when i bought my fog light switch they threw in the harness with it for free.. i dont know you could go to the junk yard and take apart a gsr to get the harness its not too hard... i got the non hid conversion and i have it in but some of the parts came in damanged soo im working with importadreneline.com to get that resolved which it is slowly but surely... i dont know good luck with it man me and you are in the same boat and will prolly get our cars back at the same time... but ill make sure to post some pics up online for everyone when its done...
