Sean Clark, from mp3Car, shows us how the various components in the vehicle are wired. Getting power cables through the firewall is one of the more difficult aspects of any install. In this case, drilling through the firewall of the Altima in the wheel well proves to be the best option. Be sure to use plenty of fire-retardant adhesive on these holes once the wires are fed through. Running the power cables to the trunk can be done along the sill of the driver door. Use care when prying the panel loose. A trim removal tool is recommended to prevent scratching of your OEM parts. The backup camera switching wire and accessory turn on wire are also run along the driver door sill. Wires that aren't associated with powering any device are run along the passenger side sill to prevent interference. These include the front speaker wires, an HDMI video cable, a USB touch cable, a USB iPhone cable, a USB OBD-II cable, a USB cable for an aux input, and a microphone 3.5mm audio cable.

if you've got a link to them that would be great.

i believe the ones i have always used are Gardner Bender brand, and i thought they used 3m adhesive.

I think that might be brand, maybe age too? I'll hafta look at what I have. I got some one time that were sub par, but ever since I've used all sizes of the same brand, and the adhesive tape on these is ridiculous. When you do need to take one off, you have to pry it so hard you go thru the plastic before it comes off, and you peel from the middle where you ripped thru the plastic. Heat, cold, vibration, damp conditions on fiberglass in a boat, never had one with the good adhesive fail. It actually ****es me off more often because they are such a btch to remove. They take paint off the firewall, and if you don't soak them first, you will scratch the crap out of your boat removing them. I think the plastic part is the same for most brands, just different adhesive tape, i'll look and see if the good ones say 3M or whatever on the peel off. I have used a couple on my quad, and I run that thing completely under the water so deep I hafta stand on the rack to keep the back tires from floating, and they haven't let go yet. All the factory installed clamps and wire guides didn't last long once I put a snorkel on it, but these are more likely to cause me grief because I need to remove one than one falling off allowing a wire to get cooked. They are such a dumb little thing, but I don't know how I never knew about them until a year ago, I was shooting screws thru everything like you were saying.

The ones you stick to the firewall (or wherever) and it gives you a nice point made for a wire-tie, without messing with anything else by pulling on it so hard to tighten the tie, those are great too! I had been using the wire-ties with the loop above the 'head' to shoot a screw thru, how dumb was that, shootn screws thru stuff when there are wonderful sticky squares out there..
