Came across this mess behind my radio today, anyone know why theres two factory harnesses? If i buy the radio install harnesses from LMR can
i repair this rats nest? Whats the blue box?

Usually don't see the harness for an aftermarket head unit spliced in with the factory connectors still there. Most of the time people either buy the harness adapters that plug in to the factory connectors & connect to the aftermarket harness or just hack the factory connectors off and connect the aftermarket harness to the cut wires. I have the diagrams for a '93 in PDF but not 100% the wire colors are the same so just double check.

And the blue box behind the radio is the airbag module

There are two because of the factory amplifier. I bought a cheap connector and sliced it to the aftermarket harness and removed the amp and amp harness.
