2010 FJ Radio in an 2003 4Runner

[03L4RUNNER]

Will it work? Same plugs on the rear of this unit as the 4runner?>

 

[DC runner]

Yes and probably not.

What that means is, you can probably get an adapter somewhere. There were several different speaker variations on the 4th gen runner, with different Head units. I have a JBL system, which includes a factory sub, and as a result I cannot run a stock NON JBL without an adapter or splicing.

If you know anything about wiring, you can hand wire it up. If not, look around for an adapter or a universal plug. Honestly, if you can wire on your own, you can make one that will work.

Tl;DR. Yes, You can make it work. No, it will probably not just mount up. Make your own, or buy an adapter (if they make it).

sorry for the quick question and yes I also have the 6 disk jbl system but i ditched the stock head unit long ago and Currently have an Eclipse HU installed along with a PAC-TATO adapter,

So pretty much you are saying the FJ didnt come with the JBL system?

 

[DC runner]

No. Not at all, what I am saying is that due to the variables involved, you will probably need an adapter.

A 2010 FJ Crusier likely has an entirely different set up vs. a 2003 4runner. It could very well be a JBL system, but it will be a different system...

Make sense?
