WIRE CODE IDENTIFICATION Each wire shown in the diagrams contains a code (Fig. 3) which identifies the main circuit, part of the main circuit, gauge of wire, and color. The color is shown as a two letter code which can be identified by referring to the Wire Color Code Chart (Fig. 4). If the wire has a tracer and it is a standard color an aster-isk will follow the main wire color. If the tracer..

Apparently pin 4 (at the cluster) is 12v, pin 3 is ground. I found ground continuity, but no.. 4. Cut wire/ Solder resistor in-between ( for series ) I have a 94 YJ, some older YJ's will have a different cluster, but if you know which wire is for the fuel gauge it's the same procedure Here is my wire on my 94, the color was dark blue, and I believe the older style clusters use a tan wire, but referred to a wiring diagram to make sure.
