Jeep codes are difficult to find. In the good old days, they hid them on top of the radiator support, under engine grease and oil. Later models put them on the drivers door jamb. Typical format: BS/GBS; only BS is the color code (also QBS, PBS, TBS, etc.). The first letter is a "Year Code". BS corresponds to Deep Water Blue Pearl Clearcoat; the G in GBS is not part of the color code. Lately, Jeep lists just BS.
