I can't take a pic of mine because you can't see em. I mounted them together on a bracket and then mounted them to the firewall underneath/behind the big fuse box in the engine compartment. Completely hidden. My cai pretty much covers the fuel line coming out of the fuel rail, and the nozzle goes into the back side of the cai tube about 6" from the throttlebody. Black tape on everything. I leave my hood open at the races and not once has anyone found it.
The relay is in the fuse box, there's an open spot that's just made for it. All the wiring is back up underneath or inside the fuse box. Took about 4 hrs to do the whole thing, but it's well worth it when I win a race and someone checks out my car and says "no turbo, no nitrous, damn he's just fast"
I mounted the solenoids under the windshield wipers. I mounted the injector directly into the throttle body. I am running a JR Supercharger, so the possible air flow problem with mounting the injectors to the throttle body goes away.
