I have an amp out of an '05 Tundra Access Cab and am wondering if anyone can tell/show me the pinout designations of this thing. This is a model # 86280-0C061. I was hoping to wire it up to my '04 JBL 6-disc head unit that has the standard 20-pin amp connector.
There are two connectors on this amp. One is a 24-pin with small blades and the other is a 12-pin connector.
Here's a pic of the connectors on the amp:

And heres the amp model #:

And lastly..here's the back of my HU:

Am I still S.O.L.?

Won't a digital amp work on a non-digital HU as long as the corresponding wires are in the appropriate places?
Besides, aren't aftermarket amps digital and don't they work on factory head units just fine?

Thanx for the help,
Bud

Yes, digital or D-Class amplifiers are capable of working with a "non-digital" HU, as the signal into MOST all aftermarket car audio amplifiers is an analog signal sent through RCA cables. It is feasable for it to work, however the main problem you are going to have is finding the input pin diagrams and connectors to use for the amplifier.

Finding the output configuration of the stock HU will either take some testing, or easier method may be to purchase a 71-Series Metra wiring harness for your vehicle, which is intended to plug into the back of your stock radio. Because Metra is an aftermarket manufacturer the harness has the aftermarket standard wiring which will allow you to easily find the input/output wiring of the HU.

I see look around for a totaled vehicle and cut the plugs out andm ake a harness into your stock ahrness and your truck should have a stock amp as well or atleast be wired for one. look around since they are so close in years one would think its the same

WAIT!! First off, it is a JBL amp out of the 05 Tundra, then the amp is turned on digitally and will not work with your 04 Radio.
