b20b help: wiring harness and mounts!
im putting a b20b non vtec in to my 93 civic hatch.
i got a wiring harness(from a russian) and its obd2...for the most part, but alot of the plugs are on wrong sides of the motor, and there is no way of swaping the harness around with out putting more plugs out of place, and on the wrong side of the motor?...any one know how to solve this problem or tell me what harness i need and from what car, i already kmow it has to be an obd2???
then second: the mount that bolts to the engine itself puts the motor at a slant. i have yet to put the t bracket on but even when i do my motor will still be at the same slant?.....i think i fixed the mount.
so to any one who knows about a b20b swaps into 92-95 civic hatch i could use the help?

Basically you either use your stock Civic harness, or get an OBD2 Integra RS/GS/LS harness. With the Civic harness, either modify it to use OBD2 parts (distributor, alternator, and injectors), or use the stock Civic parts combined with the OBD2 parts (stock Civic injectors, stock Civic distributor or swap the Civic distributor guts into the OBD2 housing, and swap the voltage regulators in the alternators and use the OBD2 one with an OBD1 plug). Then there's also the ECU that you're using. If you're using an OBD2 ECU, you need the correct conversion harness to plug it in. You'll need to know whether it's an OBD2A or OBD2B ECU, and then get the OBD1 to OBD2A or OBD1 to OBD2B conversion harness. That or get an OBD1 ECU, and get it chipped with the B20B basemap.
The B20b swap is basically the same as the B18B swap. B-series driver's side mount, and B-series rear mount bracket. Though I'm not sure if the B20B mount and bracket will work, you may need one from an '94-'01 Integra.

Re: b20b help: wiring harness and mounts!
