I've got a wiring harness that I am going to use as a replacement for what's in the truck now. My truck has the gray remote mounted TFI module and the harness I got has the black remote mounted module.

I see there's only a small amount of wiring between the two but I'm not sure if I should change it. Is there an advantage to using one vs the other? If not I'll just keep the black one on the new harness

Thanks
