- We cover quick easy tips to help ensure your trailer makes a good connection to your vehicle. We have XMT Construction's 2017 Chevy Silverado at the shop and we make a few minor adjustments to make a better connection.
Vehicles that tow large trailers and weight rely on the trailer's braking system to assist slowing down the vehicle. If a trailer connector is not performing properly your braking and/ or signals may be compromised. Don't let this happen to you.

This is good advice, very timely as the the ‘Holiday Warriors’ will be getting their units ready, and a clear and concise video for something that everyone that tows ‘should’ be doing, but usually doesn’t. As an electrician I have been doing this for my boat trailer religiously and also agree with the clear film application vs the dielectric grease for helping to stop corrosion! Keep up the great videos!
WyrGuy2 Nice to hear a fellow professional agrees. I live dielectric grease but not really for the trailer side. It should work fine for someone that just tows on weekends for recreation.
Clicked on this video looking for something else but stayed for this useful content, thanks for sharing! 👍
So glad you found the video helpful!
Excellent advise. Thank you!
Thanks for watching!
Great stuff thanks!
Thank you for watching!
Fluid Film is the BEST for everything 👍
Pretty much!
outstanding!
Thanks for watching!
Excellent video! After checking continuity with the test light as you did, disconnect the battery to insure you don't short any circuits while cleaning the contacts. This saves you replacing fuses if you accidentally short contacts. You can also use a traditional test light with a ground lead connected directly to trailer connector ground pin.
5th ID Thanks!
I was just curious about your response to the video why not just disconnect the fuses instead of the battery
@@mrobvious1100 It’s usually easier access to the battery and quicker than trying to locate the right fuse.
Can I just turn battery disconnect switch to off position to protect fuses?
Liking the fluid film better than dielectric but I like cleaner tools IPA trailer plug cleaning tools best. Good info.
Thank you for sharing!
thank you
You're welcome!
Great video. Can you add a checklist of everything you used?
Just use fluid film, electrical contact cleaner and a pipe cleaner.
What kind of pin tester is that? Great information, thanks !
I use a small PC of sandpaper and a fuse puller to clean my truck plug and nail files also sandpaper to clean my plug
Thanks for sharing the tip!
what beeping tester was that!? hella badass!! can you disconnect the negitive terminal so you dont short it out while cleaning!!? 🤔
I'm using a Power Probe 4. Here's a video on version 3 th-cam.com/video/Wr6abi96KCE/w-d-xo.html.
Yes you can totally disconnect the battery prior to working on the vehicle.
What's the model number of that DC current continuity tool where you only have to touch the vehicle metal?
It was a test light from SnapOn.
My 7pin has some play, I have to wedge a small piece to keep it at a certain position to keep the lights on. Any suggestion?
Rebend some of the tabs to give it back its tension?
I like that you use a gun cleaning brush for cleaning.
I definitely wouldn't use it in a firearm after. Thanks for watching!
Would smearing a little grease around the perimeter of the 7 pin connector cover help keep water out of the connector?
Yup you can use dielectric grease. It won't degrade the plastic.
Is there a cheaper circuit tester that will work? Power probe 4 is over $100.
I'm sure there is, I just haven't used them. You can also use a multimeter.
When I try them out to make sure they work the brake one is not as bright like the other ones..?
Probably need new bulbs or there's corrosion on a wire
Can I use brake clean?
Yup, that will work too.
I wish you would have shown the cans of 'fluid ??' electrical connection spray that you used. thanks!
I'm using Wurth right now. I just bought contact spray in the video shown.
@@AnthonyJ350 I think what he meant to say was you spoke mumbled when you said “fluid ----“ I didn’t understand you either.
@@wheelie642 Sorry about that. I used Fluid Film. It's safe on plastic and non-conductive.
Good video.
I had a hitch and electrical plug install performed on my Chevy Express van today. They didn’t tuck the plug unit under the bumper enough. It is sticking out past the edge of the bumper more than one inch. It is going to get damaged eventually and rain will fall on it. I will correct it tomorrow myself by drilling two new mounting holes under the bumper. Want something done right …..
Thanks so much for watching! Hope you get it all sorted out!
Plane old white vinegar and cotton buds have worked for me
Thanks for the tip!
You said "keep in mind that you have live connections in here and you don't want to short out anything". How do you avoid shorting out anything?
Disconnect the battery
Scrubbing between bibles bathroom cleaner does the trick. Spay it in plug in and it cleans the contacts up pretty good
Thanks for sharing!
