6th Gen 4Runner Hybrid Switch Install & 12V Relocation Wiring Guide

Cali Raised LED Switch & Bezel + KC Lights Switch Tray Wiring Guide: 12V Relocation Cargo Area -> Engine Bay​

Since Toyota forgot to include the pigtails for my Aux switches, I figured I would install a switch. I will end up needing more than 4 switches anyway. They really should include eight Aux switches from the factory. But with the 8 switches on the Cali Raised Switch + the four factory Aux switches, we should be covered. Hopefully.

We're using the Cali Raised Switch Bezel, plus the 8-gang switch that's designed to go in the bezel. It's basically an Auxbeam, although repackaged a bit differently, and has no branding on the actual switch itself, which I like.

For the tray, we're using the KC HiLiTES tray designed for the 4th Gen Tacoma and 250 Series Land Cruiser, but it works on the 6th Gen 4Runner as well.

Find them online:

I'll include a tools and materials list once the post is drafted.

1. Mock Up Tray With Accessories​

I started by mocking up the tray with the switch and breaker. We're still using the KC Lights rock light kit, however, we're just going to wire everything to the switch instead of using their bus bar and ground terminal. The Cali Raised Switch comes with an inline breaker, but instead, we're using a Blue Sea 150-amp breaker. I had a couple of 150-amps on hand, but you can use a 100-amp if you're buying one. You don't need more than 100 amps for this switch. I did need to drill a few new holes in the tray to position the switch and the breaker where I wanted them. The bolt that connects the tray to the leg support will go through the breaker. This allowed me to keep one of the slots in the tray open so that I can run leads under the tray up into the desired swicth terminals.

Now that we have the switch, tray, and breaker positioned, we can start to run all the wires through the firewall.

2. Run Wires Through Firewall​

I used two 4-gauge wires about 15' in length each, wrapped them in a braided sleeve, and then marked each of the positive ends with some red heat shrink so that I know which leads are which. Because of the run distance, you want to use 4-gauge. You might be able to get away with 6-gauge wire if you don't plan on big, consistent amp draws. Check out this amp draw chart for reference.

Since the switch is rated for a 60-amp consistent draw and it's a 15' run, the 4-gauge is probably overkill, but better safe than sorry.

This firewall is a bit different than the 5th Gen 4Runner. It's tighter, and there is more stuff in the way, so you can't punch a hole through the main opening as easily. We ended up punching a new hole in the firewall grommet. Once the main leads are wired to the tray, we will come back with PERMATEX RTV (silicone gasket maker) and seal anything if we feel it's needed.

3. Remove Front Seat Kick Panels​

The new plastics on the 6th Gen are easier to remove, and there are no clips to break, which is nice. The panels have tabs that slot into place. Gently pull up on them and they pop right off.

4. Remove Back Seat Kick Panels​

5. Remove Battery Cover Plastics Behind Seat​

There are two caps on this cover. Pop those covers off, and remove the plastic nut on the bolt. Then remove the vetical cover on the passenger side. Once the caps and cover are off, release the clips.

6. Release Battery Cover Clips​

If you don't have a set, grab some Gear Wrench clip removal tools. They will save your clips. Thank me later.

7. Remove Seat Latch Cover​

In order to fish the wire under the carpet, I opted to also remove the plastic cover on the seat latch.

8. Prepare 4-Gauge Leads​

Since we have two big 4-gauge wires, I taped them together to make fishing the lead a bit easier.

9. Fish Leads Under B-Pillar Plastics​

From the driver's seat, you want to fish the leads under the B-pillar plastics into the backseat. If it gets stuck, adjust your line and keep pushing it through until you can grab the end with a pair of needle-nose pliers.

10. Fish Leads Under C-Pillar Carpet​

Now that you have the leads in the backseat, fish them under the plastics and under the carpet into the seat latch opening. Pull the lead all the way through and then work the lead back under the carpet into the cargo area.

11. Fish Leads Into Cargo Area​

From here, just work the leads up underneath the cargo area plastics. You can see the lead coming out of the plastics on the left-hand side heading towards the battery.

12. Fish Leads Into Battery Compartment​

Finally, just work the leads underneath all the plastics and up into the battery compartment. Now it's time to finalize the position of your leads. Zip-tie any location that you can in order for the leads to stay in place. If you see an opening and access to the leads, zip-tie them in place to the other battery leads and/or any plastic clips in place.

13. Run Switch Cable Through Firewall​

Feed your switch controller wire through the firewall and prepare the bezel for the Cali Raised LED switch bezel install.

14. Remove Factory Bezel​

15. Remove Side Cover Plastics​

There is a small opening behind the bezel that will allow you to fish the switch lead through. I tried to avoid removing any other plastics, but it's much easier if you remove the side cover. Tape the switch lead to a fisher line and pull it through as shown above.

Working on the rest of the install now.... standby for updates.

You can add this product as an add-on when buying the bezel. I would assume an Auxbeam fits in there as well, but I have not tested that yet.

16. Connect Switch & Bezel​

Remove two of the orange tabs from the OEM bezel and swap those over to the new bezel. Connect the switch and then install the bezel.

17. Clean Up Switch Wires​

Take the slack from the switch wire, zip-tie it together, and find a spot to mount them. Don't forget to take all the slack from the engine bay into the cabin so you can hide all the wires behind the dash.

18. Testing The Switch​

I tested the switch again, now that I had everything close to where it needed to be. I temporarily used a circuit in the engine bay fuse box to test the ACC function on the switch, however, I will be wiring the ACC lead to a fuse inside the cabin.

You can use any fuse that's on via Accessory, this could be IGN (ignition), ACC (Accessory), or even something like a tail light fuse (TAIL). For testing the setup in the engine bay, I used the IGN fuse, and it works, but the add-a-fuse sits at a weird angle and didn't seat very well. Plus, add-a-fuses in the engine bay never look clean in my opinion. You end up having a wire coming out of the fuse box, and then the fuse box doesn't close correctly. And finally, no one has any fuse box risers out of the 6th Gen 4Runner yet, so with all that said, let's run the ACC wire inside the cabin.

19. Run ACC Lead Into Cabin​

This is the last wire that needs to go through the firewall. Once you have the lead through the firewall, add a 16-gauge extension wire, and braided-sleeve the whole wire. Then finish the end with some Tessa Tape or electrical tape. Finally, fish the wire through from the drivers side to the passenger side. I connected the Add-a-fuse to the tail light 10-amp fuse location.

19. Connect Power & Ground Leads to Switch​

Now, just cut your main power and ground leads to size, crimp your ring terminals, and hook everything up.

20. Connect Power & Ground Leads to Battery​

Finally, cut your leads to size and hook them up to the battery.
