This is how I did my ‘custom’ antenna.
Start out by taking the silver trim around the radio off. Then take the radio out. If you have an antenna plugged in, unplug it now.
Now, take of the dash pad. To do this, there are 4 screws. Two in the defroster vent hole and 1 on either side of the dash. Also, take the boost gauge off. 2 Screws inside the pod and pull the wires out.
I took off the gauge surround piece to make it easier later
I used 40 feet of 18 gauge speaker wire
Separate and strip about 2 inches of one end of the wire.
Twist the 2 stripped sections together.
Now, grab the other end of the wire and fish it up to the dash. I went to the left of the heating control unit and to the right of the gauges.
Pull the wire all the way through, leaving enough coming from the radio bay to work with.
