in the tech section.
note some wires are specifically called out for 1999-2000 as being reversed for those 2 years

This helped me more than anything but I am still skeptical…

Either the voltmeter suggestion or looking at wire colors at the speaker will answer your question with no ambiguity.

50/50 chance of guessing the right colors. If you get it wrong the first try, 100% chance on the 2nd try.

Yup, I dug out a multimeter and I’ve figured it out, thanks!

This was the correct way for my ‘99. Luckily this was the method I followed before finding the other way.

New speakers front to back with a new stereo is the goal.

You shouldn't need the wire colors for the radio if you're using a proper adapter harness. Also - if you plug in the adapter to the factory wiring, you'd be able to immediately see what crosses to each factory wire from the labeled wires on the adapter.

Here is the correct order. Left wires being positive.
