The B expansion harness plugs into the FT550's B connector and works alongside the 4 Cylinder Universal A Harness. It adds four more injector outputs for up to eight injectors staged sequentially, a direct GearController sensor connection, CAN B and extra inputs and outputs. Buy it alone if you already have the A harness, or as an A and B set.
FT550 ECU only. The B harness must be used together with the FT450/550 4 Cylinder Universal A Harness.
Extra inputs suit driveshaft RPM, transbrake button, suspension travel, input shaft RPM or a staging button. Extra outputs suit boost control solenoids, transbrake solenoid, dump and lockup valves, gear shift and nitrous stages.
