Aftermarket Head unit...

[Yarisaur]

Can you install a aftermarket one and still utilize the factory AUX port? by possibly wiring it to the new unit?? is this possible and if so dose anyone have a write up?

if the new head unit has the inputs you can do it, might have to re wire to RCA's
or you can just get 1/8 stereo jack to rca cable and feed it through the whole where the Aux input is.

Okay so i would just have to wire in the aux to the place on the deck were the aux wires would be on the deck?

Yes, the jack is just that a jack a 1/8 stereo jack.

Yes, I have done exactly this -- factory AUX to aftermarket HU with stereo jack, but I didn't make a write-up.

The factory AUX port is split into four wires and delivered to the head unit in via four pin connector. See this diagram on the connector. I do think it maybe changed on more recent models... maybe someone knows more?

In any case, all you have to do is properly solder those four wires (two ground, one right, one left) to a 1/8" stereo plug, maybe fill it with some high-temp hot glue for stability/insulation, and you are done. I used a stereo plug from Radio Shack (Catalog #: 274-284), soldered on four wires, jammed them into the correct pins in the four pin connector and taped it up tightly. You could connect it "properly," of course, I just didn't want to alter the connector in any way in case I needed or wanted to put back in the stock HU.
