I took some forum advice from NetworkTV and purchased the same LED lighting from Amazon to be installed under the hood. The only difference between his install and mine is the switch & light placement. I believe NetworkTV installed a pressure switch while I installed a rocker switch to include 1 overhead light vs. 2 overhead lights. Took down the hood insulation mat, ran the wires through the cavity of the hood, following the driver's side washer line, then behind the rear engine bay valance. Hiding all the wires, then attached Power, Load & Ground to the rocker switch. I'll try to take pics at night, but either way if I don't, I am sure it'll be bright enough, especially comparing to NetworkTV's thread and his install.
