Hello Guys,

I'd like to introduce our NEW LS1 Engine Harnesses. Here's a sneak preview of what you can expect.

The quality is top notch and the best design and assembly we've seen.
That's one reason we decided to build these, to offer a cleaner, tighter fitting harness.
-Every harness is covered in high-temp heat shrink or high-temp wire loom.
-High-temp TXL automotive wire
-Every terminal is soldered-ensures connection will never fail!
-OEM weather tight connectors
-OEM wire coloring for easy identification
-Tested before we ship so there's no second guessing the harness
-Easy installation
-Easy hookup, one ground wire, one battery wire, one ignition wire
-OBDII diagnostic connector
-SES light
-Speedometer and tachometer signal
-Custom lengths (ie O2, maf, vss, pcm location)
-Weather tight fuel pump relay w/ 12g wire
-Labeled connectors
-Options available - custom length, configuration, electric fan control, pass-thru firewall connector (one of the first we've seen, allows you to mount the pcm in the cab by using a weather proof connector)

-Oxygen sensors available
-Custom programming available

This basic harness is $550 and fits any LS1 engine with a standard transmission. Add for automatic, integrated fan harness, and custom lengths.

We guarantee this is the best looking, tightest fitting harness available!!!!

Every harness is test fired before it's sent out, this ensures your harness is 100% trouble free.


thanks,

Allen

man that looks nice. good job allen :cheers:

Wow! Very clean looking! I like that alot, that harness really cleans the engine up, I really like the PCM in the cab deal, gives us a little more room in the engine bay:)

You'd do good posting this in the Conversions and Hybrids section on tech.

Looks awesome!

Got one that works with the Radix?

That is one sweet harness! Would love to see one for the new LS2 with relocated coils.

Any news on this for the LS2 yet?

Where do you put the pcm?

Does it include the coil pack harness?Im gone to need a harness in the next month.

We can make one for the Radix, it'll be very close to the truck harness. However, it won't be a direct factory replacement.

The pcm can be mounted anywhere in the engine bay, or some push the connectors through and have it in the cab under the dash.

The LS1 harness is almost done!

The harness doesn't include the coils, just the main connector.
thanks for considering us as your harness supplier.

Coming soon, alternator power wire, starter wire /relay and battery cables.


thanks,

allen

How hard would it be to adapt this to a GEN III-powered truck? I want to run a car intake setup on mine, but have never really figured out what to do with that huge mass of wires that comes up over the driver's side valve cover.

VERY interested in more info when it becomes available Allen. Looks killer!

:werd: I really want to get all that ugly crap off my engine so I can make it look a little better. Hopefully this will be the answer.

I am after the same thing. Allen is working on an engine harness for my SSR to get rid of the huge bunch of wires. This combined with the coil relocation will make it look like an engine.

A coil relocation kit for the trucks would be sweet too. Something to get them totally off the engine, maybe to the cowl up and behind the engine. That way we could run some pretty valve covers.

Check the thread I started in the show and shine section. I cannt wait for the harness now.

Not hard at all. You could run some of the harness you have now, and install something cleaner for the intake.
I'll keep you guys updated,

any updates on the harness's. I just got a 5.3L for my chevette :)

We're going full speed on the harnesses! We already have quite a few out there and they are working great!
Any additions I mentioned above can be added, just give me a call and we'll get your engine fired up!

thanks,
