ok guys, i posted this question in the 2004+ forum but im not getting anything. i am installing my CB radio and i need to find a good switched 12V source. i was hoping that there was one running on the drivers side rocker panel. ManualF150 said that CB's need about 4 amps of current. as for that i am pretty much lost. so where is the best switched 12V source that i can tap into to power my CB?

Id go in the main harness for it.... Wouldnt be hard if you can work a soldering gun...

i can work a soldering gun pretty easily. i just need to know what wire im going into. im not sure about the amperage or anything like that. would i need to throw a relay in for 4 amps? thats one thing that i dont know about is relays.

I dont remember the wire color. Grab a DMM and test.

B+ = 12v+ regardless of key position
Ign+ = 12v+ in run and start **** This will work****
Acc+ = 12v+ in run and Acc ONLY ****This will also work****

No relays needed. I guess if you wanted you could run one but it would be wayy too much work.
