This is "Test Row" where all of your harnesses are run on a real live engine before delivery. We do this with ALL harnesses whether we are doing a stand alone factory rework, or building you a brand new custom harness.

Here's a 2002 LS1 complete package we recently finished and delivered. This is going into a high dollar street rod.


This one was a real beauty with only 3300 miles! Whenever possible I take the cluster from the car and wire it up to get the true mileage; a little safer than just taking someones word for it!


The customer wanted all of the "bells and whistles" so we set him up with the full ETC (electronic throttle control) conversion. No cables coming thru the firewall, simple 4 wire cruise control hookup; a really slick option!
Here's the business end of the harness showing the electronic pedal and the EASY wiring hookup that's part of our harnesses.

Packages like this don't show up here everyday, and this one was sold in 4 days!!!

I just brought my LS1 swap project back from Mufflex having an exhaust system fabricated, greatly appreciate all your advice, and the benchtop programming harness really did the trick.
