MPS Lectron Throttle Position SensorThe MPS Throttle Position Sensor was designed to work with a 4 to 1 throttle cable for 4 individual throttle bodies or carburetors. It uses your existing Lectron throttle cable. Just remove all cables from the original round 4 1 junction block and install in the new TPS junction. The 2 long cables go to the outside and the 2 short cables go to the inside. The cable from the throttle to the junction goes on the top in the single hole. Electrical
