What are the 1994 Ford Ranger Extra Cab stereo wiring color codes?

Answer 1

Taken from the sticker on the harness sockets that attach into the standard (non-premium) factory head unit on my 1994 Ford Ranger Extra Cab.

Black Connector that feeds the speakers (not the gray, which feeds power) when looking at the eight slots in the socket with the index tab in the lower right corner:

Reading right to left from index tab:

#1 Left Front Feed ( + POS) -- Orange with green stripe (wire closest to index tab)

#2 Left Front ground ( - NEG) -- Light Blue w/ white stripe

#3 Left Rear Feed ( + POS) -- Pink w/light green stripe

#4 Left Rear ground ( - NEG) -- Tan w/ yellow stripe

#5 Right Front Feed ( + POS) -- White / light green stripe

#6 Right Front ground ( - NEG) -- Dark Green w/ orange stripe

#7 Right Rear Feed ( + POS) -- Orange w/ red stripe

#8 Right Rear ground ( - NEG) -- Black w/ white stripe

Gray Power Connector Socket:

When looking at the eight slots with the index tab in the upper right corner:

Reading from right to left, starting at index tab end:

#1 (closest to tab): Marked "Memory Feed" -- Light Green w/ yellow stripe (this is continuous power even when ignition is off)

#2 Marked "Veh Chassis Gnd" -- Black

#3 Marked "Radio Power Feed" -- Yellow w/ black stripe (this turns on with ignition)

#4 Marked "Panel Illumination" -- Light blue w/ red stripe (Dimmer? not sure)

#5 empty -- no wire

#6 Marked "Radio Ground" -- Black w/ light green stripe

#7 empty -- no wire

#8 empty -- no wire

I don't know the difference between "Radio Ground" and "Vehicle Chassis Ground."

My Pioneer DEH-P7100BT called only for "vehicle chassis ground" so I connected its black wire to Pin 2 chassis ground, after initially connecting to Pin 3 "radio ground." Both worked.
