The ECU (engine control unit), also called the ECM, on most 1995 Nissan pickups sits inside the cabin on the passenger side—typically behind the glove box or on the passenger-side kick panel. In some configurations, a version of the ECU may be mounted in the engine bay near the firewall, but interior mounting is far more common for this model year.
Typical locations inside the cabin
The following interior spots are the most common for the 1995 D21 Hardbody pickup with KA-series engines. Look here first before checking the engine bay.
- Behind the glove box, mounted to a bracket on the dash or firewall area on the passenger side.
- On the passenger-side kick panel, accessible after removing a lower dash panel or trim cover.
If you locate the ECU behind the glove box or on the kick panel, you’ll typically see a rectangular electronic control module with a multi-pin connector feeding the wiring harness.
Engine bay mounting (less common)
In some configurations or aftermarket modifications, an ECU/ECM may be placed in the engine bay near the firewall. This is far less common for the 1995 pickup but can occur in certain trims or when owners replace components and relocate modules.
- Near the firewall on the passenger side, sometimes attached to the inner fender or a small bracket in the engine bay.
- In rare cases, tucked under or beside components like the brake booster or air intake path, depending on how the harness was routed.
For engine-bay placements, the connectors are still the giveaway—you’ll see the same large multi-pin plug and related harnesses, but access may require relocating hoses or components to reach the module.
How to locate with a quick check
To identify the ECU quickly, start by inspecting the passenger-side interior area. Open the glove box and look up and to the right for a rectangular black module mounted to a metal bracket. If nothing is visible there, check the kick panel by removing the plastic trim panel on the lower passenger side.
Summary
For a 1995 Nissan pickup, expect the ECU to be inside the cabin on the passenger side—usually behind the glove box or on the kick panel. Engine-bay mounting is possible but uncommon for this model year. When in doubt, refer to the service manual for your exact VIN/engine variant, or consult a Nissan technician to confirm the precise location.
Where is the ECU on a 1995 Nissan Pathfinder?
To retrieve ECU error codes for 87-95 Pathfinders and hard body pickups, the ECU is located under the passenger's side seat. You can access it by sliding the seat all the way forward and removing the plastic cover from the ECU. Alternatively, removing the seat can make access easier.

Where is the ECU module located?
engine compartment
In modern vehicles, the main engine control computer (ECU) is typically located in the engine compartment. In vehicles from the 1980s and 1990s, some ECUs were placed inside the passenger compartment, with wiring connected through the bulkhead.
