i have a 90 DX hatch that had been converted to MPFI and obd1 by the previous owner. They kept the jumper harness, but i bought a new one. my problem is that the distributor wires for CKP and CKM have been cut for some reason, and i dont know where they should be on the obd0 ecu plug. (enginge harness has been wired with obd1 dist plugs)

also, there is an extra wire added to either the TPS plug or the MAP plug that is just cut off? the car had nitrous and an after market tach. could it have been for either of those?
