It is a 500 foreman (not a rubicon). We installed a warn winch going by the directions now the 4wd does not light up or blink and it does not go into 4wd. To install the winch; We first tested the orange wire to find out not enough current for a winch. So we wired into the diagnostic port and pullback relay- which honda mechanic at first said that was the problem. But now it’s not. They have checked everything down to the ECM with no luck, then they put in a new ecm out of a Rubicon and did not fix it. So today the dealership suggested we replace the entire wiring harness. They said none of this is covered under warranty yet they can’t explain what’s wrong or why it happened. I need help, shadetree has also been trying to help. Any ideas????
