Like the topic states, the car has all the mpfi wireing done all I need now is to wire up the obd1 dizzy. Any info would be helpful, Thanks in advanced...

 

You can make a obd0 to obd1 distributor harness or you can solder obd1 plugs to the obd0 harness.

You could do this but you would be wasting your time becuase the obd1 distributor doesn't work with the obd0 system.

 

I have a crx dx also and i tried to do the same thing but the OBD 1 distributor has 1 extra wire and it wont work with it. I believe that obd0 is a 5 wire and obd 1 is 6 wire. I just bought a distruibutor off of Ebay for $45.

 

Just buy a obd0-obd1 conversion harness from "blown90hatch" or "Droppedcrxsi" to work with the obd1 distributor..

Or buy an obd0 distributor and keep it simple..

Does this not also require the p28 ecu?

If you want to convert to obd1 you have to use a obd1 dizzy,obd1 ecu,and change the wiring to match obd1 ..You may or may not need a p28..Depends on your motor set-up..

My opinion is if you have an obd1 sohc vtec set up then get a p28
And if you have an obd1 dohc vtec set up then get a p72

 

My setup will be a jdm obd1 gsr motor I already have the obd0-obd1 ecu adapter, dizzy, and injectors. All I need to know is were each wire on my Dx distributor plug goes on the obd1 dizzy plug....
My wires are:

c1 from ecu
c2 from ecu
org/blu
wht/blu
fat white
orange
tan
The other plug self explanatory

 

Bump......

Do you have access to a volt meter/test light? I have a diagram i made up a few weeks ago i will post up later tonight if i remember.

So all I Have to do is match up the colors, And put c1 to blu/grn, c2 to blu/yel and the fat white wire to grn/yel........someone let me know if this is correct.

 

Just trace from the ecu plugs to figure out which wires need to be coming out where. Very easy to do with a test light or voltmeter.
