Does anybody know the wiring sequance for using a cel fix on a my02 car.I have a friend who recently purchased a Scoobysport exhaust via e-bay.Included was the cel fix but no wiring diagram.We have had a local garage e-mail Scoobysport but have recieved no reply.The unit we have has 4 wires,orange,blue,black and yellow.
Thanx.

 

Si,
Cut the blue/silver wire to block135,pin 17.connect the orange wire to the ecu side and the blue wire to the side that goes to your 02 sensor,solder all the connections and insulate them.Carefully remove some of the insulation from the yellow/blue wire to block137,pin 3.solder the yellow wire onto the yellow/blue wire insulate the joint.earth the black wire to the chassis using the ecu locating stud and nut.
Looking at the ecu block 137 is at the top.
block 135 is second from the bottom.
sorted.
