I know I can wire these up using the factory harness in each seat. Is there a special (proper) way I should go about doing it so I don't 1) short anything out 2) ruin my factory harness.
I'm not much of an electrical guy so I need a little help Thanks in advance
If you short out your speaker wire you'll just stop hearing any music at all. And once you fix the short, the music will come back. It's not like you'll blow fuses or anything.
Years ago, I had the music suddenly stop on my 97. But if I slid the seat all the way back, it would come back. So I took the seat out and poked around. The headrest speaker wire on the driver's seat had become caught in the seat slider teeth. It got all mangled. When I untangled and taped the wires, I never had a shorting out problem again. So I ran the speaker wire up into one of the holes in the bottom of the seat pan, along the bottom of the seat, and out the very front of the seat cushion. Never got the wire caught again.
The wiring is pretty forgiving. Don't be afraid.
