Known as the N60 the early models of the 4Runner are still sought after for being cheap on the go trucks. There were two variations to the constant power wire for this generation of Toyota truck. If you are in doubt when installing your 4Runner stereo or amp, simply bypass the constant and go straight to the ignition column.

Upgrading the front 4Runner speakers was a bit of a chore in this early model. Mounted into the dash it was tricky to access the speaker panels in the earlier 4Runner trucks. This is the first segment to our 4Runner stereo wiring guide.

Second Gen 4Runner stereo wiring 1989–1995

The next generation of Toyota 4Runner stereo came in two different flavors. Halfway through this model, it upgraded from the N120 to the N130 4Runner. Still getting your 4Runner stereo install done in this truck is easy to do given the basic DIN form factor.

Upgrading your front 4Runner speaker still meant you had to access them through the dash however. Installing a single DIN 4Runner radio meant that you needed an install kit containing a single DIN pocket or spacer.

The N180 4Runner made big changes to the interior of the truck. Gone was the simple layout and center console, replaced by side panels that needed to be removed to gain access to the radio screws.

Still installing any DIN sized 4Runner stereo was simple to do. Most aftermarket stereos will not require a 4Runner stereo install kit.

Keep in mind however that if you want to use a navigation system with a flip up screen, chances are you will need proper mounting brackets.

That’s because of the 4Runner stereo mounting position in relation to the climate controls. Without the right mounting brackets chances are your flip up stereo may run into the dashboard.

Fourth Gen 4Runner stereo wiring 2002–2009

The design changes and upgrades to the 4Runner of this generation left a lot of car audio enthusiasts high and dry.

While you can still upgrade to a double DIN design, you will need customized brackets to make sure the 4Runner installs right. You can of course choose to run a 4Runner stereo install wiring harness, which eliminates a ton of guessing and hunting for speaker wires.

    • Hi Matt, thanks for reading

      For the remote amplifier wire, or switched power you can always use the Toyota 4Runner ignition switch, located in your steering column. Hope that helps!
