If the connector that is plugged into the ECM motor does not fit on the QwikSwap® board, you are using the wrong QwikSwap®.
Constant Torque ECMs are also sometimes referred to as X-13 motors and have a 4-pin connector and 5 individual speed/torque taps, which will only plug into a QwikSwap® X1 or QwikSwap® X3. The X1 will then drive a PSC motor at a single speed, while the X3 will drive the PSC motor at 3 speeds by activating different speed taps on the replacement PSC motor.
Variable Air Flow ECMs are also identified by their unique connectors. All Variable Air Flow ECMs have the same 5-pin power connector and either a 4-pin or 16-pin digital communication connector. These connectors will only plug into a QwikSwap® V3 board.
NEVER cut the connector off the wires to make it fit. This will NEVER work.
