Don’t waste your time. Does not come with oil pressure switch plug.Sad part is my time to return item has pass. Shop just got to my auto.

We love this product so easy to install.

Thank you

The directions it comes with doesn’t tell you what the Underdash wiring goes to. Kinda disappointing

When it comes to LS swaps, finding a reliable and affordable wiring harness can be a daunting task. Enter the 4L60E Engine Wiring Harness, a standalone wire compatible with 1997-2006 GM DBC LS1 4.8L 5.3L 6.0L Vortec Engines paired with a 4L60E Transmission. This harness is a game-changer for budget builders.To put things in perspective, if you wreck your car and wipe out the harness, a new GM harness will set you back $600. They don’t charge $550 in markup. This harness, however, is a steal at $82. For that price, it’s reasonably good. If you want something plug-and-play and don’t want to fish it out of a mangled wreck at the salvage yard, this will get you going.Be especially careful when plugging things in to avoid bending any pins. This can happen with factory harnesses, sensors, and computers too. It’s new budget wire in budget connectors but has what you need to get a DBC 5.3 running with a 4L60E junkyard trans. It’s a good value part for a budget build.

MISWIRED CONNECTORS AND NO CUSTOMER SUPPORT

The wiring harness is fully assembled and will function independently; simply connect an ECM. Although it's not a "high" quality harness, as the wires appear to be PVC insulated and the connectors don't match OEM standards, it's an excellent product for the price.
