I installed the charge port under the bonnet, at the base of the windshield, passenger side. I still have to lift the bonnet to connect but can disconnet and go without lifting. Took my time with the harness making it as factory style as possible with a fuse, nylon woven wire loom, factory style lugs and a proper stress relief at the charge port bolted down with an existing bolt. I could not find a place outside the bonnet that was any easier to access and not visible or require cutting holes.
JC - Cooltech made a kit for the late 05/ 06 FGT, that hooks up to the battery and routes out front to mount in the grill location by the tow hook - no need to lift bonnet. Just have to drop the front splitter (not remove) to route the cable... Will work with your FGT as you dont have the grill that cam with early 05's
