1. I think using the original connector is a great idea. XEENITH, What did you do with the other two wires? I see only one of them is used?
Don't invent problems that don't exist, he clearly pointed out you only use the one wire, the others are not required, hence they are not documented.
If you want more information for whatever reason, the 3 wires on that plug:
- Black: ground
- Green/Yellow: 12v lead of the radio telling the antenna: "hey i'm on, go up!". This wire shows 12v when AM or FM is the active source, 0v when the radio is on another source or powered off.
- White: constant power (shows 12v all the time) to actually power the motor to go up or retract
The S2000 antenna doesn't move up or down, so you don't need the white wire since there is no motor that needs power.
The green/yellow from the radio: this is the wire you want to the lead of the S2000 antenna as it powers the booster built into the antenna. The booster needs to be grounded to the car to work just like any other electronics, so that leads to:
The ground wire is not used because it is kind of redundant because the (Integra) antenna body is bolted to the body of the car and as a result: it's already grounded. In the write up above, the OP uses a metal strap to hold the metal body of the S2000 antenna to the body of the car.
