Connecting the A-B-A Units Together

Orient both engines so that the rear of the Lead Powered A unit 
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.
