If your battery is under you rear seat, Check all the connections to the battery and fuse box.

All conections are clean. Battery has 12.7 volts and traced the power wire of the battery all the way up front under the carpet and have 12.7 volts up front at the fuse box. All Maxi fuses have power.. When I hook up the positive back on the battery, the horn blows none stop and headlights are on and stay on.. Grounds are all clean. Pulled ECM/PCM and all pins look good and connectors.. ??
