DIY $5.99 Aux-In cable: OEM headunit

SJwrx · 02-08-2013, 02:19 AM

Hello NASIOC,
So I'm a thrifty bugger, always willing to invest when needed... but $60+ for an Aux-In is a little steep. I can't speak for this works for 'ALL' head units, but it definitely works on a 2002-2003 WRX head unit.

You're going to have to take the headunit out, pull the CD unit out and find the triangle board (its about 10 screws in, no worries)... I did it with 1/2 a 6-pack in me

Go to Radioshack, or anywhere you have a regular 1/8" Aux-In cable handy and cut the NON-MALE end off. You'll find 3 wires:

Red w/ copper wires- Right channel
Black w/ copper wires - Left channel
Black w/ """SILVER""" wires - AUX GROUND!!! (ie not L channel)

Here is a pic of what you'd like to accomplish:

Red wire(copper) -to- RHC (which means right hand channel)
Black wire (copper) - to LHC (which means left hand channel)
Black wire (SILVER) -to- AU GND (which means auxiliary ground)

The going theory is that you MUST run a blank (silent) audio CD... I run the GF's Beastie Boys "Licensed to Ill" and I have no interference...but do as you wish.

Cheers all!

-Richard

PS... If anyone wants to send me their headunit to make a full writeup on this, I'd appreciate the chance.

Hi. i would love to give this a try. does it mean that only the cd or the aux in will be playing?

Edit. I found my answer. Thanks.

what happens when you want to play a cd though? still works?

i like that, thats definately pretty crafty. i wonder if it works on a 06 sti, i hate that my year doesnt have the aux and the 07 does...

two sources, one input... you do the math

I did this back in 2002-2003 on my bug eye and this was documented back then, when nasioc was called i-club. Back then though I used a DIN plug rather than soldering anything.

Yep, the Aux "overrides" the CD sound when you plug-in a phone/music player to it. Everything still works 100%.

You 2006 boys already have a write-up, but its the same idea. Left channel, right channel, ground... its just a matter of finding them.
