Outstanding product
I spent a lot of time looking for the harness I wanted. 5.3ls DBC with a 4L80E transmission and a 5 pin MAF. This harness fit my description except for the MAF connection, it was advertised as a 3 pin MAF. It had a 5 pin MAF. I installed it with absolutely no issues at all. I would utilize this harness again and I have nothing but good things to say about it. My swap fired right up, and I haven't had any issues at all with it. Highly recommend.

So worth it for the money
I’ve done few engine swaps so far, the last one I used a PSI harness and while this is not as nice it’s also a lot cheaper. I did have one pin on my injector that wasn’t completely in, but otherwise this is a great value for the money and I will definitely be purchasing one of these for any of my other swaps

Well made
After buying a few and returning them due to being so badly made I’m happy with this one ! Actually has a little cover for the fuse box and is a big longer so it reaches comfortable! Def happy with this harness

Works great!
I used this standalone engine wiring harness for my LS swap with a 5.3 and 4L80E transmission, and it worked great. The harness was truly plug-and-play, and the connectors fit perfectly without needing any modifications. The wiring feels solid and well protected, and the extra length made mounting the PCM under the dash much easier. Installation was straightforward thanks to the included instructions. After installing it, everything ran smoothly and reliably. Overall, a very dependable harness that made the swap process much simpler.

Good starting point for LS swap setups
Harness is laid out clean and labeled well enough to work through without guessing everything. Works for DBC setups with 4L80E which narrows things down nicely. Connections fit properly and routing is manageable. Expect to spend some time cleaning up the install like any swap harness. Solid base if you’re putting together an LS setup.
