1997 Civic cx 3 dr hatch with b20z from 1999 CRV
Does anyone happen to have the info on the 8 pin wiring connector for the dizzy on both a crv b20 and a civic? I have to get hold of a civic connector but in order to pt it on my b20 dizzy wires i need to know whats what on both sides in order to repin it. Any and all info appreciated.

 

Did you ever fix your problem?? Currently going through the same thing and im finding alot of threads with similar stories but no solutions. Just alot of suggestions. Anybody have this figured out?

 

This shouldn't be a big deal... you simply match the 6 sensor wires (3 pairs) color for color from the large OBD-2A style Civic plug to the smaller OBD-2B style CRV plug. Next, connect the large black/yellow wire from the large plug to the small black/yellow wire on the small plug. Lastly, connect the yellow/green ICM wire AND the blue tach wire together and join them to the yellow/green wire in the small plug. Done.

Incidentally, if you don't want to go through all of this wiring stuff, you can simply locate a '97-98 CRV or '96-99 Integra LS/RS/GS (1.8L non-vtec) distributor and it will plug straight up to your Civic engine harness. No wiring changes would be necessary.

 

I am currently swapping a b20z2 into a 99ek hatch and the b20 was previously swapped from a crv into a 96 ls integra so I either would have the correct integra dizzy or the correct crv dizzy but the distributor doesn’t plug into the civic harnes

 

You would need to use the '99 EK hatch engine harness, install it on the B20Z2, and use the '99-00 CRV distributor. You cannot use the '96 Integra engine harness.

 

I know that the teg harness is a 2 piece design I am already using the ek hatch harness I just must have the wrong dizzy somehow and also what should I be running for an ecu

 

The distributor from the B20Z has a single small 8-pin plug (with all 8 wire locations being used) much like the plug found on your '99 Civic engine harness. It is likely that since this engine was previously used in a '96 Integra, the distributor would match the single LARGE 10-pin plug (with only nine wires installed) found on the Integra engine harness. If this information tracks with what you are looking at on your end, simply find/order a distributor for a '99-01 CRV or a '00-01 Integra LS/RS/GS and it will plug right in.

As for the ECU... there is no stock version that will run the engine properly in your chassis. I would suggest an ECU conversion harness (OBD-2B -> OBD-1) and a tuneable engine management system and get the car tuned properly. The "next best" solution is an OBD-2B -> OBD-2A ECU conversion harness and an ECU (P74/75) from a '96-99 Integra LS/RS/GS.

 

I thought if needed to be 97 98 crv dizzy and also I have the 96 integra that motor was in so I cause just grab the ecu but would it work with the civic harness or would I need a jumper harness to go from the civic harness to the teg ecu

 

Your '99 Civic chassis is OBD-2B. You cannot use an OBD-2B ('00-01) Integra LS ECU because it has an immobilizer and your chassis does not... your car will never start with this ECU.

You will use the original '99 Civic engine harness from your car for this swap... which is OBD-2B. You can use the '96 Integra ECU, but you will need to purchase an ECU conversion harness (OBD-2B -> OBD-2A). The distributor plug on your original '99 Civic engine harness does NOT match the '96-99 Integra LS or '97-98 CRV distributor plug... you will need to get a '00-01 Integra LS or '99-00 CRV distributor and it will plug right up to your Civic engine harness. If you don't want to spend $$$ for another distributor, you may be able to find a distributor conversion harness on EBay (plugs an OBD-2A distributor into an OBD-2B engine harness) and then what you have works.

 

I think I’ll just get a dizzy from the wreckers thanks for all the help I really appreciate it

 

hey man so I bought a new dizzy and the OBD2a to OBD2b jumper for the p75 and everything else is done and the ecu is pledged in but the car just cranks and won’t start, and i don’t hear the fuel pump priming or the main relay click and I don’t think I’m getting spark either, wondering if the ecu could be bad or the jumper harness
