i have a 1992 honda prelude with a swapped engine and i need to redo the wiring harnes is it easy to put one in by myself or how should i go about doing this please help.
The Acura Harness COULD (switching some wires around) work but why use it? The proper wiring harness costs less than $10. Why waste your time and trouble (and possible damage to your head unit)? Buy the one that is designed for your vehicle.
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.
Honda Prelude Wiring Harness
Each car has its own wire harness created for it on a custom-made basis. The harness essentially connects two types of essential things between electronics and the car itself. If you can not find the correct replacement part and you are technically knowledgeable, you may be able to recreate one yourself or purchase one that can me made to fit your specific year and model of car. If not, a trusted mechanic can handle it plus you will be confident that the wiring portion of your vehicle is correct. If your engine is not wired correctly you may have continual problems that will drive up the costs of car ownership quickly.
