About  Ken Wolkens

As an engineer, I've worked on numerous GM vehicle powertrain programs when I lived in the Detroit area AKA The Motor City. As a result, I know these harnesses inside and out.

I am professional and punctual. If I say that it will be done or I will be there at a certain time you can set a watch by me. I have built over 4200 harnesses since my career began in 1994 and have numerous references and high-profile customers who will be happy to talk about the high-quality work I have done on their Stand Alone Harnesses.

Please remove everything that can be disconnected before shipping any harness for conversion.

  ECMs, TCM's, Modules, Sensors, Pedals and extra sections like the Duramax Accelerator Pedal Jumper or the Transfer Case Jumpers should not be sent.  Battery cables should also be removed if you plan to reuse.  Any extra items will be cut off and disposed.  We do not retain, stock or sell replacements of any of these items.  If you think you might want it pull it off and keep it on your end.  Finally be sure to write your name, EMAIL ADDRESS and telephone number on a piece of paper and place it inside the box so we can EMAIL you after your harness has been tagged, cleaned, peeled and inspected.  We will schedule your completion date and Invoice via EMAIL 3-4 business days after your harness arrives.  Payment of our invoice is simple and easy with any credit card or a Paypal account when the work order is completed.

                                                                                                Thanks, Ken

Shipping Instructions:

Normal Business Hours are 8AM-6PM Mon-Thurs and 8AM-2PM on Friday. (Eastern Time Zone)

We are closed Saturdays, Sundays and Holidays.

Due to labor availability constraints and to streamline efficiency, Email is our primary means of communication.  We check and respond to email multiple times daily.  If you have checked all of the website tabs including scrolling down and your question is not answered in our Q&A formats, in the Statement of Work, or in one of the 50 or so videos on the site a telephone appointment can be set up via email request.  You must detail the reason for the call in your email and we can set a time/date for a conversation.  Questions that are already answered on the website will be directed back to the site.


  • Due to limited parts availability, any Gen 5 LT harness with crash damage, missing sections or pieces must get authorization from us prior to shipping.
  • If you do not own a scan tool with live data capability you will need to purchase one and learn to use it prior to starting your engine for the first time.  Any and all tech support starts with us asking for codes and live data values.
  • We no longer support cam changes.  Mail order tuning is a recipe for failure and the best LS tuner can really botch a Gen5 tune.
  • Mix and Match "Frankenmotor" setups are not supported.  If your takeout is not complete and in stock L83/86 or LT1 configuration from a single vehicle we are unable to support your project.  See the videos for the possible mix-match failures. 
  • We do not support anything after 2019.  If you have an LT1 from a 2020 or 2021 Camaro it is the only exception as those still have the E92 ECM.  Note the transmission must be an exact match.  It is up to you to confirm this yourself by watching the videos on the FAQ tab.
