Head Unit antenna wire question ???????????????????????????

[Ali2627]

Hi! So, im not sure what to do here.

I have an antenna wire (blue) to connect. The car wire harness has a blue wire / the radio kit has a blue wire for an antenna. But i ordered another connector that connects to the radio antenna and that also has a blue wire for the antenna. So what would i connect? I was thinking of just mixing all 3 wires together.

(Head unit wire kit) + (Car wire harness) + (Antenna cable adapter kit)

Here is a link of the antenna cable adapter kit that i think i may? need to connect to the car harness and ingore the head unit harness?

If the head unit already had an antenna out why would you buy another adapter. Connect the antenna to the head unit.

The adapter has the connection for the antenna so it can use the OEM harness. And on that harness it has a blue antenna wire but the car wire harness for the radio has a blue wire too for anntenna so it basicly has 2 blue wires and im not sure what to do.

Yep, connect the blue wire on the antenna adapter to the blue wire on the HU. The antennas in hondas are powered on by that blue wire just like an amp turn on.
