU. Probably a few others I forgot.

So if I run a 97 ex manual harness what all do I have to do to make it work and what intake should I run, plus my ecu is p75-c01 obd1 with jumper so I shouldn't have to run 2nd 02 correct?

97 EX Manual Engine harness will be semi plug and play. A few pigtails and wires will be required to be changed and extended. If you state has emission, it is probably best to do the secondary o2 now then later.

So if that's the case what and how needs to be added and what needs to be extended?

Your're going to need to search it up or read what I posted on my first reply. Best yet, route the harness on the motor and you'll know exactly which pigtails and wires to extend. As I said, its been 2-3 years since I've done a OBD2A swap.
