    Looking to bring in a few wires from engine bay to interior, anyone know where this can be done at? Don't want to drill any holes.

    Thanks in advance

    Ok, found a way! Open hood, drivers side near firewall there is a cover, pop it open

    Look at bottom right you will see body plug with wires loom, gently pull out the plug and route your wires. I would recommend wrapping wire(s) with friction tape to avoid wear and possible short. If adventurous unwrap existing tape, insert your wire(s) then re-tape

    Reinsert the body plug. In the interior the wire(s) will be above and to the left of the brake pedal.

    I did not wrap my wires yet as I have a couple more to bring through, but ran out of time today.

    Hope this helps!

    Harts great info. Have you considered drilling a hole through the body plug outside of the existing wires? This will allow you to get a wire (or a few wires) through the plug while not having to worry about the firewall sheet metal chafing the wires you run.

    If you go this route you can drill a hole in the plug, stick a wire hanger through the hole, give it a spray of silicone and your wires should glide right through. Finish it off with a dab of black silicone around your wires to seal it up nicely.

    I am wiring in a Curb Alert PRO Parking Sensor 5000-CA5 unit. I already installed the sensor and working on the wiring. Not having a front parking alert with the air dam is costly if we bump a parking stop! Once completed I will post step by step instructions if anyone is interested.

    That would work even better! Would have saved me all the scraps and bruises on my arm too! Thanks!

    You can probably poke a hole through that plug with an awl too rather than drilling... I haven't looked at that plug so not sure how much room there is to work there but probably not much! Maybe even file a point on a small piece of wire hanger and work that through.

    It is tight, but think I will heat up the end of a hanger and have it melt it's way through, route the wires then dab with silicone to seal it. Rotate the plug so my wires are on the bottom and don't show as much. Wish you were here earlier, could have done it that way the first time!

    I'm glad the suggestion is helpful. I'd be a bit concerned about that wire chafing over time. If it's carrying voltage that definitely won't be good.

    I can't tell you how many times I've done something only to either think of a better way or have somebody suggest a better way and then I've done it over. ;)

    YUP! wire feeds to interior and connects to "brain" and buzzer. Ran out of time today hard wiring it all up, but did test it and it works, gives beeps when I am 20 inches from a parking stop that is 3 inches or taller. With any luck I can find power under the dash and finish it up over next few days.
    Here is a closer picture of sensor, it is about 1 1/2 inches wide and about 3/4 or 1 inch tall.
