Audio Systems: Power Antenna /Retro-Fit, power antenna, purple wire

Question
Salvaged antenna of unknown origin.  Only part #'s found on it are PAP-231-100 & below that is N 32 08 080889.  Have the harness and relay etc.  But I need to know where/how to make the connections to install in a Ford Escort Zx2.  The power is purple wire w/green stripe and other wire looks like plain white. However coming out of the relay box the wires are brown w/white stripe, green w/yellow stripe, yellow w/green stripe, plain white, & plain black.  Any help or assistance you could provide would be most appreciated.  Thank you.

Answer
provide a good ground and power the rest of the cables
most of the times there is a total of 2 or 3 cables only
again ground the antenna find the ground wire and send 12 volts possitive to all the other cables, now unplug cables one by one if the antenna close the wire that you remove the power will be your remote cable the cable that stays with 12volt is your ignition

if the antenna stay out open
power all the cables again and unplug one by one on a diferent order
untill you find the triger wire

good luck
