These harnesses allow you to plug your new speakers into the factory connectors present in your vehicle's speaker openings.

Note: Some aftermarket speakers have terminals that are wider than this harness's slide-on connectors. You may need to widen the harness's female slide-on connectors, or use the slide terminals that may be included with the speakers. If you need to connect your new speaker's connectors to the harness, soldering is best, and crimping is also very popular — see "Accessories."

Includes Crutchfield's 60-Day Total Satisfaction Guarantee

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so, then check here for a list of parts. You can also call an Advisor for more information.

Features

Crutchfield Speaker Harness: Crutchfield speaker harnesses prevent you from having to cut your vehicle's factory speaker plugs when replacing your factory speakers with aftermarket car speakers. The Crutchfield speaker harness features two female quick-slide connectors on one end to attach directly to your new aftermarket car speakers & a proprietary Molex connector on the other end that connects to your vehicle's factory speaker plug.

Quick-Slide Connectors: The Crutchfield speaker harness is equipped with a large (positive) & small (negative) female quick-slide terminal. These quick-slide terminals fit directly onto most aftermarket car stereo speaker terminals (slight crimping may be required). In rare cases that the quick-slide terminals do not fit your car speaker terminals, you will need to solder the Crutchfield speaker harness to your aftermarket speaker's terminals or replace the quick-slide connectors on the Crutchfield speaker harness with the correct size terminal.

Note: Installation tools, hardware, & accessories are not included & sold separately. Please see the Accessories tab for recommendations & availability.

Quick-Slide Terminal Measurements: The positive female quick-slide terminal measures 0.205" (inner width), while the negative female quick-slide terminal measures 0.115" (inner width).

Wire Code Chart: Two identical Crutchfield speaker harnesses are included.

No Matching to 2002 Sequoia

Written By Anonymous, MV, CA on Monday, October 27, 2014

Crutchfield Customer Review (What's this?)

It didn't fit to 2002 Sequoia speaker connection and didn't match to it. I didn't know how they advertised that fit to Toyota Sequoia on Crutchfield webpage. Do they really know their stuff? I gave 1 star for it didn't have 0 star.

Crutchfield response on Tuesday, October 28, 2014 This is one of the reasons why we suggest that customers give us a call before ordering, just to make sure they're getting the correct gear. The 2002 Sequoia is one of those oddball vehicles that use different speaker connectors in the front doors and the rear doors. This harness will work for replacing the front speakers, but not the rear door speakers. Give us a call and we'll send you the rear door harness if that's what you need.

Installing new in-dash speakers was so easy with this wiring harness. And the sound blows away what used to be in the dash from the factory.

Pros: Easy Installation without crimping or soldering.
