I installed my PSI harness today. The quality is better than OE! So simple to install; super nice harness.

I'm in a similar situation, I have a 5.3L out of an 04' Avalanche, and will be mating it to an 01' 4L80E. I'll be converting the injectors over to 80lb Deka's, LS6 intake and adding a 76mm turbo. I have the stock harness, but would be interested in a complete harness that would hook everything up.

I have dealt with steve and been dicked around with twice. I would not go back to Sand and Street Performance Wireing (SSP) again ever. Guy has lost my business. The harness above is a TON nicer than the ones we got from SSP. That PSI harness looks NICE!

RD,

We do not support the E40 ECM as it was only used for 2 years. For our E40 customers, we can provide a harness that uses a 411 RED/BLUE pcm with a tac module and pedal. We can set it up for the 4L80E transmission as well. Please PM or give us a call at 732-691-6531 to discuss specifics.

Jon, do you guys offer a covering other than the plastic loom pictured above? Some of your competitors are using other materials that are more pleasing to the eye, just wondering if you had an upgraded option.

Hey Jon, I am also interested in buying a harness from PSI but the only thing that is keeping me from doing so is the split loom. Is there any other covering that is offered from PSI? Thanks

We do not currently offer any other covering, but if there is enough demand we would consider it. The intent of the split loom is to look factory. The braided snakeskin type looks cool, but traps dirt and grease. The heat shrink harnesses wouldn't be my first choice.

What other covering did you guys have in mind?

We have done a few harnesses without any loom, for custom builds as well.

These harnesses look nice but if you havent seen the chasebays engine harnesses then check them out. They are made to your specs and can be made for any chassis wether it is a older 70's swapped chassis, a race chassis, or a modern g35 sedan they can make it.

Here is a picture of their LS2 CM1 engine harness





Here is a picture of their LS1 CM2 style that comes with a military grade cannon plug for quick disconnecting at the firewall. No fishing a engine harness through the fire wall when you dont have to.



Here are is a picture of their full mil spec harness with Raychem DR25 high heat and diesle fuel resistant heat shrink and individual sensor labeling.

Fatfreegto - Their nylon loom is low quality its not going to be a tight woven loom. You can pretty much see through the waytek loom when it is used on a engine harness.

The link I posted is for a split nylon loom which will come in handy for someone who is simply trying to replace corrugated plastic loom or cover existing exposed wires. They do offer other expandable type loom which is a thicker material.

As for needing a business license, tax ID, and a buy in to place an order from them that is not true.

600 bucks for a harness with no fuse block or fuel pump relay....and I didn't see a provision for the 13 pin auto trans connector.........nice stuff, but I don't think so....

Convoluted tubing or not, looks to me like PSi is the better value for the dollar...

I did not need a tax ID or license and have bought a ton of stuff from Waytek. Maybe it changed though.

Del City is another source for that stocks most of the same stuff as Waytek.

Chasebay, yep, thats the one I had in mind. Thanks Dan.

TomM, I'm with you here:

About $100 bucks less and PSI's is pretty much plug & play, can't beat that!

T,
If look on their site you choose the chassis that you are putting the harness into. If it does not use the existing fuel pump relay on the chassis then one will be added into the harness.

If you also look at the options they have options for the 4l60e but can do any other automatic trans as well.

Here are the options that have drop down menus that you choose according to your setup.

What Chassis?:
What Injectors?:
What Motor?:
What Transmission?:
Which ECM/ECU will you be using?:
Which Harness Model?:
