1st Gen Chassis Codes: UE Platform (Isuzu Rodeo) | Model Years: 1994, 1995, 1996, and 1997
This page contains the complete 1994–1997 Honda Passport radio wiring diagram for the 1st generation Passport. Use this guide when installing an aftermarket head unit or troubleshooting your factory stereo in a 1994, 1995, 1996, or 1997 Honda Passport.
The 1st generation Honda Passport was a rebadged Isuzu Rodeo produced as part of a joint venture between Honda and Isuzu. It shares its platform, body, and most mechanical components — including the radio wiring — with the Isuzu Rodeo of the same era. This means the wiring connector is an Isuzu-pattern connector rather than a standard Honda connector, and Honda-specific harness adapters will not fit. Isuzu Rodeo harness adapters must be used when installing an aftermarket head unit in a 1st gen Passport.

Frequently Asked Questions
Is the 1994–1997 Honda Passport wiring the same as a Honda Accord or Civic?
No. The 1st generation Passport uses Isuzu Rodeo wiring and connectors, not Honda connectors. Honda-branded harness adapters such as those used for the Accord, Civic, or CR-V will not fit. You must use a harness adapter designed for the Isuzu Rodeo of the same era. Metra makes adapters for the Isuzu Rodeo platform that are compatible with the 1st gen Passport’s radio connector.
What wiring harness adapter fits a 1994–1997 Honda Passport?
The 1st generation Passport uses the Isuzu Rodeo radio connector. Look for Isuzu Rodeo harness adapters — Metra 70-1858 Wire Harness Adapter or equivalent Isuzu-pattern adapters are the correct solution for this application. Do not attempt to use Honda-specific adapters, as the connector pin layout and positions differ from all other Honda models sold in this era.
Does the 1994–1997 Honda Passport have a factory amplifier?
Some higher trim configurations of the 1st gen Passport (based on the Isuzu Rodeo LS) included a factory-amplified Bose audio system. If your Passport has Bose-branded speakers or a Bose badge anywhere in the interior, the factory Amplifier is present and must be bypassed or accommodated when replacing the head unit. Non-Bose trims use a passive speaker system driven directly from the head unit.
What size are the factory speakers in a 1994–1997 Honda Passport?
The 1st generation Passport uses speaker sizes inherited from the Isuzu Rodeo platform. Front door speakers are typically 5 1/4″ Speakers and rear speakers vary by body style and trim. As with the wiring, speaker sizing and mounting configurations follow Isuzu Rodeo specifications rather than Honda standards. Confirm the cutout dimensions in your specific door and rear panels before ordering aftermarket replacement speakers.
Can I use Honda radio trim parts in a 1994–1997 Honda Passport?
No. The 1st generation Passport’s center console and radio opening are Isuzu Rodeo components. Honda dash kits and trim rings are not compatible. Use dash kits and installation accessories designed specifically for the Isuzu Rodeo when replacing the radio in a 1st gen Passport. Universal single-DIN or Double-DIN Dash Kit are an alternative when model-specific kits are not available.
