I have a 93 honda prelude that has a h23 A 1 non VTech motor. Will the wiring harness from my h23 fit and work on a h22 VTech obd1 motor
I'd recommend that you try and find a U pick/pull auto wreckers and hopefully they will have some vehicles like yours so you can not only find a good replacement harness but also learn more about what exactly is involved.Basically any harness has male-female plug in connectors that may run from under the hood to different comps and sensors etc and it could run to the inside of the vehicle to a fuse box or fuse box connector.Some harness's run along the engine and plug into different devices such as the fuel injectors etc then runs to some firewall etc plug in connectors.Many of different ground wires that may run to the frame/chassis or battery. Hope that helps and best of luck.By the way don't forget to clean the ground surfaces and the wire o-ring connectors with a wire brush and sandpaper etc before you install the replacement harness.
No, I have done this swap and the ECMs are different. You will need to replace the harness as well as the ECM in order for your car to even run correctly.
