HOW CAN I DETERMINE WHAT WIRES IN HARNESS TO USE FOR TWO WIRE AUTO ANTENNA REPLACEMENT FOR TOYOTA CELICA GT 1990. THE NEW ANTENNA HAS TWO LEADS, BLUE AND RED. ONE POWERED, THE OTHER HOT. THE WIRING HARNESS HAS A HOST OF DIFFERENT WIRES THAT APPARENTLY WENT TO RELAYS MOTORS ETC OF OEM ANTENNA. I HAVE SIMPLER REPLACEMENT. NEED ONLY THE COLORS OF TWO WIRES: ONE FOR THE POWER, E.G. WHEN KEY IS ON AND THE OTHER FOR A HOT LEAD. WHICH COLORED WIRES IN THE 1990 HARNESS GOING TO THE AUTO ANTENNA DO I USE??? THANKS.
Sounds simple
placement of antenna is important this will determine which wires to use
most antenas are in the trunk of vehicle with a wire clip to connect or disconnect
tools needed
test light
find your wire clip running from old antena this will be where test light will be used one side of clip is full powered the other is key powered find good ground tip the test light on first prong light stays on this is full power other will be key powered
now your looking for the simple color wires ok on the back of your sterio there is an atenna wire which is blue this will power on only when sterio is on the other wire
you use test light to find without key in take your test light and find a permannent powered full on wire hot supply then connect antenna into these 2 things
at top the reason i mentioned this is cause the old power antena you can find the right leads in the trunk area where new antenna going to be placed with the test light you might need a second person to help you testing wires you in the back and them in the front turning the key on when you need it it makes things simpler with 2 people
i hope this helped you in your quest for knowledge