I've been having problems with my boat trailer lights intermittently going on and off. All other turn signal, brake lights work fine, I suspect loose connection in the plug here, on the inner, truck side. Anyone have same issue? Thanks!
Check the ground on the trailer
Ground at the plug? or is there a ground wire for the side lights? If it was a ground problem, wouldn't I have problems with the other lights? It's just the trailer side lights.@@AnthonyJ350
More uses for Fluid Film, cool!
Most definitely! Fluid Film is amazing stuff.
@@AnthonyJ350 so much agree!
@@AnthonyJ350it didn't damage the rubber?
@@bartmankowski241 No it didn't. Fluid Film is safe for rubber and plastic.
I finally changed the fuel filter in my Ford Taurus and it was black
Was the filter in the tank or external?
AnthonyJ350 it was external
Did the car run a lot better after? I'm assuming it did.
AnthonyJ350 it ran a hell of a lot better I can do 0 to 60 in 7 Seconds
Nice!
Use a cordless screwdriver or drill ( smaller is better ) and chuck the brass brush into the cordless
There's live wires and ground in there, you risk shorting something out.
@@AnthonyJ350 there are non-conductive brushes that you can use to clean
www.brownells.com/gun-cleaning-chemicals/brushes-amp-bore-snakes/bore-brushes/heavy-weight-nylon-bore-brush-prod19581.aspx
@@cedricpod VERY INTERESTING. Thanks for the link.
its a bore cleaner for a gun
That's a tiny gun. These are like tiny pipe cleaners
AnthonyJ350 it looks like a .22 rifle bore brush
It's a barrel scrubber damn City Slickers
AnthonyJ350 It’s probably for a .22, thats definitely a barrel brush 😂😂😂
Definitely a Hoppe's 9 .22 bore brush...
I'm not getting no power in the 7 pin
This video might help th-cam.com/video/IPk6DITVvh8/w-d-xo.html
Using a gun cleaning brush is a great idea!!!
Thanks for watching!
Never use metal brush to remove corrosion, rubbing or grain alcohol as solvent, q-tip, wood tip tool, plastic brush, compressed air, seal connector with a suitable dielectric grease...Best Tim
What if you disconnect the negative terminal?
@@AnthonyJ350 dissimilar metals and micro damage to metal surfaces of contact points, clean often to prevent buildup of verdigris
@@55tt551 I agree. Isn't there a high likelihood of the trailer having dissimilar metals with its plug vs the truck?
Brush is used for semi's wrong tool for this spade pin type
Thanks for the feedback
I wouldn’t use dielectric grease because it conducts electricity and could short out the connections
It doesn't actually. I have a video testing its ability to conduct. It's safe to use in connectors.
some say dielectric grease is non-conductive
Dielectric means non-conductive
@@sgawnegmail dielectric means nonconductive.
Maybe you should google the word 'dielectric'...
wd-40 seems to work for me
Thanks for sharing!
Does it? Cause I don’t wanna go buy this stuff if I already have we-40.
still have issue . thanks
What's the issue?
@@AnthonyJ350 i have the 4 prong. It had allot of corrosion in it. I soaked it for several hours in vinegar. HUGE DIFFERENCE. but when i hooked up a LED tester. Bright clear read out, but some like left turn LED was weak. Not sure if still needs deeper cleaning or damaged has occurred from corrosion. Suggestions.. Thank you.
@@user-yv7fb8ki2v Check to see where it's grounded. You might need to soak it in Fluid Film for a few days and clean it again with a non-conductive brush.
@@AnthonyJ350 If it wasn't grounded. Wouldn't that mean nothing would work? Use the fluid film to soak wiring harness?. I was putting on light bar on back. has running, brake, sequential turn signal, and reverse. ONLY get brake, and right turn on light bar. It doesnt make sense. The LED test left is weak in being lit. but LED test on others is a strong signal. The corrosion was bad, but after soaking in vinegar appears clean from what i see. I'm wondering if the corrosion effected the wring or still needs deeper cleaning. Sorry I tried not to bore you with detail.
@@AnthonyJ350 O your referring to the ground in this case
I use my wife’s nail files
That could work
Caution: Dielectric grease is an anti-conductor. You can verify yourself by doing a continuity test. Dielectric grease is greatly misunderstood. So, think twice where you put it.
Dielectric grease has the ability to displace very easily. I do a continuity test in this video
th-cam.com/video/YgJRKlE7pYg/w-d-xo.html
Have you ever had an issue using Dielectric grease?
the grease squeezes out when plugging a connector leaving a barrier around the receptacle
That’s not brass….
Thanks for the feedback
