ok so im atempting my first swap this weekend, and i need a little help. i have and integra parts car obd2 and im buying a obd1 95 civic. i got all the mechanical stuff down but im still confused on how to wire the obd2 motor into the obd1 car?! can someone help in english please!? im not the brightest when it comes to wiring and instructions :p

 

You either need to get an obd1 dizzy or make a jumper to wire the dizzy, which I wouldn't recommend as (I believe the crank angle sensor) is on the crank on obd2 ls whereas its in the dizzy on obd1. I'm sure you can find a write up somewhere wiring that sensor in to make it work but save yourself the trouble. Swap out your injectors from the stock civic engine and use the harness off of the civic engine. Other than that its pretty straightforward. Bolt in and plug up. Also grab the throttle cable out of the teg while you're in there. You may have to extend a couple wires but its not that hard just keep up with what wires go to which sensors, I have seen some mixed wires fry an ecu. Also grab an obd1 p75.

 

google. OBD2 engine into OBD1 civic

 

If that were the case he is liable to get tons of engine downgrade writeups for everything from h to d to k to j and so on...

 

ive tried googling it its all confusing, so i use the engine harness of the d series and and the injector, wire the dizzy and im good?

 

The B/D series use the same injector, I'm not sure if the OBD1/OBD2 injectors are different like the OBD0/OBD1's (even though they are still saturated injectors on OBD1/2 vs Peak/Hold OBD0). Maybe someone else who knows for sure can elaborate on that subject. I'm not into OBD2, sorry. If the injectors are the same plug then you can use the ones supplied with then LS ans save yourself the work of changing them out, if they are different, save yourself the work of wiring and just change the injectors. I WOULD get my hands on an OBD1 distributor, as I mentioned above for the reasoning mentioned above. Buying a new dizzy vs the hassle of wiring in that crank sensor to your engine harness. Craigslist it, or hit up the junkyards or part store or a good buddy who has one. Once you have these issues resolved then from there all the other sensors should have the same style plugs and will work just fine. Just make sure you keep up with the IACV plug as a short on this wire WILL FRY AN ECU. So, pull your d series and LS, sit the engines side by side and note the positions of the sensors (they will be in similar albeit different places which is why you may have to extend your factory harness in a few spots). Remove the harness from the LS and then remove the harness from the d series (labeling plugs as you go doesn't hurt) and install it in a similar route as you removed it from the d series onto the LS. Plug up what you can but you may have to extend a couple plugs. If you plug up one sensor and can get no more then unplug that one and start doing others, leave any that pull or put unnecessary bind on the wire, extend those using solder/heatshrink tubing. Once the harness is installed you are ready to install. **While investigating the injector situation, inspect the connection to the fuel rail on both engines, you may need to use the line from the filter from the integra. PM me if you have anymore questions at all, as I'm here to help the community even on the simplest things, NOT to gawk and discuss swap pics.

 

just got some bad news, idk if they stock d series wiring harness is there, can i use the wiring harness off my ls and use the obd2 ecu? is there anything else the ecu runs?

 

No. I would find a harness for the engine then. The amount of wiring you've suggested doing you may as well swap in an amg v12.

 

Msd makes a dizzy jumper harness and its not too expensive

 

if i use the jumper harness, so i still need to wire in the crank sensor? i found it, and its only 40 bucks

 

Yes you will still need to wire in the crank sensor, and the jumper will only help if you have an obd1 engine harness to plug up to the car. Buibg the jumper won't make the harness currently on the ls work any better. Save yourself the headache and find a wrecked Teg and buy the harness off the engine. 94 or 95 only. While you're at it buy the distributor too. Even with the jumper you still will be missing a sensor which the car will run without, but the last one I seen that way ate coils every few days until the right dizzy was installed.
