Selling a a pair of brand custom conversion harness for 2007-12 GMC Acadia originally equipped with HID XENON To change to a HALOGEN headlight assembly.  This will only work with cars originally with HID that now have halogen headlights being installed (either new OEM or aftermarket but for halogen applications).  Daytime running light function  will only work with custom programming.  

Harnesses are hand made  with OE quality housings terminals and seals.  Wire used is mil-spec tefzel wire, common in aviation & motorsports, which is made of tinned copper strands.  This allows for better corrosion resistance, excellent conductivity & makes repairing/soldering much easier.  The wire has a Teflon like insulation that is extremely durable compared to standard automotive grade wire.  Most connector pigtails sold by others do not offer these properties.
