2nd Gen Chassis Codes: UE Platform Refresh (Isuzu Rodeo) | Model Years: 1998, 1999, 2000, 2001, and 2002
This page provides the complete 1998–2002 Honda Passport radio wiring diagram for the 2nd generation Passport. Use this guide when installing an aftermarket head unit or troubleshooting your factory stereo in a 1998, 1999, 2000, 2001, or 2002 Honda Passport.
The 2nd generation Passport continued the Honda–Isuzu partnership with a refreshed version of the same Isuzu Rodeo platform. The exterior and interior were updated for 1998 but the underlying architecture — including the radio wiring connector — remained Isuzu-based. The Passport was discontinued after 2002, with Honda later filling the midsize SUV segment with the Pilot. The 2nd gen Passport’s radio replacement process follows the same Isuzu Rodeo adapter requirements as the 1st gen, though the specific adapter part number may vary between the two generations due to connector revisions in the 1998 refresh.

Frequently Asked Questions
What wiring harness adapter fits a 1998–2002 Honda Passport?
The 2nd generation Passport uses an updated Isuzu Rodeo radio connector introduced with the 1998 refresh. Metra 70-1858 Wire Harness Adapter or a compatible Isuzu Rodeo adapter for the 1998–2002 model years is the correct solution. Confirm that the adapter is specifically rated for 1998–2002 Isuzu Rodeo applications rather than the earlier 1994–1997 version, as the connector changed slightly between the two generations. Honda-specific adapters remain incompatible.
Does the 1998–2002 Honda Passport have steering wheel audio controls?
Steering wheel audio controls were not included on the 2nd generation Passport. The steering wheel includes cruise control buttons on EX trims but no audio control functions. No SWC retention interface is needed when replacing the Head Unit in any 1998–2002 Passport. This simplifies the installation significantly since there is no SWC wiring to address.
What size are the front door speakers in a 1998–2002 Honda Passport?
The 2nd generation Passport uses 5 1/4″ Speakers in the front door panels on most configurations. The 1998 refresh did not significantly change the speaker mounting locations or sizes from the 1st gen. Rear speakers are mounted in the rear door panels on 4-door models and in the rear cargo side panels on some configurations. Always measure the factory speaker cutout before ordering replacements, as Isuzu-platform speaker specifications differ from Honda’s own vehicles.
Does the 1998–2002 Honda Passport have a factory Bose audio system?
Some EX trim configurations of the 2nd generation Passport were sold with the optional Bose audio system inherited from the Isuzu Rodeo platform. These vehicles have a factory amplifier and Bose-branded speakers. If your Passport has the Bose system, the factory Amplifier must be bypassed or integrated when replacing the head unit. Without addressing the Bose Amplifier, the new head unit’s output will be very low or distorted.
Where can I find wiring diagrams specific to the 1998–2002 Honda Passport?
Because the 2nd generation Passport is mechanically an Isuzu Rodeo, wiring diagrams for the Isuzu Rodeo of the same model years are directly applicable. Factory service manuals for the Isuzu Rodeo (1998–2002) contain the complete audio wiring diagrams that apply to the Passport. Honda’s own service documentation for this vehicle often references the Isuzu source material. Community resources for the Isuzu Rodeo are also directly relevant for Passport owners working on audio installations.
