Caterpillar 235-8202 Aftermarket Engine Wiring Harness

Caterpillar 235-8202 is the C9 engine wiring harness in braided sleeving, with the engine control module plug and the sensor connectors. It is used on Caterpillar C9 engines. This aftermarket version has the same mounting and electrical connector as the original, so it plugs in and bolts on where the old one came off.

Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Technical properties & sizes

Applications & use cases

Intermittent faults and warning codes
Chafed, crushed or corroded wires in an engine or main harness give faults that come and go: sensor codes, a rough running engine or a machine that will not start. When several sensors fault at once, look at the harness.

Heat and rodent damage
Harnesses next to the exhaust and turbo go brittle and crack, and rodents chew the insulation on machines that stand. A new harness is quicker than repairing many wires.

Burnt or corroded plugs
Green corrosion or melted pins in the plugs cause high resistance and false readings. Replacing the harness renews every plug at once.

Fitting tips
Disconnect the batteries first, photograph or label every plug before removing the old harness, route the new one along the same clips and away from hot and moving parts, then clear the fault codes and test.
