Ok, im installing a head unit in my 1993. I lengthened the Metra harness so that it reaches. Before i do anything, i make sure that all the connections are perfect. I soldered and shrink tubed all parts. Its perfect. I plug it in to the harness behind the dash to test it. Works perfect.

Ok, here's the weird part. I go to install the head unit in the dash. Pull the old factory radio out. Get the Cobra radio fitted and the new head unit in the dash. Turn the ignition on, now i have no radio, no clock, no dome lights and no keyless entry. WTF?!!??!?!?! But it was just working perfect?!??!?!

I checked my fuses and didn't notice one fried...

Is it part of the anti-theft system??????

I put my stock radio back in thinking the new head unit was bad or something. Still no clock, no radio, no dome and no keyless entry.

Windows roll up, cigarette lighter works, antenna buttons work, defrost works, rear seat heat works, locker buttons work, etc.

What could have happened. :confused:
 
Double check all your fusing....I'd start there....

ALSO.....Your radio and CB need to be grounded to the factory brackets your factory radio was mounted too. In most cases the Metra Harness has a ground wire in it even though it doesnt connect to anything.

Most likely you blew a fuse somehwere....

If I was home, I'd jump on the 241 Toll Road and head over to fix it for you......Unfortunately my wife talked me into moving to her home town and I'm 2000+ miles away in Alabama....

Yep, Grew up in Palos Verdes...moved away for college.....returned to South Orange County. My parents live in Coto off the 241. My wife and I lived off Crown Valley Parkway & the 5 in Laguna Niguel.

We moved to Alabama 3 years ago when our daugther was about to start kindergarden. It sucks here....but you can buy TONS of house here for literally pennies on the dollar...lol....not to mention I return to So Cal all the time to visit and see friends....

Let me know if you get it working....or if we need to step up the Tech Support....lol
 
I second what was said above, connect the radio harness ground wire directly to a ground point on the dash sheetmetal or radio bracket. I've seen this happen on several Toyotas when using the adapter harnesses. Also you should find a blown fuse causing your other issue.
 
The fuse you are looking for is in the Engine Bay. I think its called Dome and its 15A.

I had this same exact problem! You'll want to remove the blue wire from the radio harness you purchased. It is supposed to be for the power antenna, and if it is like mine, it loops to another pin. We don't need that for our LC power antenna since it operates off of a switch. Instead, that blue wire and the loop create a short circuit with the factory wiring and blowns the fuse under the hood, which provides power to alot of stuff.

You shouldn't have to run any other wires. Just remove both pins from the metro harness so they don't connect to the LC's factory wiring.
 
Ill check the fuse under the hood. So far i've only checked the dash fuses that are in the driver area. That would make sense why i didn't find a blown fuse yet.

As far wiring the antenna, i didnt change the Metra harness at all because it worked. Did it blow the fuse when i started pushing the antenna dash buttons? I will remove the blue antenna auto wire now.

Thanks for all the help guys, i really do appreciate it.
 
Along the same Install... has anyone had troubles not being able to fit the Cobra radio and a regular head unit back in the factory hole? For some reason i cant get them to push back far enough on the left side. I've tried move the bracket too. Any ideas?

Everything is tucked down away from the two units. Appears to be plenty of room back there. I was thinking it was the cb coax sticking out too far out the back of the radio?

Dave - ditto landtank's 90 elbow on the CB. Everyone I'm aware of that's done what you are doing has put the elbow on the CB coax connection. Had an Eclipse installed Friday afternoon, but just had them put the storage pocket below the head unit. Little Uniden I've got is fine for now.
 
From Cruiser Dan in another thread: "Check the "DOME" fuse in the panel under the hood (between the battery and the ABS actuator). It is 10 amps and is in the rearmost outer corner of the box."

I didn't use a metra harness. However, the power-antenna wire that I cut was in fact blue on my wiring harness. My symptoms were the same as yours - I blew the clock/radio/dome light fuse every time I powered up the new stereo until I cut the wire.
