HPI 97-06 LS1 STANDALONE Wire Harness 4.8 5.3 6.0 VORTEC w/60A Relay (Drive by Cable) (RED/Blue PCM) & EV1 Fuel Injector CONNECTORS for Harness Swap (4L60E Drive by Cable)

Bought this for my 87 c10. Harness was made very well. Everything clips right up. Used existing hole on my firewall like it was made for it. Had an issue with me having wrong o2 sensors and a battery draw. Seller was quick on solving the issues and I felt dumb not reading the instructions that clearly had my answers afterwards lol overall very happy with it and will use it on future swaps.

Very good quality and worked good on the car

10 grounds are stripped back 3/8” and crimped into a ring. They pulledOut and all black taped up, so no easy troubleshooting. Colors are wrong and directions are a copy of a copy of a bad copy done in 1892.I asked about the pink wire and the response was “its not used” its a stand alone harness built by them, so why is it there? I wanted to know whats the pink wire, not a move along answer. I fried 2 pcms, im not a newby... its alllllll black taped up, so zero troubleshooting or inspecting.I build multiple trucks at tye same time, so I dont always get to the products quickly. I then opened tye other harness I ordered (blue red gen3 dbc) and it was a blue green.Was past the time to return. I opened it up a bit and found wires slighly loose again in the wringlets.I have a odd feeling these are made across the ocean. Cant verify, but zero qualityTore all out and ordered a Terminator X max.Thanks A hole, you own me.

Have been using these for swaps they work well i have gotten some issues before with maybe 3 harnesess out of 120 that i have ordered and used but nothing that simple wiring diagram cant help with. I do recommend for your ls swap.

I bought this harness going in knowing it wasn’t going to be the best of the best, it’s a great value for the price and everything works as it should. One thing I would recommend would be a better quality loom, and more tape other then that it’s been great!

This harness met my expectations and even exceeded them. HPI produce a tremendous product. Every connector is professionally installed and connected flawlessly for my application. I didn’t have any problems routing the harness or with any of the connectors.I’m sure if you’re like me and wanted to take the time to make your own harness figuring you could save some money. After receiving this harness and being able to toss the old bulky truck plugs, fuses, and excess I highly recommend saving the exhaustive amount of time it will take to reproduce a hacked up harness and buy something new.The harness came with everything needed to install and some very useful diagrams and referencing to connect with my application. HPI is quick with a response if you have any questions about shipping or need anything. Great team and a tremendous product.

This harness was exactly as described. This was my second Amazon harness so I was skeptical because the first company's was trash. Pinned wrong missing connections. This harness was perfect, and I needed some adapters for my injectors they shipped them out first thing. Best communication and harness at a fraction of the cost. Highly recommend.

The technical support sucks and they refer you to someone that's tell you that he doesn't know anything about the wiring harness. Pull on the transmission plug and all the wires came out. I have been trying to get someone on the phone for two weeks that actual know about the harness to help me put the wires back in the correct place but give me a third party guy that don't know nothing not even how to get in contact with someone at HPI.DONT BUY
