If i were to replace the MP OEM O2 with a Wideband O2 that has dual output (LC-1). How hard is it to route the cable to the LC1 through the same cable route as the OEM (leaving the oem cable intact but not connected at the 02) Can someone give a general description of the cable routing Ive not got a chance to go under the car yet to trace the route. How difficult is it to route new cable using the same route ? thanks
