: Where to push wiring through firewall?

I'm working on wiring up fog lights and was wondering where to push some wires through the firewall? Is there a relatively easy to get at spot to push through two or three 18-gauge wires? I'd REALLY rather not have to drill...:twisted:

Benny,

After 8000 plus posts you would think the man knew how to use the search button. :rolleyes:

I never frequent the electrical forum, as electrical is REALLY not my thing. Trying to learn though.

And let's be honest, the search on here sucks :mad:

No. Drilling is easier by far. Just make sure to use a weather proof bushing.

The Fogs have a wire provided by Honda!!!

YOU DON'T NEED TO PUSH ANY WIRES THROUGH THE FIREWALL!!!

IT IS MARKED UNDER THE HOOD WITH BLUE TAPE. IT'S MARKED UNDER THE DASH WITH BLUE TAPE.

What type of lights are you installing? Are they Honda or aftermarket?

All you need is the trigger wire for the relay to go through the fire wall.

It's even easier than that! Come to Harpers Ferry and we will install them for you!

Aftermarket, I do NOT want to pay the exorbitant rate to get the factory fogs! :mad:

Besides they're bumper-mounted to leave room for bigger lights in the stock fog alcove later :D

There's an easier way. Look above your gas pedal, you'll see a white wire, it runs into the engine compartment. It has a grommet with a nipple on the engine side. Trim off the nipple and could can fit you fog light wires through. I have my fog light wires and trigger for my DRL's running through this hole. Because its near the fuse box, you don't have to run the wire far.

Another stupid question (I warned you I'm an electrical dunce....):

In the under-dash fuse box, there's a lot of spaces for fuses that aren't used. Can I assume they're all live and if I get an appropriately-sized fuse and stuff in it, I can wire directly off of it to the switch instead of running from the battery?

(cue the ridicule in 3...2...1...)

I just realized I can't wire it quite this way, I can't use the OEM fog light switch. On the 07+, the fog light switch is integrated into the multifunction stalk on the left, the one that controls the turn signals. You get a new one to attach when you order the OEM fog lights. So I'm down to the cheapie included switch instead.

I know its easier to just ask others, but you can learn alot by searching the site on a regular basis. I know it takes alot of time, but you'll usually find what you want, also you run across good ideas and tips that you didn't think of. I think this is what you're looking for. Read #4.

No ridicule, it's a damn good question - actually one I wished I had the answer for. Theoretically you're correct, in actuality I'm just plain not sure. Looking through the Electrical Troubleshooting Manual I've seen instances where simply popin' a fuse in the unused locations would indeed give you a dedicated output - so yes it should work...

problem is, I haven't disassembled the UDFR box to tell you if it even has the terminals for the 'missing' fuses. I have had the thing out of the E, when I was working on one mod or another, but I didn't have the time to disassemble it and really do any reverse-engineering. Now, If anyone out there happens to have one layin' around... :rolleyes:

I'm certain there are all kinds of neat-o things that we can do with that mysterious black box if we can just get into one long enough to check it out...

My only 10 cents on this is make sure you weather proof any holes you create or use through the fire wall. I had an RV Dealer install an electric brake package for my Tent trailer and they forgot to plug the hole. After the first rainstorm I ended up with a couple inches of water on the floor. Live and learn I guess. :rolleyes:

Thanks Ayf, Dan, & Benny for the great info. Yes, I can search just like everyone else, however at least for the firewall question it appeared there was quite a few different answers and it's nice to get them all gathered in more or less one place. As for the fuse box question, I'll wear the dunce hat for not at least paging through the mobile electronics forum as I see the thread Ayf recommended is relatively recent :sad:

The reason I suggested "searching" was that I found many ideas that I never thought of. The grommet in the firewall was posted by someone else. Also the leds I put in was due to what others did. It's amazing the amount of knowledgeable and ingenius people we have in this forum. Glad to help, because so many of you have helped me.:D

So in reality to get these lights hooked up all I have to do is run one wire from the lights to the switch, then the power and ground can be done from under the dash. Brilliant! :D

You don't need to run ground all the way to the switch, just from the lights to the nearest good spot.

The switch that comes with this has to be grounded also, as well as the lights. Don't ask me why, I just read the wiring diagram and do as they say :twisted:

Yes, but as Dom would say, "Ground is ground the whole world 'round!" Run a ground wire from the switch (so its little pilot light will work) to another convenient spot. It doesn't have to be the same wire as the one grounding the fogs!

Twi.

I would just use the wire provided for the fogs, and save yourself some time.

Also, it has been my experience that the inexpensive switches do not last well when your pushing a load through them. I would just use a relay under the hood to feed the power from the battery. Use the fog wire with the blue tape to trigger the relay.

You will save yourself some headaches by doing that.

Oh by the way,
The switch I used for mine is an aftermarket, not Honda.

I had figured that out long ago :D I'll just run the ground from the switch to a convenient screw somewhere under the dash, then ground the fogs probably on the lower fender crossbeam or somewhere similar.

I'm actually thinking about picking up an aftermarket switch anyway, something that'll blend in a bit better. Do you know off the top of your head where the stock fog wire comes out in the engine compartment? That would indeed save time if I could just tap into that.

Sorry, I almost forgot to add that the way it's shown in the drawing I submitted in the earlier post, allows you to run the fogs with the parking lights on, without the headlights. Or with the headlights on. I find that useful in heavy fog. The white lights bounce off the fog and kill the visibility.

I'm planning to power them completely independently anyway. By the time I'm done with my E modding the dash is gonna look like a plane c0ckpit :lol:
