Then get the heat sink and socket from the OBD1 alt and put it in the new OBD2 alt, all screws will line up. Now get your OBD2 alt for the B-series engine and do the same as above, Then you need to remove 4 screws which hold the heat sink and the round conector to the alt, once all the 4 screws have been removed slide the heat sink and plug. I used my old OBD1 alt for my D15B engine,įirst you need to remove the 8mm nuts on the back of the alt I can say i was not able to find anything on the net, but there is an easier way to do this.

It is also a good idea to wrap the new wires in loom much like the stock harness parts are.įirst of all i know this thread is old, but i kept coming across it when looking for info on how to rewire a OBD2 alternator to OBD1 when doing my B-series swap.

it retains the stock look, and makes your swap look much more professional than simply duct taping wiring together. This way, you can simply plug in your obd1 GSR or del Sol VTEC motor with its harness right into your car.
Re-pinning tools are fairly inexpensive and can be found at most electronics stores. The professional way to do this is to actually re-pin the harness connector on the passenger side shock tower to accept these new wires and re-pin the ECU connector harness as well. For the rest of the model years, and the lower trims, you will need to run all of these wires. When doing a GSR swap, all that needs to be run is the knock sensor and the IAB's. Also, it has been our experience that most 1992 Civics, regardless of the trim level, are all wired for VTEC already. If you have an EX/Si/VX most of these are already ran. Secondary Intake Solenoid (IAB) Pink/Blue A17 Ensure that the following are all hooked up before you get any deeper into trying to figure out what's wrong. Most jdm motors will also follow this guide, but some changes will be made to your stock harness for it to work properly. Here's a quick chart of what to check when wiring in your 94-95 Integra B18C1 or 94-95 del Sol VTEC B16A3 into your EG. Since there were way more base models produced than EX/Si models, chances are that your car is not already wired for a VTEC swap. The most common cars for swaps are the EG-chassis line of Civics. Wiring an OBD1 VTEC B-series into a 92-95 Civic PLEASE just a straight answer from the OBD GOD! THIS is pretty much what I found everywhere from all of my research on the internet in 2 weeks. Only thing I see is If you did not buy an obd2 swap for your 6th gen, things get much more complicated, and we will attempt to tackel that sometime down the road. I am just trying to look into every viable option other than repinning my whole wiring harness.Īlso pissedoffsol, I have gone through the site numerious times and I can seem to find what your talking about. This was making me think why can't I do the same thing with my OBDI B18c engine harness and get a OBDII B18c cabin harness? If I'm right the OBDII Civic doesn't come apart on the shock tower but the Integra does, in that case run OBDII cabin harness to OBDI engine harness, get OBDII to 1 converter and plug in my ECU ? RIGHT? PLEASE CORRECT ME IF I'M WRONG. On honda-tech a couple of people were saying the plugged in there OBDII swaps into there factory OBDI cabin harness (the opposite way of which I want to go, I know) I'm not sure if there talking about where it comes apart by the passenger shock tower or in the car itself.
Its been a couple of days, but I have a few more shots in the dark for you guys. It involves to much extra work, for something I already have complete (injectors, distributer and on a B18c a oil pump sensor)
