obd0 --> obd1 harness, what extra wires are there to run from the obd1 ecu?

i've seen pics of this type of jumper harness and there are a few wires that have no where to plug into on the obd0 side, but obviously are important for the obd1 ecu to read from. what are these wires?

i ask because we'll be putting a b17a in my wife's 90 EF, and I think I want to conver it to OBD1 for the hell of it.

What are the advantages/disadvantages of obd0 vs obd1?

OBD-I is yummy.... I had it in my CRX with a D16Y8.
You basically have to run 2 more wires for the 02 sensor, 1 for the VTEC solenoid, and 1 for the VTEC pressure switch.
This should help.

IN that link, arent they using the obd0 ecu and just runnin extra wires to run the z6 in it? Thats not really converting the car to obd1, since your still using the obd0 ecu, dizzy, sensors, etc.
