i have a 96 prelude which is OBDII and i bought a jdm h22 which is OBDI. i need to convert it to OBDII and i hear 2 different ways.

1. buy a OBDIIa to OBDI conversion harness and your done (hope this is it)

2. on obd2 there are 2 sensors on the bottom of the timing pulleys...they are TDC and CPS sensors. Your car will NOT crank without them and the only way to mount them and get them to work is an ODB2 oil pump, OBD2 bottom timing gears because they are notched so that the TDC and CPS sensors can read off of the gear. OBD1 bottom timing gears do not have these notices. basically changing the whole side of the motor(pulleys, ect)!! (please dont be it)

my motor will be here next week so i need to know asap, thanks!
