I have this idea to wire up a blutooth reciever directly to the radio head unit through the wiring harness that connected it to the CD player. Heres a pic of the connector that plugs into the head unit side . How would I go about figuring out which of these color wires does what?
Hey Benton thanks for the reply. I have seen this wiring diagram and I believe it to be referring to the wiring harness that comes out of the stereo and sends signal to the all of the speakers. I believe this because the colors on that diagram match up with that wiring harness and not the one I have pictured. I am looking for information on the one that connects the CD player to the stereo unit.
First you will need to identify the power connections by doing the fallowing.
Step 1;
use a test light to identify the B+, ignition + and the GND wires.
Step 2;
connect the new harness to these wires.
step 3
Next identify what speaker pair of wires go to which speaker
step 1;
isolate one pair of wires by color code. black & black w/ white stripe is one pair. etc
step 2
use a AA battery to very quickly tap these pairs of wires to & listen to what speaker makes noise.
step 3
connect the speaker wires of the speaker that made noise to the corresponding wires on the new stereo harness.
step 4 repeat step 3 until all speaker wires are identified & connections are made.
this entire process takes approximately 30 minutes to complete.
I have plans to do the exact same thing on my '98 Trooper. I had an '06 Mazda 3 that had an extra input to the factory stereo for a CD Player and found a kit to install an Aux input instead. I was hoping that the same thing would be possible with the Trooper, but I haven't found a wiring diagram anywhere for this connector. It seems like the stereo is always treated as a single unit with or without the CD player attached, and only the connection from the head unit to the rest of the car is described.
I would kind of assume/hope that one of these would be a line-level output from the CD player, but maybe that would be too easy.
If you want to take the easy route, these modern bluetooth FM transmitters are surprisingly good and cost next to nothing. You could probably get a small one and just give it some switched 12v and hide it under the dash somewhere if you want a more stealth approach.
