Video Transcript for Spectro Snap Bushing Grommet Review

Today we're going to review and install the Spectro Snap Bushing, part number SWC8055. Note, the snap bushing is available in two sizes: the 7/16 inside diameter and a 9/16 inside diameter, part number SWC8057. Here's what our Spectro snap bushing looks like. This is a nylon bushing that will help protect our wiring as it passes through our pre-drilled hole. Typically that hole is drilled into sheet metal like a firewall. The raw edges of the metal can chafe or dig into the wiring or even an air line, and the snap bushing will protect it. Once the snap bushing is slid through your pre-drilled hole, the locks here will help hold it in place and the face of the grommet will be on the other side of the firewall, so we'll have part of the grommet on each side holding it in position. When drilling it out, you're going to open it up to approximately a 9/16 hole.

That makes the inside diameter 7/16 and the outside overall is 21/32. The grommet itself is 13/32 thick. Our grommet is typically used in areas where there's not a lot of heat, but it will hold up to approximately 257 degrees Fahrenheit. Now with the hole drilled out, we'll go ahead and take our snap bushing and install it. Put it in the hole, push it into place, and it locks into position. We're now ready to route our wiring, air line, or whatever you need to route through the protected hole.

There you have it for the Spectro Snap Bushing, part number SWC8055.

Everything I ordered came exactly as it showed them to be but it took one of them 12 days to get here and the other one only 4 days. I don't think that is the fault of etrailer I think it's a problem with the US Postal Service. 336152

Absolutely Superb Service! On the 23rd of September at 10:10 a.m., I ordered a brake controller and several other items from the etrailer.com website. By 12:16 p.m. of the same day, I received a notification from etrailer that the order had shipped. The complete order arrived at about noon on the 26th. Ordering on the website was easy. All items were described very clearly and pictures were provided for them. The service at etrailer is absolutely superb. I would recommend this company, without hesitation, to anyone needing trailer parts or accessories. 324675

  • 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...

  • 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 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...

  • 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 #...

  • How to Wire a Trailer for Tail Lights
  • First, lets make sure you have all of the parts you need to wire a trailer for lights. If you have an old trailer and want to replace everything, I recommend using a kit like our Optronics Tail Light Kit, # TL29BK and our trailer wiring installation kit # HM51020. We also have an LED kit, # TLL9RK. Step 1 - The trailer connector should extend 2 - 3 feet past the tongue. Attach the ground wire directly to the tongue of the trailer using a self tapping screw # 101131802 and a ring terminal...

  • 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...

  • 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...

  • 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...

  • Wiring Installation Into the Custer Light Mounting Box # AL65-02
  • For the Custer Light Mounting Box - (2) 6-1/2" Long Oval Holes - Diamond Plate Pattern - Aluminum # AL65-02, you will use the PVC Grommet for 6-1/2" Oval Trailer Tail Lights # A70GB with lights like # STL22RB or # STL22AB. These lights use a pigtail like # A47PB or # A45PB. You will need to drill holes in the housing to mount and add a hole for the wiring as well. I recommend using a the Snap Bushing Grommet - 7/16" ID, 9/16" OD # SWC8055 or the Replacement Flush Mount Rubber Grommet...

  • 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...

  • Running Wires Through Firewall to Install Optronics Light Kit # QH-87CD 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...

  • 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. You will need to drill a hole to install a grommet # SWC8055 large enough for the 3 wires that will pass through. I...

  • 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...
