Ok heres the deal I've got a full swap--from axles, to the ECU, altenator, dizzy (obd1 b18b) with everything except the harness. Its going into my 96 civic EX.

This is what I know I need:
obd1 - obd2 jumper harness
99-00 si tranny and drivers side motor mount

Now what the hell else do I need....I've gotten so many different opinions and people telling me different things, I'm sick of it. Just some guidance would be appreciated, thanks.

I assume that your going from the OBD2 to OBD1. So yes you will need a jumper if you plan to use an OBD1 ecu. Also you are going to use your stock engine harness. This is the only one you can use. Extend a few things, use your EX injectors, change the IAT plug, wire the dist plugs using the plugs off of your ex dist and a few other things. You need the rear tranny mount from the 99 si and the side cast iron bracket that bolts to the side of the block on the drivers side from the 99 si also. You need to use b series front lower tranny mount and the lower front block a/c mount. Any other specific question Pm me.

Year/make/model of car? P75 OBD1 or OBD2 ECU? The distributor for OBD1 and 2 are the same except plug styles.
