Hi All,

Like title says, I need help bringing wire from battery to inside near head unit. Is there a easy access from under the hood to bring cable in? I didn't look enough as i am not expert but wanted to do this mod myself. If anyone has picture or place that i can look under the hood it would be great.

Stick your head under the driver side dash and look on the side behind the fuse box area.

There should be 3 rubber grommets. I think depending on which model you have, there should be 2 that are unused.

Pop one out, push the wire through and that will lead to the fender area.

Remove some clips in the fender area (these break easily so you might just buy some replacement ones ahead of time) enough to get in there. This is easier if you jack the car up on the driver side, but its still doable without doing that. Just turn your wheel all the way to the left if you're not going to jack it up, but its still a PITA.

Reach way up, grab the power wire you fed into that area and continue feeding the wire up in the engine bay.

There's a black plastic cover on the driver side edge (if you're looking in your engine bay, its all the way to the right side). This is where your wire is going to pop out.

Make sure to put a grommet around the wire where it passes through to the fender area so the metal doesn't damage the wire over time. You can replace the stock factory grommet with one that fits your wire gauge or cut a hole in the factory one and feed the wire through, then run a bead of silicone around the wire.

Its best practice to loom the power cable from your battery connection to where it enters in the fender area.

This is the easiest way to do it. Get some silicone and cut a hole on the grommet just big enough to force the wire trough and seal with silicone. Or get an universal watertight grommet that fits the hole (you might want to take the factory one as an example for fitment.

Thank you all let me give a try this weekend and I will report back to you.

Just a hint, there's another grommet in the wheel cover that leads to a big piece of foam, if you find it, put the cover back on and keep looking for a smaller grommet. It took me about 30 minutes to find it. Had to use a flashlight in the whole from the inside just to see it outside by following the light. Also, I dropped the cable from the top to the wheel well and feed trough the whole to the inside. I'll get some pictures for you in 20min.

Excellent advice!

Thank you thank you...Thank you.. I didn't get chance today but definitely follow up with you this should be good enough.

Alright found those two hole that you guys mentioned. Now I need to follow your instructions to pull the wire to battery.

Go ahead, be patient and everyone can do it.

Be sure to have a fuse in that wire.

I don't think I need bcz I'm not doing amp or sub. This will be the power supply to EDFC controller that control my TEIN'SA damping.

You always need to fuse the power wire within 18" or less to the power source.

Fusing protects the wire from receiving more power than the wire is rated. Otherwise it becomes a fire hazard in your engine bay.

If you're just running 12 gauge or whatever, an inline waterproof fuse is like $5.

Ok I didn't know that, I will have to check the wires that come with to see whether they have fuse or not. According to diagram it's all plug and play so I'm not sure where I will add the fuse if I have too. I'm working until Tuesday so I will lay down wires and stuff to see what's needs to be done.

Again thanks for the feedback I appreciate it.

Gotcha.

That kit is going to have a inline fuse already on it then.

Here are some pics from when I ran my power wire.

Jacking up the front left of the car made all the difference. Until I jacked it up, I spent hours trying to find the wire on the other side. Once I jacked it up, it took a couple of minutes.

In the pic you can see that I picked the top grommet hole. I later went back and used the bottom most of the three to stay away from that sharp sheetmetal edge inside the fender.

You can also see that I just picked a drill bit just a bit smaller than the wire and drilled a hole in the grommet by hand. Wire fits nice and snug and have had zero issues with any water getting in. You could seal it with silicone if you really wanted.

the safest way is to drill the firewall where clutch pedal goes if your car is automatic

 

[broly10000]

I drilled through the firewall in what was my 2010 but on my 2016 the grommet saved me about 1hr of looking for the spot, drilling and smoothing the hole, then finding a grommet to make it watertight.

Here it is. [emoji1] [emoji2]

Thanks for the nice pics. Now I need to find time to do all the wiring.

The fuse also protects in case of the power wire touches ground. For example it rubs thru at a metal spot, you have 12volts to ground and it will just burn. That's why its important to make sure you protect the wire when going into the fire wall as well.
