That 3rd clip is what they call a smart connector. Circuit colaborated with metra to have those harnesses made solely for them. I uesed to work in the Roadshop until the big layoff they had back in Feb. so that's how I know. The other half of that "smart harness" has the aftermarket radio plug on it. It's about another $15 but it saves time soldering wires. IMO cut the smart connector and solder the wires to your radio's harness. If you have anymore ?'s PM me.
