• Mounting a 7-Way Bracket and Routing Wires Through the Firewall on a 2009 Hyundai Santa Fe
  As far as mounting the 7-Way bracket that comes with # ETBC7 I recommend adding the no-drill long bracket, # 18136. Attach it to the hitch and the ETBC7 bracket to it. As far as going through the firewall on the vehicle if you are able to route it through one of those spots you mentioned, that would be ideal. You may need to tape the wires to the end of a straightened coat hanger and then push the opposite end through the spot and into the cab. Then you would need to go into the cab and...

• How to Install an Aftermarket Brake Controller on a 2015 Chevroet Tahoe with OEM Brake Controller
  That is correct, because your OEM brake controller is not compatible with electric over hydraulic brakes, the Prodigy P3 brake controller, # 90195, and the Plug-In Wiring Adapter, # 3016, will work in your 2015 Tahoe and allow you to use the Titan Disc Brake Kit with Electric-Hydraulic Actuator, # T4843800. Since your Tahoe has the OEM brake controller installed in it there are a couple of more steps you will need to take to make sure you do not get codes on the vehicle's computers and...

• Installing Hopkins Smart Hitch Backup Camera Without Cutting Through Floor
  If you are referring to the Hopkins Smart Hitch Backup Camera and Hitch Aligner System # HM50002, depending on your vehicle, you may be able to go through the firewall which you can drill in order to run the cable from the monitor back to the camera without going through your rubber floor. Anytime wiring passes through the firewall, the opening should have a grommet # SWC8055 and sealant # LT37464 to prevent the metal from wearing away the wire insulation and possibly causing a short...

• How to Install a Prodigy P2 90885 Brake Controller in a 2014 Kia Sorento
  To install the wires of the # ETBC7 that get run to the battery of your 2014 Kia Sorento so that you can install the Prodigy P2 Brake Controller part # 90885 you will need to look for a grommet or knockout in the firewall to route the white brake wire into the cab. If none is available, you can drill a hole on a section of the firewall where there is no obstruction on either side.

• Brake Controller Installation Details and Running Wires on a 2002 GMC 2500 Pickup
  The best practice for running wires through the firewall on your 2002 GMC 2500 HD pickup, is to find an existing opening that has a grommet and use that. You'll also want to make sure that you keep the wiring well away from any moving or hot parts. In the absence of an existing opening, you might have to drill to make your own. In that case, make sure you are aware of what is behind the spot where you plan to drill, so you don't drill through anything important. You will need to use a...

• Routing the Wires Through the Firewall When Installing an ETBC-7 Kit on 2004 Honda Pilot
  If you are unable to locate an existing grommet or knockout in the firewall, you will need to drill a hole in order to route the wires through the firewall of your 2004 Honda Pilot. After drilling the hole you will want to install a grommet like # SWC8055 to prevent the wires from rubbing on the metal. I have attached our ETBC-7 help article and also included a snapshot of this article which illustrates this step. In order to prevent fumes/gases from entering your vehicle, I also recommend...

• Where to Route Backup camera Wire Through Firewall on a 2011 Toyota Tundra
  You can look for another wiring harness that goes from the interior of the vehicle, through the firewall, and into the engine compartment. That would be the most likely place. It can be tough to get anything to go through those pre-existing locations. If you were to straighten out a wire hanger and work it through you could then tie the wire to the hanger and pull it through. Otherwise you will have to drill a small hole through the firewall. Just be careful not to drill through anything...

• Recommended Path to Connect 4-Way Wiring Harness on 2012 Mitsubishi Outlander to 7-Way ETBC7
  I can help you route your 4-way to the # ETBC7. First thing I would search the cargo area where your wiring harness connector is for a factory grommet to get the 4-pole through. If there is no grommet the best thing to do is to drill a small access hole to run the wires through. I recommend using the snap bushing grommet # SWC8055 and instead of splicing into your vehicles harness (voids the warranty), I recommend making the splice and reconnection in the 4-way to 4-way loop # HM48145....

• How to Route Roadmaster Tow Bar Wiring Harness Part # RM-154 in a 2007 Saturn Ion
  The Roadmaster Tow Bar Wiring Harness Part # RM-154 requires that you locate holes through which you can pass the 4-pole RV connector wiring. It is usually possible to locate rubber grommets that already have wiring passing through them if you remove carpet and trim panels in the rear of the vehicle. The tail light wiring may also provide an access point; you can try removing the driver-side taillight assembly to see if there is a grommet you can use. Once routed to the underside of the...

• Running Wires Thru Firewall to Install Optronics Light Kit XIL-OEA0713JKCP on 2013 Nissan Frontier
  The best-case scenario would be if you could find an existing grommet that passes through the firewall. There will be one somewhere on the firewall that allows the main wiring harness to pass from the engine compartment to the passenger cab. When you find an existing grommet, use a small knife to cut or poke a small slit in the rubber, being careful not to nick any wiring running nearby. If you cannot find a grommet on the firewall, look under the truck, on the floor pan. If you find a...

• Tips for Routing a Trailer Wiring Harness through the Firewall on a 2017 Toyota RAV4
  If there is already a harness that goes through the firewall and that is easy to get to/work with then you can use that though it may require some persuasion to get the wire through. Otherwise drilling a small hole, running the wire through, and then sealing up the hole with silicone is the way to go. Just be careful not to drill through anything on the other side of the firewall! What I recommend is to drill a hole a little smaller than 9/16 and then put grommet # SWC8055 in the hole....

• Routing the Monitor Wire Into Cab of Toyota Tundra for Hopkins Smart Hitch Backup Camera
  We have not had the chance to install the Hopkins Smart Hitch Backup Camera # HM50002 on a Toyota Tundra, so unfortunately we do not have an installation video. I recommend checking for an existing grommet in the firewall of the cab, likely behind the pedals on the floorboard. Using an existing hole in the firewall will help save time on installation. I have attached an installation video showing the wire being ran through an existing grommet. If you cannot find a manufacturer's grommet...
