For enthusiasts looking to enhance the reliability and performance of their 1990 Honda Prelude Si OBD2, upgrading to a Mil-Spec engine harness is a game-changer. Our OBD1 Mil-Spec Engine Harnesses are meticulously crafted in the U.S.A., utilizing Mil-Spec Teflon coated wire renowned for its exceptional 200°C heat resistance. This upgrade is not just about replacing old wires; it’s about investing in superior quality and durability for your classic Honda.
While visually similar to our standard wire-tuck engine harness line—distinguished mainly by the single black wire color and expandable loom—these Mil-Spec harnesses offer a significant step up in material quality and longevity. We understand that customization is key, especially when working with a specific model like the 1990 Honda Prelude Si OBD2. That’s why we provide a range of options to ensure a perfect fit for your vehicle and engine setup.
When selecting your harness, consider the following crucial options to tailor it precisely to your 1990 Honda Prelude Si OBD2:
Vehicle Type: Specify your chassis type. This selection is vital as it determines the correct interior “Chassis Adapter” needed for seamless integration within your Prelude’s cabin. Ensuring compatibility from the engine bay to the interior electronics is crucial for a hassle-free installation.
Injector Adapters: Our comprehensive Injector adapters dropdown menu caters to various injector types. Whether you are maintaining the original injectors or have upgraded, select the appropriate adapters. This is particularly important if you are using OBD1 or OBD2 connectors but require a different injector type to match your 1990 Honda Prelude Si’s engine modifications.
Alternator Adapters: Currently, we offer OBD0/1 to OBD2 alternator adapters. For your 1990 Honda Prelude Si OBD2, which may have an OBD1 alternator setup, ensure you choose the OBD1 alternator type for your engine harness. Adapters can then be used for injectors and distributor if necessary, streamlining your electrical system’s compatibility.
Charge Harness: You have a choice regarding the charge harness configuration:
- Non-separated charge harness: This option integrates the Starter & Alternator leads into the fuse box. For those not running a separate Alternator power lead, adding this option is recommended. This simplifies wiring and ensures a robust power supply to your system.
- Separated charge harness (for battery relocation): If you are relocating your battery, pairing this harness with our Starter Fuse box lead simplifies your power distribution. A heavy gauge wire run from your 12v+ battery terminal to the starter will provide the necessary 12v+ power to your fuse box.
Investing in our Mil-Spec engine harness is a proactive step in maintaining and enhancing your 1990 Honda Prelude Si OBD2. It not only provides superior performance and reliability but also future-proofs your classic vehicle’s electrical system against the rigors of time and use.
