Okay , i bought a head unit a couple of months ago and i matched the wire colors and when i plugged it into the factory harness the battery drained over night . After install the backlight for the stereo was on. when i shut the ignition off and pulled the key out the backlight was still on which means there was still power getting to the head unit ... What was done wrong ... and what can i do to fix it

 

did u buy a plug and play harness for the rangers factory one? or did you splice into the rangers factory harness?

 

plug and play ... the one you wire to the headunit then plug into the factory harness

 

sounds like u wired the constant power wire (yellow) up to the remote wire...(red or blue) for the stereo

 

i matched all the colors ... i wired the yellow to the yellow but im like WTF happened lol

 

what i would do is start all over

 

i had one like that man that didnt work righ.t so i just took it off ,and spliced into the factory harness instead, and never looked back lol. thats why i asked if you bought plug and play.

 

i really dont want to start all over again or cut into the wires ...... do you think if i swithed the wires and connected red to yellow the problem might be fixed... if its wired right and doesnt work i wonder if i wire it wrong and it might work lol

 

pic of your wire harness

 

im nowhere near my truck ill put one up when i go to the station

 

Did your new harness come with a color code indicator? Sounds like you just eyeballed it, I would take a second look cuz you probably have something backwards.

 

you didn't happen to get the harness from crutchfield did you? Same problem I have with my new head unit, only I'm at swa and dont need the truck while I'm gone so I just disconnected the batt til I get home week after next.

I have the wiring harness color code with me and the plug and play color code from crutchfield and they say they are fine, what I would really like is a wiring schematic for the 2003 edge dash with the factory 6disc radio if anyone has it. I may get an answer for both of us before I get home. otherwise I will be sure to check back to this one often..

 

You can't just match the colors. Get a wiring diagram and compare it to the wires of stereo harness and wire it up that way.

 

im not sure if it was crutchfeild or not .. im prettyu sure it wasnt though .... i followed the wiring diagram and it just so happened that the colors matched ...

 

Probably wired your Power-On (switched 12+) into your Memory (constant 12+) and vise-versa.

 

Double check your wires. The plug into the truck harness should have the wires labeled
