For a while I’ve been irritated that I could not connect my phone into the stereo in my car. I’ve been using a Satechi BT Ultimate FM transmitter. However since the bird’s aux ports are always hot half the time it blows the fuse in the transmitter. I had gotten in the habit of keeping a half dozen or so fuses around to fix the transmitter. Problem is…these fuses are a bit over a buck each. So I probably feed it 20+ a month in fuses. I thought it time I do something about that.
I went to my local Radio Shack and picked up a 1/8″ panel mount jack that was a 3 conductor closed circuit. I was determined to install this in the car so I could use my modern tech with the old OEM head unit without spending hundreds and hundreds on a new unit.
I pulled the head unit and started to break it down. What I found was not as expected. Wires were normally white and black. I had everything in red. At least they were keeping in the pontiac spirit.
A little research later and I found out that despite the color, the pin out is still the same. So I snipped off the left channel and pulled out a piece of CAT5 to use as an extention. Here is a nice soldering of the left channel cables.
After heat wrapping those connections I did the same to the right channel resulting in this.
Once I put everything back in it’s place I buttoned up the head unit and went to work on the other end of the cable. I used the switch and tagged all the appropriate items on the tabs then soldered them into place.
I slapped the unit hack in the car and plugged the phone into it with pandora running. I was so estatic that I sat there almost an hour listening to it before I decided to come back in.
Right now the cable is just hanging out in front of everything but when I have the time I need to tuck it up and hide the connection away.
