i was about to follow the one on the link ^^^ but when i checked out my distributor plug i got two plugs in it??? anyone did this before? like which wires go to which plug (OBDO) from my OBD1 distributor?

BTW my car is a 1990 civic wagon 2wd and i found the link on the CRX/CIVIC FAQ

thanks! pls help

You need to run the obd1 distributor with obd1. OBD0 dizzy will not work with obd1 electronics. Refer to this thread for more info:

I recommend using the service manuals for all parts you are trying to run. They will answer any questions you have about part compatibility. Good luck G.

Are you running an OBD0 motor or OBD1? Because if you look at the plugs for 1 and 0, they are not even the same.

im gonna run an obd1 B18c1 with a obd1 distributor but im gonna use my stock harness (converted to mpfi) and plugs for it but the dizzy plug on my stock harness got two plugs thats in the pix but the plug on my obd1 dizzy only got one? same as the link on my first post

all i wanna do is to take the plugs out of my OBDO dizzy and put it on my OBD1 dizzy but on the link above that i searched the OBDO plug got only one plug unlike mine that got two plugs

Plus the conversion harness

There should be two plugs on the dizzy. One with two wires and the other with like 6 or 7 wires.

he has a dx so he still needs a mpfi plug or use the obd1 plug(2 more wires)

You don't need a jumper/conversion harness for the dizzy-side connectors. You can simply de-pin the connectors and put them into the ones you want. They all work and fit. Instead of some ugly jumper I just put the OBD1 connectors directly to my old engine harness for use with my OBD1 system (ECU, motor, distributor)

Ditto, splicing wires is harder to make clean than doing it "Honda-Like".

You need to do a dpfi to mpfi wiring as well

thats what i wanna do! do you have link on how to do it? like which wire from my OBD1 dizzy goes to which plug on my stock harness?

Damn I wish I took pics, I just did this like 2 weeks ago on my car..... not positive it works yet, but I followed instructions to a 'tee'

After you're done with MPFI you'll have 2 wires running directly to the ECU from your engine bay. Those 2, in addition to the 5 already going to your big dizzy plug, will make the 7 you need to run OBD-1.
I'll try and a pic of the sequence of which wire goes where, but it will be next week at the earliest.

Oh, and you need OBD1 engine harness plugs to work with your distributor plugs....so they fit, you know?

Most colors match up. There is one exception, you'll have two solid white wires. It DOES matter which goes where. If you look closely one is larger than the other (maybe not on the outside/insulation, but there should be a greater amount of copper inside one wire)

It's really just a match up game. To remove the pins from the connector you'll need a long, fairly stiff, metal tool like a eyeglasses screw driver etc. Here's a thread that kinda goes over what you need to know about depinning.

This depends on how you do the ECU plugs. If you use a pre-made adaptor harness, then itis vitally important to know whether they matched the distributer wires by the color or sensor. Because you will have to repin your distributer wires accordingly.

That's true but that would be a problem on the ECU side of the harness. So long as the ECU side of the harness is made properly then the distributor side will work out as I stated.
