I highly doubt they write their own instructions, I also doubt they ever open the boxes. My guess is they buy the harnesses in various configurations in bulk, mark them up and sell them.

Have you made any progress on this? I am putting the parts together for my swap and really concidering one of these harnesses.

Installed mine over the weekend, laid down very well.



I wish there were a couple of extra feet for the ECM, but not a big deal. I'll mount it under the dash instead of the floor. The true test will be when I fire it up this month.

I wonder if they offer the "snake skin" wire covering for an extra cost?

They replied and said yes but there would be a T&M charge usd$50

.............. now I need to order the right one!!

[SBTork]

I'm trying to place an order for one of these, just curious how everyone that ordered one actually ordered it? I'm trying to go through paypal. If anyone has, did the company send you an invoice then you paid it or did you just send them the money via paypal?

I too have been looking into PSI harnesses. I was concerned to learn that they might be made in China...I fired the question off to the PSI sales department to ask if their harnesses were built in USA or made oversees. I will let you know what/if I hear back.

Thanks
Marc

Boy that was quick. I received the following response from PSI. It sounds like the Chinese company stole their instructions...

"Good morning Marc,

All PSI wiring harnesses are 100% made in the USA. All products feature GM Delphi Connectors and high temp TXL/GXL (cross-linked polyethylene) automotive grade wire. All connections are crimped per GM Specifications. Once built all harnesses are subjected to a pin-to-pin quality check and ship with full instruction manual. In addition to high quality products, we also offer over the phone technical support both before and after the point of sale. So if you have a question, someone is there to answer you in a timely manner, over the phone. I know there has been some imported knockoffs out there but these are in no way related to PSI or the products we sell.

If you don’t mind, can you tell me if the forum you are referring to is on Facebook or another site? Thanks in advance.

Also, here is an article Hot Rod magazine just wrote about us.

PSI is coming out with a "builders harness" soon that you can custom build yourself to your needs. Since my application will be somewhat custom, I may go this route (depending on the price).

Just food for thought when deciding on your harness.

Thanks for that Marc...!...makes me feel better about my psi harnesses...

[solidaxel]

Good answer!

They are Masters of reverse engineering!

No problem. I was in the same boat. Jon from PSI knows people steal their instructions thats why they took them off their site (as some people speculated). What was more surprising to learn is that the people selling the knock off PSI harnesses even provide PSI's tech line for trouble shooting....now that's bold.

Well we are waiting for some updates!

[mongocanfly]

My only complaint with psi was the ecm tail length...they wouldnt even make me a custom length when I asked...which I fully understand.....
they've been talking about the DIY kit Marc mentioned for yrs...but I havnt seen it for sale yet..
They are always quick to respond with any questions I've had....

[TooTall]

Just an update. I took a chance and ordered one. As I stated before, it came with the wrong injector pigtails, but they quickly sent over the correct pigtails.

Started playing with it and had a few issues that lead to a bad ground connection. Redid those, and it's been great ever since.

Delphi connectors are all over it.

Been driving it on the weekends with zero issues.

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

What did you do to solve this problem?

I'm not familiar with how long they promised a DYI harness. When I talked to them last week they stated that they have some harnesses on test vehicles to provide the kits and they said within the month they look to have pricing and timing..We shall see though.

The 2 large ground wires that had heat shrink were not crimped properly. Redid them and then it was all good after that.

My supplied directions that came with the harness look exactly like the PSI stuff. Even how the wires were zip tied and loomed together.

Other than that, zero issues. I ordered 4 more harnesses for my other projects.

[mongocanfly]

Marc I know it's been over 2yrs on the diy... I finally gave in and ordered the reg harness for the IH....then someone mentioned the bp harness has a longer tail than psi....had I known that ahead of time I would have tried bp....I still need a harness for my AD/LS3 truck...but I've got time to wait on it

DO All products feature GM Delphi Connectors and high temp TXL/GXL (cross-linked polyethylene) automotive grade wire. ??

[jjzepplin]

Subbed for info. I am super cheap so I am going to rework the original and pray. I do however suffer from the do it yourself five times before giving in and buying the right stuff syndrome.

It's nice wire, close to what painless is like

I've reworked the Gen3 DBC and DBW harnesses

This was too cheap and pretty to pass up
