Third Gen Celica Stereo Wiring 1981–1985

Fourth Gen Celica Stereo Wiring 1985–1989

The changes to the Celica made improvements to the center console. The changes to the dashboard make upgrading your Celica stereo slightly more difficult. This car stereo wiring diagram below covers the Toyota Celica from 1985 to 1989.

Fifth Gen Celica Stereo Wiring 1989–1993

The dash in this year range of Celica underwent quite a few changes. Gone are the boxier single DIN factory stereos, to be replaced with the first of Celica stereo that’s mounted into the center console. You will need to remove the inner panels on both the driver and passenger side to access the factory Celica radio.

Because this Celica radio doesn’t have a trigger wire for the amplifier, you are best served by wiring it into the ignition switch.

The front Celica speakers are still in the dash, which can be troublesome. These speakers measure 4 ” in size but you can connect the front Celica speakers by using our car audio wiring guide below.

The sizing for this Celica stereo opening can fit a double DIN stereo or single DIN with a pocket. Most Celica stereo install will require a radio mounting bracket or kit.

Otherwise known as the T180 Celica the rear Toyota speakers left the rear deck and are mounted into the rear panels. This makes install slightly more difficult as you will need to remove the back seats and paneling to access the Celica speakers.

Sixth Gen Celica Stereo Wiring 1993–1999

The familiar front fascia of the sixth Celica are undeniably Toyota, and the interior also received a highly stylized make over.

The changes to the dashboard wrapped the console around the driver. This Celica stereo install requires that you remove all the center console paneling to access the radio.

Once you have the double DIN stereo removed, you may need a radio install kit. This depends on whether or not you are installing a single DIN or a stereo with a popup face.

If that’s the case you’ll need a stereo install kit to make sure that the face works or you can fit the single DIN stereo over a DIN sized pocket.

Seventh Gen Celica Stereo Wiring 1999–2006

The last Celica stereo is in the Toyota center console and much like the last generation will require you to remove the entire console.

None of the Celica factory stereo units came with a dimmer wire or dial, so if that’s a big deal for you an inline dial can be wired in.

The incline of the Celica stereo and double DIN factory stereo makes a motorized face a nice choice.

Most aftermarket Celica stereo systems won’t run into the custom pocket or the popup lid. But if your Celica stereo has a flip up monitor or uses a touchscreen navigation system, you need brackets that will clear the flip up pocket lid.

  1. Hello ProStreetOnline

    A great reference – thank you. For the 7th generation Celica (T230), have you got a wiring diagram for the optional subwoofer fitted to some cars? Having purchased a sub from a scrap dealer (the sub is in excellent condition, the rest of the car was not), all I need now is to understand the wiring and then I can put together a suitable harness and install it. I purchased it online, I did not have opportunity to inspect the wiring.

    Hope to hear from you soon – Many thanks

    • Hi Lisa, did you ever find a wiring diagram for the sub? I also just got one and I’m trying to work it out. There seems to be very little information about it anywhere!

  2. Hi Lisa,
    Did you ever find the wiring diagram for this? I just bought one of these subs and i’m struggling to find any information about it! Many thanks,
    Clint
