I think I already have that harness for the black speaker plug.sorry for so many msgs but if you follow those instructions and it does not turn on then check your fuse located under the hood in that fuse box. actually disconnect your battery while you do all this to avoid that issue
But will all my speakers power? The dealer I bought my car from had an aftermarket radio but no deck. Previous owner had the door speakers switched (the top tweeter plug was plugged into the bottom speaker, and the bottom speaker plug was plugged into the top tweeter) does that make sense?
I switched them back to normal. But Before I switched them back, I bought an aftermarket radio and hooked it up with the harness. I only got sound out of the bottom speakers in the front? Do u think since I changed the plugs back to normal now all speakers will work?
