My blinker hood is original, mine are painted same color as car (red), I've never seen them not the color of the car.
The wires for both meet up on the left drivers side and the wires feed through a round hole in the under hood framing just under the left one. They come back out of a round hole just below it close to the rear of the hood. 3 wires, one grounds to a screw on the cowl panel concealed when the hood is closed, the other 2 go to a 2 prong plug that connects into the wiring harness that leads through the firewall between the brake MC and inner fender corner. The harness is sold by most suppliers, if yours wasn't original you will have to read wiring schematics to figure out where to tap in and get a signal from the turn signals and hazard switch.
