Im working on my sons 1990 Toyota 4runner. On your car stereo wiring schematic, it shows an “n/a” for the antenna trigger wire color. This vehicle has a stock electric antenna. Im installing an aftermarket head unit. What wire do I hook the head units antenna trigger wire to so the electric antenna goes up. anyone?
Adam, it sounds like you blew out a fuse or two. It is possible for your radio to eject or load a CD but not turn on. This is because these functions are powered by different wires (constant wire and switched wire). Double check ALL your fuses and you’ll probably find a blown fuse somewhere. Sometimes when you short out your radio fuse, other fuses may also blow out. Hope this helps. Good luck.
hi, ive installed a DVD player into my 90 4runner all wires a correct as ive transfered all wires 1 by 1 from the previous stereo. but there is no power going to the unit ive installed alot of systems but this has got me stuffed on y its doing this… ive checked all fuses amd still noting… any help would be great
Kiran, your 1990 Toyota 4Runner may have a factory amplifier that needs to be turned on by your after market radio. The car stereo amplifier trigger wire has to be wired up to turn on your factory amplifier. Unfortunately, we don’t have this information but maybe someone from the Modified Life community can post that information here. Hope this helps. Good luck.
Hi, thanks for providing this information. I was given a working Panasonic MP3 CD Player/Receiver taken out of an old Mercedes. My mechanic tried to install it in my 1990 Toyota Camry Wagon and although there is power to the unit and the face plate lights up with all the standard digital inidcators, no sound comes out. The car speakers are fine, as I could play audio cassette tapes in it beforehand. Any suggestions? Thanks for your help. Kiran
