Connector A
Pin 23 PGI power ground
Pin 25 IGP2 Power source
Pin 26 LGI logic ground
Connector B
Pin 1 IGP1 Power ground
Pin 2 LG2 Logic ground

Re: wiring details
you shouldnt have to wire anything up except for the sensor wires that go to the engine bay (vtec, o2, etc..) unless of course your car is a dpfi chasss. in which case the jumper wont work unless you first set up your car for mpfi

Re: wiring details
are you going to be running vtec with this harness?
because the extra wires that you have to run yourself are for the 02 sensor and for the vtec connectors

Re: wiring details
Yes on the vtec and I will be running the wires for the vtec solenoid, vtec pressure switch, knock sensor, map sensor, and O2. Will post pictures later of the differences between the 2 conversion harnesses.
