I need to know whiCh are the power and ground wires coming out from a 2011 cobra 29lxI dont have the output plug so i want to solder my own power pluds to come out of the radio

Open the radio up. Follow the wires from the plug and one will terminate to ground. Most likely on a board, where you may have to trace that wire to the chassis, which is ground. Most likely, they are color coded. Black is ground, red is power.

Ground wire location

You can connect the ground wire to any part of the chassis.

As for the orange/illumination wire... depends on the year of your truck and the make/model of the new radio. Re-check the installation instructions - it should tell you where to connect it.

Radio and inside lights not working

Check your grounding, prob have used illumination line as ground, when lights switched on it goes to 12 volts and if connected to radio ground fuse will pop. Ground radio to chassis and isolate the wire you have used, replace fuse (probably blown) and should fix your problem.

Jeep radio w/cd player

begin with the easy one. code is for battery disconnect.(if you had the battery disconnected while installing that will explain it) if you ground the antenna wire to the chassis does it still spark? Is it a power antenna? I'd make sure that somehow the clock and radio wiring is not reversed and that the radio is well grounded (you can add a ground from the case to the main dash rail if you need to. As with any used item, there is a possibility also that there is just something wrong with the radio, but I don't think that yet!

What is source ground on an equalizer

Ground Source, not the other way around. It is a metallic place, interconnected to the vehicle chassis, where the electricity will flow from positive to negative. Best bet is to connect your equalizer black ground wire to the radio black ground wire, since it has already been bolted to a good ground. Furthermore, grounding it to radio, will prevent any humming between the two units.

What type of car is it? Make sure the Black (Ground) lead for the radio is connected to an adequate ground wire in the harness or to chassis metal. Some vehicles (Nissan, Mitsubishi) have no ground lead in their harnesses and need to be grounded to bare metal.

Most standard CB microphones are 4 wires:
Audio IN (from Mic)


To determine which is which on the radio side:
a. the Audio IN (from Mic) would read a high resistance to ground (chassis) of CB radio;
b. the Speaker when connected to the ground would activate the receive speaker. To verify, power up the radio, squelch all the way down, when shorted to ground, speaker will produce background noise/sound;
c. when PTT (TX) is shorted to the ground, the rig will transmit and the red TX indicator will light up;
d. Ground. when tested with an Ohmmeter to the chassis will read 0 ohms.

Hope this be of some help/idea. Pls post back how things turn up or should you need additional information.

Good luck and kind regards.
