I have the vehicle listed above SLT model with 9012 bulbs. I wish to change them back to original HID light bulbs D3 S. How much work would it be to change them? Do I have to change the wiring or use the wiring that's there?

Hello,

It looks like it might be a little involved to change it over but not anything we can't handle. Here are the headlight wiring diagrams (below) so you can see how the system works and a guide to help you test the connections.
