How to replace the underhood fuse box on Cadillac CTS?

The foremost task for changing the underhood electrical center or junction block involves disconnecting the battery according to battery disconnect safety rules. To start the replacement, first unfasten the negative cable fastener from the Fuse Box and then remove both the electrical cover plate and fastener. Use a tool to detach the electrical connector and loose the fasteners which maintain the Fuse Box board in position. Unlock the Fuse Box by opening its tabs and lift it up before pulling on the harness at its locking tabs for removal. Unfasten the two securing elements (1, 2) that hold the Fuse Box to its vehicle mounting position. Fasteners (1, 2) should be used to install the Fuse Box on the vehicle body with a torque of 10 n.m (86 lb in). The harness should be placed into locking tabs before you fasten the Fuse Box board into position. After returning the negative cable fastener to its correct position on the Fuse Box proceed with placing the Fuse Box cover in its position before installed the negative battery cable.
