New LS Standalone Harness
Not sure if this was allowed, and I do not endorse nor work for these sellers, but I was looking on eBay for a 5.3 standalone harness or rework, and all of the new harnesses look exactly the same, and sell for $349 + or so. Figuring that they all came from China, I hoped on Alibaba and did a little searching and chatting. Turns out there is only one manufacture in China that makes this harness, and they sell to everyone that carries it. When I asked about pricing, she told me $268 shipped for 1, or if I order 10 or more, the price goes to $240. She did say that she can customize the harness to any spec I wanted, whether that was added or removing sensors or trans and lengthen/shorten the ECM leads. So I ordered one for $268, figuring I will save about $100 vs eBay. I will do a review on it when I receive it.
Anyways, here is a link if anyone is interested: https://www.alibaba.com/product-deta...52c38538gfq5ON |

Drive by CABLE only !

Re: New LS Standalone Harness
Its a blue/red harness so its set for the early stuff on 411 pcms. Thats probably why its got the "DBC only" note. Wiring and connector need to be modded to work on the blue/green (late 02+) ECM's but will lack DBW control. If your using a cable setup, then be aware that some of the later GenIII Ecm's lacked IAC control to to DBC.
I may also be missing it, but in the pics it appears there is only a single ISS on the harness, meaning its setup for a 4l60e. MFG doesn't show wire type either. TXL? GXL? Non rated? You have to be cautious with longevity of cheap wiring. Ask anyone who's bought an imported trailer lol. |
Re: New LS Standalone Harness
look at the other harnesses below . they have DBW stuff .

Re: New LS Standalone Harness
I ordered for an LM7 with drive by cable and a 4l60e. My old harness was so brittle that taking the chance on this is worth it to me. Worse case is I have to buy a new year or two.

Re: New LS Standalone Harness
Let us know how it looks when you get it. Its not that we don't want it to work; its that we've chased enough crazy wiring for a lifetime lol.

sounds good. ill be waiting!

Re: New LS Standalone Harness
I ordered a DBW harness from them and attempted to get it with the EV6 (08 and up)injector plugs.
It showed up with the wrong plugs, (99-06) and poor solder connections. They ended up sending me the correct pig tails, but the harness still does not work. I've started pulling off all of the loom to do some trouble shooting. You're better off modding an original if you want to be cheap |
Re: New LS Standalone Harness
So the guys who received said harness- I have a project in the works- 1989 K1500 with 24X LS conversion set up on SBC that has been waiting. I do have a 1999 truck harness or...pick this harness up. Or does anybody have a lead on a repin service?

Re: New LS Standalone Harness
I emailed them with my engine specs, interested to see what they come up with. They say most aftermarket sheet metal comes from only 1-2 places overseas so maybe the same holds true for aftermarket wiring harnesses?

Re: New LS Standalone Harness
So I got the harness in today, and I am happy with it so far. It will be about a month of so before I am ready to test the harness, but here are some pictures.

Re: New LS Standalone Harness
The instructions are better than what I have gotten in the past when sending my harness out to get modified. I will post some pictures of the instructions here soon.

Re: New LS Standalone Harness
Thanks for the update, looks clean. What is your take on connector quality? Keep us posted.

Re: New LS Standalone Harness

Re: New LS Standalone Harness

Re: New LS Standalone Harness
Based on what you see on the wire lengths, where would the ECM need to be mounted with this kit?

Re: New LS Standalone Harness
Did you have to label the wires or did they come labeled like that? Apologies if I missed it in the thread.

I planned on posting instructions yesterday, but I got called to travel for work. So I will scan them next week and upload them. One thing that was interesting is that on the PSI website, they offer instructions. But when you go to click on them, they have been removed due to "unauthorized" use. So it could mean one of two things. Either this harness is made for PSI, and the whole "we are the only ones who make the harness" thing is true, or this harness that I bought just stole the instructions from PSI. Does anyone have a PSI harness for an LM7 and maybe we can compare a few things? See which is which. |
Re: New LS Standalone Harness
ive got a PSI harness for mine..but mines for a manual transmission

Re: New LS Standalone Harness

Re: New LS Standalone Harness
Looks very much like my $650 harness that BP made for me. The quality on your chinese harness looks good. I hope it works awesome for you! From my experience the chinese quality can be decent but consistency is a challenge throughout most of asia. You could order 1 of these it works great- the next forum member gets one and it has all kinds of issues with it.
Throughout this latest build of mine, I ended up buying a few parts /items twice because of poor quality or bad choices on my part. I get angry at myself when this happens. The BP harness being $650 was a big chunk of cash to part with. After looking at all the work involved in building one of these, I can see where that $ price comes from especially with American labor. If yours chinese harness ends up having no issues than you just kept $400 in your pocket! The Chinese are masters at reverse engineering- I have seen them make some excellent quality copies of so many tools auto parts etc. The problem is not that they are not capable of producing great quality it's that the chinese begin to water down materials for their own financial profit margins. As long as the chinese contract source is sticking to their original build spects agreement- the quality can be fine. This is where many American companies whom partner with China become frustrated. The Chinese manufacturing middle men, or the shop actually building the product eventually start using cheaper wire, connectors , solder etc. so that they can make more $$$. They do this without informing the customer that places the large order. This exact situation happened to one of my family members. Unless you are Apple or another billion dollar company- this quality control is a challenge. My relative ended up abandoning the China mainland contract and went with a Taiwan factory. He did say that he then went with a Taiwan and had excellent results with quality control. Keep us posted - I am subscribing to hear the results!! I love it when myself and others on this forum are able to save money and not have to sacrifice quality!! |
Re: New LS Standalone Harness
Just American jobs
