7 pin trailer plug install

Ok all

I have the AEV rear bumper and I need to install a 7 pin trailer plug in the bumper, not hanging down from the bumper. What I need to do is make a hole (1.5") for the plug in. How do I make a hole that big without damaging anything else.

Thanks
Brandi

I would not drill into the bumper unless AEV shows you where and approves it. A whole that size could compromise the integrity of the bumper. Looking at other owners photos they mostly all show a 4 pin hanging off the bumper, why can't you put a 7pin there? It should be protected by the hitch itself.

I did that to my LOD bumper and love it.

They did it for me so no idea how it was done.

I don't want to hang it on the bumper, because I have all ready done that and have nearly ripped it off wheeling. It was a good idea while it lasted. Thanks for responding.

I like the idea, but the steel is kinda thick, will a hole saw work on something that thick? I have seen them used on wood, but steel????

Thanks for the idea.

I've used hole saws on 1/4" steel plate with no problems. Just make sure you're using one made for steel.

Not sure how the aev mounts but I cant see this causing any structural issues.

That being said, I do agree a quick call to AEV would be advised just to be safe.

FYI, this is what the cutout in my LOD looked like using a mopar 7-pin harness.

I work at a fab shop and use hole saws on 3/8" steel all the time for light boxes. No problem. Use a metal saw and cutting oil. Lots of cutting oil. And a plug in drill would be best. Or air drill if you have a compressor big enough. If you use a cordless, have lots of batteries. It will eat them up fast.

I drilled into my AEV rear bumper to mount a backup camera using a metal hole saw. No issue with strength. Used a large cordless drill. No problem doing it on one charge. Good idea to mount the 7 pin in the bumper.

Update: first off, thanks for the great idea on the hole saw. I found one at Harbor Freight for $30 some dollars. First off, this gal is not into full blown mechanic'n, so having multiple batteries for a cordless drill isn't going to happen or a compressor tank for air tools. :-) Maybe if I find the right guy, I can inherit the tools. But.....that hasn't happened yet. Attached, if I did it right, are photos of the start and the middle of the project. I have to keep charging the battery. LOL! This may take a couple of days to complete. Then I have to take out all the wiring and add in heavier 12v and ground wires. I just don't get enough volts to keep the fridge happy when it's hot out on the road. I don't run gas on the road. I'll post when it's done. This gal says thanks guys for the advise.

I see a different method was used before the hole saw...
But your getting it now.
Looks like you've got this under control. And yeah, I figured the cordless drill would take a while for charging. I use hole saws all the time, but only once with a cordless drill.
Anyway, good luck and glad to help.
