4L60E Engine Wiring Harness Standalone for 1997-2006 GM DBC LS1 Vortec Engines 4.8L 5.3L 6.0L, Add 8 x EV1 to Delphi, W/4L60E Transmission Drive by Cable

Be aware that the picture identifying all the plugs is wrong. Specifically the fuel injector connectors. Each row is 2 4 6 8 and 1 3 5 7...Don't go woth their labels. Verified with a meter.

I got this harness wanting something cheap, but I was willing to fix it if I had too. Sure enough the ground for the MAF was not stripped before the end was put on. All and all good harness for the price just be willing to either fix issues after install or get a good pin out and go through it before hand.

Highly recommended if you need a standalone harness for an LS swap

The other reviews were not kidding when they said to check your pin outs. I found 5 wires in the wrong pin positions. The connections fittings are not correct and need to be changed. Nothing is easy or correct with this harness.

Shipping was fast .product is good .there are no instructions. None of the wires or connectors are labeled. Had the wrong fuel injector plugs were wrong for my engine .but I fixed that .if the wires were labeled or there were instructions I would give 5 stars but that's something that really should be included in a $150 wiring harness

The media could not be loaded. It’s a good harness wish it had wires labeled and also it’s missing the oil pressure sensor overall my swap is running great

Injector connections did not match

The relays that come in the harness #1 is for the fan,#2 for 12v ignition relay, it does not have a fuel pump ground signal from the c1 blue plug you'll have to add a pin on #9 and a relay/ does not have a 12v constant from the battery/ ignition source both tied up at starter. Wiring directions are a little sketchy, doesn't show any Wiring diagram. The quality is good really nice loomed and wired.not really a "plug and play" harness wouldn't recommend it for someone that's new to the ls swap scene.
