HI,

I have an 03 Ranger that has a hacked up wiring harness. I have followed the diagram posted at the Ford Ranger Radio Wiring Diagram at the link https://www.therangerstation.com/how-to/interior-and-interior-electronics/ford-ranger-radio-wiring-diagrams/ but am not having any luck.

I can not get the stereo to power on. If i read the chart right my

Battery/power should equal light green/violet
Fused Ignittion should be yellow/black (this seems right as when i put a test light on this one it only light ups during ignition)
Ground should be black

I'm a bit confused though as this "specific to 2003" https://therangerstation.com/tech_library/pdf_documents/2003_Ranger_Radio_Wiring.pdf shows that

Battery/power is still light green vioelet
fused ignition list yellow/black and red/black
ground list black and black/light green.

Do i need to pigtail those grounds and fused ignitions together?

Thanks for any help offered!

You don't need the Red/black wire, that MUTES the radio when starting the engine

The light green/purple powers the system and keeps radio presets and the clock time correct when key is off

The yellow/black wire is the ACC or Key on power, turns radio on

Do NOT tie any of the above together

Yes the Black wire is the ground for the Radios power

The other 2 grounds are for the speakers and amp, both black/light green stripe, yes they can all be grounded together with black wire

If you have a premium sound system there there will be a separate amplifier, that also needs power

Its wiring here: https://therangerstation.com/tech_library/pdf_documents/2003_Ranger_Premium_Radio_Wiring.pdf

Easy to tell the difference, the regular sound system will have one connector, 16 pin
Premium will have TWO connectors, a 16 and an 8 pin
