If you’re tuning a Ford diesel, this harness kit from Mrsovax makes it easy. It’s a plug-n-play electrical harness that fits 2017-2020 Super Duty trucks with the 6.7L Powerstroke—F-250, F-350, F-450. Also fits the 2018-2020 F-150 with the 3.0L engine. It’s made from high-quality ABS plastic, so it’s tough. Just plug it in and you’re ready to connect your tuner. Comes with a 1-year warranty. If you’re messing with Shibby Engineering stuff or just need a clean harness, this is it.
