I purchased a used set of Litronics from a 993 TT for my 96 C4. They did not come with with any connectors. I do have the Does anyone have any idea how they should be wired? or have done this conversion before?

 

i have a set of factory litronics installed on my cab...it should be plug and play if you are using the factory ballasts.

 

They need litronic ballasts to fire up, They are not just a plug and play swap.
