94 F150 stock radio Bluetooth mod

[ayriggins]

I have a 1994 Ford F150 with a stock radio that includes a tape player that I'm currently modifying with a Bluetooth receiver. My plan is to splice into the tape deck. I was able to get power to the Bluetooth receiver, but I'm struggling to get sound out of it. I removed all of the springs for the tape deck so that it always thinks there is a tape in the deck. The receiver has the red and white rca outputs, which I cut off to expose the wires. In each there is a white and red wire. I only used the white wire for both. I spliced them into wires that go into a harness for the tape deck that is labeled TAPIN, and also shows an L and a R for the red and white wires. My guess is that I'm not spliced into the correct wires for the sound. I'm including pictures that will hopefully give a clear picture.
