Help with aftermarket stereo receiver and factory Antenna
 

Hello everyone! I need help with figuring out how I can make the factory power antenna to work with my aftermarket Pioneer DDin FH_P8000BT unit. The wire harness that came with the new receiver has a "blue/white" remote cable. The manual says to connect the amp remote cable or the auto-antenna relay control terminal (max. 300 mA 12V DC). Currently I have both of my amps remote cables connected to this cable. My questions are: Can I safely connect the antenna relay to this cable eventhough I've already have two other items connected to it? Second, Where is the antenna relay located on my 1997 4Runner SR5? and lastly, Which cable from the mentioned antenna relay do I have to splice and connect with the receiver's "blue/white" remote cable? Thanks!!!

If you are that concerned about over drawing the blue-white power feed just drive a relay with it and let the output of the relay drive any and all other "power on" devices. FYI- I don't have an antenna but I drive 3 power amps and an EQ from mine with no problems.
My motto?
"when in doubt, RELAY it out"

Okay Thanks worshipmentor!!!
