Installing advancer emulator is very easy, as wiring harness comes along with the kit gets connected to its individual injectors very easily and through its own grips. Rest, two of the wires from advancer emulator specifically TL cuts the sensing line of MAF sensor and variable voltage is routed through the advancer emulator. One wire, see advancer emulator wiring diagram specifically connects with TPS sensing line. Change over switch provides the power to Monometer, Solenoid valves, Emulator and Advancer. Just combine the power supply lines blue and black with same wires from the devices. You are done.
Making connections is not difficult but art lies in not making a wiring mess inside the engine area.
