I got my (dead) grandpa's old CB radio. I'm wanting to install it into my 89 toyota pickup. I looked under the dash/cigarette lighter/ash tray area and found a bundle of wires. Red, black, yellow, green...which two are powered that I can split off to power the CB radio? Do I need to go in with a multimeter or can someone point out the right colored ones?

 

well red mostly hot yellow is mostly switched black is mostly ground and green sounds like a light id say try that WITH a tester to make sure as i dont know what wires your talking about just test them and see what does what and when

 

pff. It never occured to me to even wire it directly into the fuse box. Could I wire it to some 30 amp fuses under the dash? The previous owner has the fog lights wired this way, with a switch under the dash to enable/disable them. Could I do the CB the same way?

 

You can, but the radio should already have a inline-fuse but if not add one I would do 15amp though maybe even 10 CBs dont create that much amperage, In the chevy I just wired it directly to an unused spot in the fuse box, works great and turns off when key is removed!!!
