Cummins CM220 Standalone Harness


Yes I know this a little harsh. Sorry to get your hopes up.

We currently do not offer and have no plans to offer any CM2200 standalone harness. These ECUs are extremely temperamental, and in a stock truck have many explainable issues that can be severely power limiting and frustrating. Much less in a standalone setup. Since we do not have a huge staff of technical support specialists to spend hours on the phone trying to aid in diagnosing temperamental ECUs we do not plan on offering on. 

The best we do can is offer help getting you setup with either a CM849 harness, or CM2100.
