RDretired Posted November 17, 2020 Posted November 17, 2020 I am installing a deck on a 2020 3500 HD using the existing tail light wiring harness and installing some different LED tail lights. Everything physically works except that I get the rapid flash and dash pop up saying the signal / stop circuit is not working. I am using 2 LED lights each drawing 198ma for a total load of 348 ma. I have tried the 6ohm load resister with little change. Can any one tell me what the circuit load should be, or how the are getting that dash warning to disappear Quote
