if this is a factory fitted one its very difficult but it might be an after market so remove steering cowls and look for wiring coming out of rear of ign barrel,follow this until you see after market wiring added and taped up around original ign wires ,untape and look for 2 wires that have been cut so you ll have 4 ends with black wires soldiered to them ,cut the black wires and reconnect and match wire for wire by colour code ie blackwire with white trace to end of black wire with white trace ,only 4 ends 2 wires to join
