23-Pin – $100 Advance Ship

If you have a 2014 – Silverado/Sierra 1500 Truck or 2015 – 2500/3500HD truck, and no longer have your jump seat harness (or don’t want to send in your jump seat harness), add this $100 add-on to your 23-pin conversion harness order.

With this, I will purchase the jump seat harness from GM and use that to complete your 23-pin conversion.

NOTE: DO NOT add this item to your cart WITHOUT the 23-Pin Conversion Harness!
