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.

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 3600 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.
