Trace backwards from your fuel gauge’s brake light. This is the brake warning light switch that tells you when your brake circuits have been isolated because of a pressure differential (leak in one). I’m not certain where it plugs into your harness without looking, can do later tonight perhaps. Don’t be surprised if you have a brake warning light displayed persistently after fixing this- that’s usually why people cut them - and usually right before they sell them.
