Abstract: A hand tool for engagement with a partially disassembled engine connecting rod with the tool having a handle-shaped base having a channel within which angular arm members are slidably and lockably mounted. Each arm member includes an extension defining a socket for reception of a connecting rod bolt. The sockets are off-center to provide variable spacing of the sockets upon rotational positioning of the extension on its supporting arm member. A modified base of the tool provides a concave surface against which an engine crankshaft may be biased to utilize the crankshaft in a piston and connecting rod removing operation. Arm members diverge slightly for purposes of providing inherent biased engagement with connecting rod bolts.

Abstract: A harness for installation on a coupled plug and socket with the harness including a primary ring-like member from which a pair of elongate connectors extend in perpendicular fashion. A second ring-like member is adjustably coupled to the elongate connectors to permit harness installation on a variety of plug-socket combinations. The ring-like members are also adjustable for like purposes. The harness may release the plug and socket under extraordinary forces.
