Re: 93 Ford Tempo radio
93 Ford Tempo radio correct Wiring from Service Manual
93 Ford Tempo
The first color is the wire color, the second color is the stripe.
Battery / Memory - Light Green/Yellow
Ignition/Accesory - Yellow/Black
Ground - Black/Green
Illumination - Light Blue/Red (Connected to the Dimmer portion of the switch so radio lights will dim with switch)
The orange/black wire is described below:
Panel dimming is controlled by the instrument panel dimming switch. A variable voltage is applied through the 19 (LB/R) wire to control the brightness of the panel lamps.
The display's brightness is controlled by the Main Light Switch. When the park lamps are turned on, battery voltage is applied to the Radio through the 484 (O/BK) wire, and the display dims. When the park lamps are turned off, voltage is no longer applied to the Radio, and the display brightens.
(Light Blue/Red and Orange/Black both have variable outputs so you could use either one, however, the Light Blue/Red is the designated wire so you could just tape off the Orange/Black)
Note that you may not use the Orange/Black wire for your aftermarket radio.
