I know this has been discussed hundreds of times, but I'm looking for an easy way to allow my lockers to engage in 4-Hi. I recall that, several years ago, Superchips offered a unit that included this feature. That would be the easiest approach, but I don't think it's available. If anyone's tried the re-wiring suggestions on a 2015, can you post back with the link? I just want the ability to use the lockers in 4-Hi and prefer to use the stock switch. Thanks.
