Enables your new receiver to operate the factory OEM power antenna. Connects to the wiring inside your dash. Simply splice the color-coded wires on this relay to the wires from your aftermarket radio and your Crutchfield receiver wire harness. (You can connect the relay to your new receiver on your work bench or kitchen table. Soldering is best, crimping is also very popular — see "Accessories").

Crutchfield Customer Review (What's this?)

It's a relay that's for sure. There's not really much to review on this, it just switches the ground on/off for the backwards wired Mazda antenna. I do like that it came with a socket for the relay to plug into instead of just quick disconnects.

Pros: Comes with a socket for the relay

Cons: None
