Does this harness work if you have the two extra tweeter speakers? It says it is for 4 speaker so I'm not sure if it handles the tweeters.

I have the 6-speaker system in my 2002 Tundra AC and installed the JVC KW-R910BT HU which required the removal of the OEM amp. I wired up this adapter to the HU's harness and then plugged it directly into the truck's two connectors. ALL speakers produce sound. The tweeters are simply on the same circuit as the front door speakers.

What gauge wire is this? I want to use the correct crimp cap size. Thank you.

The wires on this harness are 16awg, not 18 or 22. I compared them side by side at a store carrying all sizes

what is the smaller 4 wire harness for?

Its for the L&R rear speaker connections in the 4 door truck.

does it include the dimmer wire

The orange/white wire is listed on the Metro package as "dimmer", the orange wire (no stripe) is listed as "illumination."

Great for my toyota echo and rixow bluetooth stereo

Installed on the $30 Rixow bluetooth stereo also from amazon. Didn’t want to ruin the stock wiring on my toyota echo, so i got a harness. stripped the ends of the wires from the meters harness and my rixow stereo harness, and wrapped the wiring together and electrical taped them right. Only wire i had to cover up was orange as there was no orange wire on my rixow stereo. But it worked great, just plugged harness to my car and rixow harness to the stereo, tested and worked great.
