Previous owner of my S2K didn't want to replace the OEM ballast on the drivers side so rerouted an aftermarket ballast terribly causing my power from the headlight relay to be cut and is far to corroded to be saved. Was wondering if anyone had any tips on how hard this would be to install or maybe even a contact that has a new harness. All I can find are used harnesses and not sure about whether they are going to work or just put me in a worse situation. The part number is 32120S2AA00 for reference and any help would be appreciated.
