juss lmk wht to check, how to check it, how to fix it. i dont mind having a toggle switch for the backlights but i dont know how to do that because of the dimmer function.

i appreciate any help.

Take the head unit back out and restore the wiring to it's original condition. Grab a harness adapter from your favorite sound shop or auto parts store and re-install the head unit.

how does restoring the wiring fix my dash problem?

thats like taking gas and pooring it on your floor, lighting it, then saying well if i take back the lighter to the store and mop up the gas itll bring my house back...

SeriousOffroad

Because based on your post the problem began after you installed the head unit. Makes sense that you made a mistake.

Feel free to set your rig on fire...if you think it will help.

check fuses 15,17 & 19. If those are fine then get deeper into it.

i juss figure whatever damage that was cause by the h/u is done. i juss need help with finding what happened.

SeriousOffroad

And the only way to know is to pull the head uint and double check your wiring.

BenjiBlood

so somewhere down the wires it merges with the dashlights?

SeriousOffroad

Yes, the dash light power circuit also sends power to the radio illumination circuit.

but since its an aftermarket h/u i didnt use the illumination lead.

i just went out and tested the three listed fuses... fuse nineteen isnt firing.

BenjiBlood

how could i fix my dead fuse problem???

SeriousOffroad

If the new fuse blows immediately then you've got a short to ground.

the fuse slot isnt giving off any juice.
