my jeep gives me all kinds of problems with wires and grounds.. i checked everything and put a ground from the battery to the body yay were fixed.. until i started installing a radio, someone had cut the harness out so i started wireing it directly with a list of the wires i.e pink- 12v constant black- ground etc. but still isnt working right so im thinking theres problems with the radio circuts.. now my question is.. is there any guides or anything on here about rewireing everything from where the wire starts till it meets the radio like i want to run a wire constant stright from the battery to the radio and the ground to where i know its grounded etc. and the speaker wires i know they them thats the easy stuff but just info on the constant and the ignation and dimmer, etc. any help is greatly appericated thank you - mark
