Proper elec hook up for radio - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Murphy IRE · 04-23-2010, 10:22 AM

OK while I have the dash out, I want to fix the radio. It's an after market Pioneer Cd/radio. The PO wired the radio on a hot only circuit. I want to tie in on the ACC mode and have it work when the truck is running.
Thanks in advance for the help.

Sounds like a simple job. It's should take 3 wires; ign, acc, and ground.

Just hook the main power lead to the radio terminal on the fuseblock. Leave the memory lead connected to the always hot lead or else your radio will forget things.

There are still flags on the wiring for the radio.
The Red wire which has the in line fuse says ACC. Should this be pigtailed into an ign hot wire?
The yellow wire says battery. So I'll splice the yelllow line into a hot wire.

OK I got the wires figured out. Yellow to always hot and red to IGN connector. I checked and I have power into the the back of the radio all the time with the yellow. The IGN wire has power when turned on. The wires are hooked up correctly, according to the instructions. BOTH fuses are still good, but nothing happens. The ground is good.
CONFUSED.

Does the head unit itself have a fuse under the wire harness? And i mean under it like disconnect harness from head unit. Or anywhere else thats not in a wire line? If so it may have popped during all your trial and errors. Or in case you havent check you might have blown a fuse in the fuse box when you werent looking. If thats not the problem does the unit work when you just go hot all the time?

It's good and so is the in-line!

jcsbrat · 04-30-2010, 01:11 PM

And does it work when just red and yellow are together running "hot" all the time?
Do you have the ACC wire hooked up to the "radio" space in fuse box? If so, is tester lighting up when touching spade? On the bottom three fuses if fuse box is vertical the 1st and 3rd fuse should work when key is in all three positions (ACC/Start/On) if temp plug there you will maybe can start eliminating.

Did you get this taken care of? If not i can try and post a pic of where my wires are connected at in fuse box.

Murphy IRE · 05-03-2010, 05:45 PM

I haven't gotten to the radio, I've been fighting bigger battles on the heat/AC system. A diagram would be great!!!.
Thanks alot

Actually I found what id tell you in another members thread. the tread is PROJECT BLANK SLATE in PROJECTS AND BUILDS. its about 1/4 of the way down his first page. If that still dont help give me a hollar.

Murphy IRE · 05-03-2010, 11:04 PM

Found it. I think that's what I eventually did, but I'll check it tomorrow. I did something else at first and I'm hoping that I didn't cook it! I'll double check the red wire connections on the in-line fuse holder. It wouldn't be the first time one of those came lose.
Thanks,

Murphy IRE · 05-04-2010, 08:12 PM

Don't Know what I did, but the new Kenwood works great.
Thanks for all the help and suggestions!
