Shibby Engineering Tuner Harness Plug Kit, 2017-2023 GM 6.6L Duramax, L5P

L5P Tune Plugs

While tuning my 2017 L5P I noticed that I was going to have numerous open ended connectors. Looked online and found this kit. To be honest I thought about using ZZDiesel first but went with another seller because of a small difference in price. I needed up cancelling that order because of stock issues and came back to ZZDiesel. I reached out about their stock and got a response within 12 hours. I made my order and had product in hand within 3-4 days. Excellent product sold by an excellent company. Thank you ZZDiesel!!
