Power Antenna Question Options

[asalamay]

I'm replacing my factory power antenna with an aftermarket one. I have it mounted but the question I have is how do I hook up the wires. There are 6 wires running to the factory antenna relay and 2 running to the antenna. My aftermarket only has 3 wires, black for ground, red for power and blue for switched.

Do I have to use the factory relay, not sure if it does anything else, especially since it has 6 wires?

If not what wires do I tap into, I figure I can put the ground directly to the body, but which wires are the power and switch from the radio.

It may be helpful if anyone had a wiring diagram.
