Where are the 8 wire plugs on the OBD1 harness?
The yel/blk wire from each of the injector plugs leads back to the 8 wire plug mentioned in #1. The OBD0 injector plugs must be cut off and the OBD1 injector plugs soldered on. Match the injector colors to each other, as they are the same on both the OBD0 and OBD1 harness.
Is the engine harness from a 92 Civic DX auto?
Partial engine harness from the 93 D16Z6 and harness parts from a 92 Civic DX auto 4. 95 Civic EX P28 ECU (manual) 5. 92 Civic Si distributor
What are the pinouts for the obd0 ECU?
1. Injector 1 Brown 2. Main Relay Ground Black 1 3. Injector 2 Red Red 4. Main Relay Ground Black 2 5. Injector 3 Light Blue 6. Purge Cut Off Solenoid Valve Green
Where is the O2 sensor on the obd0 harness?
A 4-wire O2 sensor must be added. In order to do this, 3 lines must be added to the harness. One line runs from the O2 sensor plug to the 8 wire plug mentioned in #1, this wire is yel/blk. The second line is a grn/wht line that runs from the O2 sensor plug to any location on the grn/wht wire on the OBD0 harness.
Where are the GRN / WHT lines on the obd0 harness?
One line runs from the O2 sensor plug to the 8 wire plug mentioned in #1, this wire is yel/blk. The second line is a grn/wht line that runs from the O2 sensor plug to any location on the grn/wht wire on the OBD0 harness. The third line is an org/blk line that leads to the ECU.
What kind of plugs do I need for an OBD1?
There are two methods of doing this step. Note: Using a 92 Civic ECU (OBD1) plugs is best for this conversion due to it having all the necessary wires for the Z6 ECU. If 92 ECU plugs cannot be found, try to get the plugs from a Si or EX, otherwise additional wires will need to be added.
Is there an OBD1 to RDX charge harness?

A 4-wire O2 sensor must be added. In order to do this, 3 lines must be added to the harness. One line runs from the O2 sensor plug to the 8 wire plug mentioned in #1, this wire is yel/blk. The second line is a grn/wht line that runs from the O2 sensor plug to any location on the grn/wht wire on the OBD0 harness.
Is the injection resistor compatible with the OBD1 ECU?
The injection resistor must be removed from the circuit. This is because the OBD0 injectors are not compatible with the OBD1 ECU. In order to do this, the yel/blk wire from the green plug on the injection resistor must be pulled. It will be relocated into an open space in a gray 8 wire plug from the OBD1 harness.
