You're welcome
. I am glad I could post it for you guys so that you can get useful information before tackling this install.
I am updating this info: I should mention here that for 2013 models, there are electrical wiring that's attached to front bumper. Please use extreme caution when you take it off. If anyone with 2013 Z takes off their front bumper, please send me some pics so that I can update it. (thank you xTETOVABOYx)
