is that thread for an obd1 B series distributor into a 00 civic ex?

CivicSpoon

damn, it's not. It's OBD2a.
This should be correct:
OBD2B=OBD1
YEL/GRN=YEL/GRN
BLU=BLU/GRN
GRN=ORN/BLU
YEL=ORN
BLK/YEL=BLK/YEL (On the obd1 2 wire plug)
WHT=BLU/YEL
RED=WHT/BLU
BLK=WHT

Ch3mik

so then let me make sure i got it right, the diagram you posted . you mean

OBD2B equaling the engine harness wires right? and obd1 equaling the dist plug wires right? thanks man

what about the blue wire that sits by itself on the drvr side near the firewall? you didnt list that one in the diagram

thats the rpm signal wire

That blue wire isn't connected to the OBD2b plug, so I didn't put it in the list. But it's the other wire on the 2-wire OBD1 plug. When that plug is hooked up, the Black/Yellow wire will be on the bottom and the Blue wire will be on top; like this

I ended up usin both the male and female ends of the obd2 plugs. ill get a pic of everything i have. car started up , just throwin a CEL and i need to find out how to get the codes to come up .

Ch3mik

car is throwing no more codes but still runnin like crap

I thought they are the same exact color codes, just two other wires goto the other plug.

also you could just order an adapter http://locashracing.com/store/...be64e
i just can't figure out where the conversion chart is located.

I have it hooked up like this and its misfiring, the timing is dead one, the valves were just adjusted, the plugs and wires are fine, weve tried 2 distributors . anyone have an idea of wat else it could be? im getting no CEL and all the threads i found on misfiring point to all the stuff ive checked already. :/

bump......any update?

Ch3mik

it ended up being the valves causin it to misfire. they were so far outta spec.

is the correct way. the blue wire gets connected to the single blue wire by itself on the drvr side close to the firewall. its a single wire with a plug on the end , with a rubber cover on it. its mounted on a small bracket. you cant miss it. I just depinned the wire and ran the blue dist wire up to that one underneath the manifold
