Alright so my dilemma is as follows, I bought a obd 0 (not sure) b18a1 motor and put a obd1 ls manifold and obd 1 dizzy, my question is what else do I need to swap on Motor to be able to run obd 1 ls harness I have? All going into 95 Honda civic ex.

 

Anyone?

 

Alternator and injectors

 

obd0 and obd1 alternator plug should be the same.
did the ls manifold you swapped come with injectors? if not, i think you can run the civic ones. you've got the distributor already. you will also need to run the 2 wires to the fan switch. it's on the back of the block on the a1, while your civic switch is on the thermostat housing.
you'll probably need to chip your ecm, or run a p75 ecm.

 

You'll also need to run your cars 4 wire 02 as well if your A1 was the obd0 1 wire style. A1s can be obd0 or obd1.

 

I have a obd 1 ls harness can't I just plug o2 into that harness?
And fan switch won't my obd 1 ls harness plug into the fan on my harness? Or are you talking about something different?

 

Obd1 o2 has a four wire o2 and obd0 has 1 wire.
I'd get a obd0-obd1 jumper harness, wire in the sensor and use the obd1 ecu.

 

My car is obd 1? I'm so confused!

 

His car is a 95 so it's already obd1. For fan switch the obd0 location is here:


Obd1 is here:


You'll have to extend the wiring to the back of the block.

 

as you can see also, the connector is different. use a pair of bullet type connectors for the obd0 switch
