What’s the difference between the 2189 and 9123 GM LS tach adapters? Thanks Thank you for the question. The 2189 wire harness plugs into the 9117 signal adapter. If you need to buy both the wire harness and the signal adapter, 9123 is a package including both the 2189 wiring harness and the 9117 signal adapter.Date published: 2018-09-12
