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:

Yea me too !

Re: New LS Standalone Harness
 

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.

Re: New LS Standalone Harness
 

Haha will do!

Re: New LS Standalone Harness
 

Any news on this?

Re: New LS Standalone Harness
 

It shipped on Saturday from Hong Kong via DHL. So once it arrives I will upload some pics.

Re: New LS Standalone Harness
 

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
 

Super fast reply, very knowledgeable and clearly understood my specs (i.e., 24x, DBW, EV6, etc.). Quoted me $180 plus shipping. Too good to be true? Maybe I’ll wait and see what the OP comes up with.

Re: New LS Standalone Harness
 

dang. for this price I might try them too. you have a link so I can see what they come up with for me?

Re: New LS Standalone Harness
 

Link is in first post.

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
 

That pic of your instruction sheet looks alot like the front of the PSI book....

Re: New LS Standalone Harness
 

yeah it does... I sent a request to the link on Friday, lets see if they msg back

Re: New LS Standalone Harness
 

Yeah all the add on part numbers start with PSI...I have not looked into that company, but this appears to be where they get their harnesses.

Re: New LS Standalone Harness
 

Any way you cab tell if they are using the proper wire type?

Re: New LS Standalone Harness
 

Connectors are all marked Delphi

I do not see any markings on the wires...so not sure about those.

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
 

So I am building a 54 3100 on an S10 frame and I will be mounting the ECM either under the dash or along the drivers side cowl panel. I have not measured the length of the harness, but it is longer than the stock. The fuse block will mount next to the ECM, wherever that ends up going.

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.

Re: New LS Standalone Harness
 

.
They were not marked in the original pictures

Re: New LS Standalone Harness
 

Just saw that - totally missed the original "received" photo. Thanks!

Re: New LS Standalone Harness
 

Subbed.

Re: New LS Standalone Harness
 

Yeah, I did that based off of the instructions. Figured it would make things a little easier.

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
 

This is a hell of a deal of this thing works!!! Has there been any progress?

Re: New LS Standalone Harness
 

No I am still building the entire truck. I am sending the ECM out this coming week to get flashed. I am thinking in about 1 month I will be wiring everything up

Re: New LS Standalone Harness
 

Do your ECM connectors and what not look the same? What is the writing on the heat shrink on your positive starter wires? Looking to see if anything matches. None of my wires have writing on them other than the 2 red starter wires.

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

Re: New LS Standalone Harness
 

One day I will build a hot rod using 100% American made parts. Until then, I will use what is available. Until I can afford $700 plus for a U.S assembled, probably made from foreign component harness, I will use this one.
