Yes the Jeep is set-up chassis as ground, not the positive.
If you plan on using a 12VDC power adapter plug for your CB, make sure that you connect the positive wire to the center pole on the power plug! The outer prongs are the negative. Keep a fuse inline! Most power plugs have an internal fuse.
PM me and I will send you a power plug. Shoot me a picture of the wires and the back of the CB and let me know what brand and model it is.
