Alrighty, got the front grille LEDs working again- just a connection that was pulled loose . . . all is right in the world of bright, flashy lights again . . . .
I also installed the CB antenna onto the front brush guard, on the horizontal plate that the PIAAs are mounted on . . . just drilled the hole right into the front of the platform, which is angled downward slightly, so that when the antenna is screwed in (a fiberglass top-loaded, like Bobby's), it is angled slightly away from the front of the truck. I'm afraid to turn the unit on and screw it up before it is tuned, but the communications store that sold me the antenna (and gave me a full refund on all the stuff I bought already, even what we opened), will tune it for free for me . . . .
Looking forward to using it on an off-road trip this weekend, if any of you are bored this Saturday you can come up to my neck of the woods for a good, stock-vehicle trip. (2 hours from Bobby's garage).
I'll report back about the tires, but so far, they are great. Thanks for everyone's help, esp. Bobby's.
