Connect bypass harness to wiring in the vehicle, Start the engine with the key. With the engine still running, remove the harness from the bypass and measure the resistance between the GREEN and BLUE wires. Next, write down the resistance and switch the leads on you meter and measure the resistance again. Write down this resistance and add the two resistance readings. Divide the new resistance value by two and use this average of the resistance values to set the dipswitches on the bypass module.

Take the WHITE wire from the bypass module and put it to a ground, The bypass unit will click. With the WHITE wire grounded, try to start the vehicle with the key. If the vehicle starts and remains running the bypass unit is set correctly. Return the WHITE wire to the WHITE wire in the 3-pin connector (WHITE ignition negative wire on the 16-pin connector(RS1100, 1200 and 1300 only).
