Here's what you do for an ideal dashcam installation:

• Secure the wires to the windshield near the top of the rearview mirror stalk using something like this.
  
  
• Use a plastic trim tool to push the wires into the gap between the headliner and the windshield.
  
  
• Run the wires along that gap to the driver's side A-pillar, and use the same tool to hide the wires behind the A-pillar trim panel. Run the wires from the top of the A-pillar down to the floor.
  
  
• Remove the door sills and route the rear camera wire underneath them to the back of the car. Find the best route from there to the rear camera.
  
  POWER CABLE OPTION A (quick and sloppy)
  
  
• Use zip ties to route the 12V power cable through the area behind the steering wheel and plug it into the power outlet on the center console.
  
  POWER CABLE OPTION B (looks like it came that way from the factory)
  
  
• Route the 12V power cable to the passenger compartment fuse box (below and to the left of the steering wheel).
  
  
• Cut the cigarette lighter adapter off the end of the power cable, and separate the two wires within. Identify which wire is the 12V+ power and which is the ground.
  
  
• Use a fuse tap (with a 3A fuse) to connect the 12V+ wire to the cigarette lighter socket fuse (Fuse 7 in the 2018 Impreza, I think).
  
  
• Secure the ground wire somewhere appropriate. Any bare metal surface that's connected to the body should work. Put a crimp-on ring terminal on it, and either sandwich that underneath an existing screw/bolt, or use a self-tapping screw to install it somewhere.

I got a pack of [these] (https://www.amazon.com/dp/B015GYN38A/ref=cm_sw_r_other_awd_76MPwb4TCY4GW) so not to compromise existing circuits. Worked great for my A118C

I can answer the dashcam wiring for you. Best way that I have found is to use a fuse tap like this.

You will also need the appropriate fuse for that particular dashcam. And you will need a 12V to 5V converter for the dashcam. Like this.

PS: Best part about this one is that you can install an inline fuse, which is much easier to find an appropriate rated fuse than it is with the automotive fuses.

The only other wiring is connecting both fog lights together and passing the fire wall. The wire has the two connectors for the lights, 2 grounds, and comes together to connect with the fog light line by the the reservoir.

I'd take some pictures, but I needed to put the bumper back on..
The eBay kit came with another set of wires but that was just an extension in case the fog light line was too far away. So the only other wiring is the harness in the pictures.
Would you like more detailed picture of that?

I know the green plug is for the button and I'm assuming black for ground.
The little black box things with the two red wires does have a 15 amp fuse in it.

It was just confusing me that the two red wires had connectors on them.

What is the proper way for finding wires with the correct Volts and Amps?


In order to avoid the splicing, could i use something like this?

Typically no since there might be a 'spot' in the plastic molding of the fuse block, but if there are no metal contacts underneath, short of taking the whole fuse block out and modding it, you can't get there from here.

Most fuse blocks are setup to have a power 'bus' which connects the input side of the fuses to switched and/or constant battery power, but I've never seen a way to add a bus that's not there.

There are many 'add-a-tap' products that let you piggyback off another fused circuit. Ideally choose a less-critical circuit like your radio power circuit to hack into.

That's fine provided you're adding the fuse properly. Do NOT use this style. You should be using this style instead. Ensure the fuse amperage you add never exceeds factory and doesn't exceed the current carrying capacity of the wire gauge you run. That power pack doesn't pull much juice. Under 10A with music. Don't forget a proper ground too.
