Connecting the A-B-A Units Together
Orient both engines so that the rear of the Lead Powered A unit (one with speaker
installed into the fuel tank) is facing the front of the B unit (the end with the wire
harness). The B Unit wire harness plugs into a receptacle under the A Unit’s rear
truck. When adding the Trailing A unit its wire harness plugs into the rear of the
B unit. The receptacle is polarized so that the harness can only fit one way.
DO NOT FORCE THE PLUG INTO THE RECEPTACLE.
