Swapping OBD2a into OBD0 Civic
I'm wiring up an OBD2a B16A2 into a 91 Civic hatch. I've had limited luck finding wiring diagrams of how the electrical systems are in both the 98 Civic that donated the engine and the 91 Civic that previously had a 1.5 in it.
I'm looking for some diagrams, I specifically need info about all the wires that go to the green connector close to the ECU. I've found plenty of ECU pin outs but almost no information about anything else. I need to find out where the tach is connected, both in the OBD2a loom and inside the car.

me and my buddy just finished swapping a b18 into his 92 hatch which was a 1.5 and the engine was a obd1 and the b series is a obd2 and his car runs like ----!!! we did splicing and custom ---- to the harness and still no luck!
we put my ecu in his car and it ran much better. he is still using my ecu but he went out today to get a new ecu because mine is a chipped p28 and i need it back cus im getting my turbo eg tuned next month
