For most models when you go to pick out your harness, you will be able to add an ECU, O2 Sensor, or an Ignitor. Each field has their own options so that if you’d like to purchase extra compatible options, you will have the ability to!
This harness will plug right in place of the stock ECU and instantly connect up to the MaxxECU Sport for all engine functions. 2 Twelve pin connectors on the harness allow quick and easy access to all available inputs and outputs for air shifters, nitrous, boost control, pressure sensors, temperature sensors etc. This is the easiest way to get started with a stand alone ECU! One box will do it all!
