I wiring up new speakers and head unit in my '89 4Runner, and I've hit a snag.

The rear speakers I have have integrated LEDs, so I ran those wires back to the head along with the speaker wires. I soldered the two LED power and ground wires into one power and one ground, then I prepared to solder them to the power leads going to the head unit(I hear LEDs don't draw much power). I cut away some insulation along the head's wires, then I held the LED power and ground wires to the exposed contacts. The LEDs light, everything's good. I wrap the tips of the LED wires around the bare spots in the head wire and recheck the LEDs. Not lighting. I check the current coming off the head's power wire: 0.00 volts.

I'm going on the assumption that somehow the pliers I used to wrap the LED wires around the power wires caused the power and ground wires to make contact and short. I'm looking for the fuse that goes to the radio, but none of the fuses in my truck are labeled. I have no clue which fuse to check/replace. Does anyone know which fuse it is, or possible other causes for my head power suddenly going dead? Thanks!

 

i think its the 15amp acc fuse its at the drivers kick panel

Sorry that link, doesn't specify "radio" its the cigarette lighter one

 

Thanks for the link, but now I have a bigger problem: the fuse is not blown. I can't understand why the power wire should suddenly go dead like that. I need help!

 

Definitely not the case, I've checked and double checked the leads. Also, I measured the volts on the exposed power wire contact and it came out at 0.00v (yes, the truck was on). It's simply not getting power.
