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 3300 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.

NOTE:  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 and telephone number on a piece of paper and place it inside the box so we can contact you after your harness has been tagged, cleaned, peeled and inspected.  We will schedule your completion date and Invoice over the phone when we have your work order call 3-4 business days after your harness arrives.  Payment can be made with credit card on the phone or via Paypal.
