I posted this in the TTA section on TB.com and a member requested a "how to" on it - so I thought I'd post it here since other 3rd gens have this radio or a similar one. I know it can be done with a relay, other ways, etc., but I wanted to maintain an unmolested stocker without input jacks in the front, etc., and maintain my steering wheel controls

What you’ll need: 3.5 mm female panel mount stereo jack, I used one with a switch, but any type will do, mini-toggle switch (to switch from radio to MP3), 24 awg wire (I used 3 wire Belden cable for the stereo jack), soldering iron, electrical tape / shrink wrap, small nut drivers, 3.5mm male to male cable (I used a 1' piece) to attach MP3 or iPod.

Remove two 1/4" and one 3/16” nuts from top of the stereo and slide back the upper portion of deck toward the rear of the unit to expose the tape deck.



Gently remove the larger of the two connectors by un-fastening the side clips



At the back of the pin connector you'll see where the audio wires connect in their individual slots. I piggy-backed the input wires at this point by removing the existing wires and putting the input wires (un-sheathed) in the appropriate slot and re-connecting the existing wires by pushing them back with a small flat blade screwdriver.



(Pin 15 - 14v) and (Pin 12 - "T"-On) wires go to the mini-toggle switch
(Pin 8 - L-Aud),(Pin 9 - R-Aud), and (Pin 14 - H-Ground) wires go to the 3.5mm stereo jack.

I ran the wires out the hole in the back of the deck by the plastic mounting pin and pulled them over to mount in the ash tray.


Where the wires get soldered to the switched 3.5mm stereo jack I used. If you use another style/type follow schematic or ring it out with a meter.



Toggle and Input jack wired up.



3.5mm jack and toggle installed in ashtray, MP3 attached to cigarette lighter USB charger.



Note: You can pull toggle and 3.5mm socket up into the ashtray via the slot in the front and leave them unmounted - I drilled the back to mount them. If you do this you'll have to grind (dremel) some plastic from the backside of the ashtray to mount the 3.5mm socket as the neck is not long enough to go through the ashtray and I think this will hold true for most types.

 

really nicely detailed install. should help a few of the guys around here looking to keep their stock decks while still being able to take more than tapes with them

 

Good write-up, I have a Pontiac Trans Sport radio that looks identical but I couldn't differentiate the wires. They share nothing with the earlier units.

 

Would this work on a radio out of a camaro? the kind with electronic tuning? or do you know? Just wondering because i remember a while back reading some type of write up and it didn't look nearly this simple

Cant even remember if it even has a tape player, but i don't believe it does.

 

Don't honestly know. This deck is the same unit that was pretty much standard for 89' GTA's and from my understanding will work on similar 3 piece decks.

When doing my research for this others snipped the tape deck wires (R & L sides) and attached the MP3 inputs at that point, thus removing the funtionality of the tape player. Then used a switch or relay to jump the tape deck N/O switch to go from radio to MP3.

 

This is what I did to my UU6 radio : https://www.thirdgen.org/forums/car-...ary-input.html

 

Did you have a 5 prong connector just like that one? Or did you just take the colours from another connector with those colours=more? hope that makes sense..

Edit:
Nevermind, tried every way and rewired in every way I thought reasonable. Figures that the delco bose does not work with his "mod"
