Help wanted, please.
I am rewiring my Kenwood nav unit to eliminate the Scosche adapter and OEM socket by wiring directly to the OEM harness There is little room behind the unit and the firewall insulation and the Scosche adapter and OEM socket take up a lot of room.
Easier said than done when you have little knowledge of the wiring of the speakers.
The OEM plug has four wires to it and the Kenwood plug has eight just like the amplifier, the question for anyone who knows is how do I run eight wires to the OEM four wires. I guess I twist some together like the OEM wiring schematic attached. See also the Kenwood schematic.
Thanks for any help.
