Argh! Need help debugging batter/memory cable not having power!

gen2 camry

I bought a new cd player today so i disconnected my old one(i wired it up by cutting the OEM plug off becasue i didn't know you could buy a harness at the time).

We wired it up and turned on ignition and we got nothing.

we wire back up the old deck and we got nothing. my clock doesnt work either, neither does my "door ajar" indicator light on the dash.

however when i take the blue and yellow cable and hold it on the red acc cable, everything comes to life.

i have checked every fuse in the car and they are all fine.

any ideas?

I would suggest you reconnect everything like it was stock, rewire the harness, then buy the correct harness.

The blue and yellow wire need power, to tell everything to turn on, they get that from a wire on the harness, and when you connect it to the acc wire, the one that has 12v all the time, everything powers up.

you could also try wiring the blue to another switched 12v source, like your cig lighter, The yellow one needs to be connected all the time, so it can be left on the red. I BELIEVE.

maybe i didn't explain it right.

i have the RED wire from my HU conencted to the ACC ON oem wire. i have the BLACK wire grounded. i have the YELLOW wire connected to the BLUE/YELLOW oem wire.

nothing pwoers on. but if i touch the BLUE/YELLOW wire to the RED wire, everything powers up.

somethings goofy with your stock wires then. dont know what, but like i said, try hooking the the yellow to another SWITCHED (as in on when the car is on) 12volt source, like the cigerette lighter.

That yellow wire is what the reciever uses to know when to turn on, if it doesnt have a 12volt signal, it wont turn on, hence why when you connected it to the RED oem wire, it powers up.

this blue/yellow wire needs to have power . is there a fuse for this wire under the hood?

[Tommy]

From my haynes manual it looks like that is fused on the same fuse as the Dome light, not sure where that is, but check in the drivers side fuse compartment.

Here's a pic of what youll be looking at, its in the drivers side kick panel, under a black cover with FUSE written on it.

STEVETHECLERIC, YOU ARE MY HERO! i looked up dome light fuse in the manual and it turns out its under the hood and was 20amp and it was blown so i swapped it out with another 20amp.

hu boots up fine, along with everything else.... ALL RIGHT!!!!!!!!!!!!

[Tommy]

well, we can all do our part!

guess you can ignore that pic then, since it was the wrong thing, that one must come after the dome
