CURT 58145 Heavy-Duty Trailer-Side 7-Pin RV Blade Wiring Harness Connector Black

Effectively repaired the frayed end of a 27’ forest River trailer with this item. Was fairly easy and solved the issue. Did watch a couple YouTube tutorials as there are no instructions included.

I love Curt products and this was no exception. It does not come with a wiring diagram, but it is easily found on the website. The clamp holds the cable well.

Although my wiring is different than what is molded into this plug, I just followed the same pattern mine were already and used a paint marker to mark what wires go in each spot in case the wire gets ripped out again from getting hooked on my lower hitch. This unit is much easier to plug in and unplug than the traditional plugs.Update: I hooked the cable on my lower ball hitch again because I forgot and left it on, and ripped the wires out from this plug also. But, because I had marked all the hookups with a paint marker it only took a matter of minutes to refasten my wires. Also, nothing was broken inside of this plug!! I highly recommend and will be buying myself a spare just in case.

It works fine, comfortable grip, the only thing is that it's plastic. And the mating surfaces run down the middle, so when you go to tighten the whole thing... you can't tighten it much.

A little tricky to attach the trailer wires to terminals.

This is a superior solution to the regular Curt 58140 types where the wired side of the connector is retained in the housing by an allen screw. A step farther would be to replace the entire trailer pigtail with a molded connector at a much higher cost or at the very least splice a shorter length of pigtail with the molded connector.The 58145 separates into 2 halves from the rear with interlocks on the wired side that prevent the wired side from pulling out when the plug is removed from the tow vehicle. The only nit I have with the 58145 is the polished chrome type surface where the trailer wire connections are made. It seems to me that some electrolysis could take place between the copper wiring and the connector if moisture gets in. I tried to mitigate that by applying a very thin coat of conductive grease to the surface connections before tightening the screws and then applied a thin coat of NCP-2 corrosion preventive to each connection. Where the 6-7 wires enter the plug and the seams where the halves join would need some attention to make it more water resistant. If the wires are encased in a single cable housing, this is less of a concern, but the seams would need some attention. No big deal, just a heads up. Will check it after a wet season to see how it fared. Either way, superior to the 58140.I am a real fan of the grip feature for pulling the plug from the tow vehicle connector. A nice positive feel.Pros:--Easy to install--wired side won't pull out from housing as with allen screw secured type 58140--nice gripping surface for removal of plug from tow vehicle connectorCon:--Not an entirely water resistant solution, but can be made relatively so.--potential for electrolysis type corrosion longer term. Can possibly be mitigated.

Absolute piece of garbage. The flawed design allows the top part of the plug to be easily pulled out of the main body regardless of how hard you tighten the screw that holds the pieces together. Curt makes great hitches but these plugs are an abomination.

Item was as advertised, good quality and arrived on time!

Difficile de savoir pour un débutant quand il n'y a pas de shéma mais quand vous regardez avec une loupe, les couleurs sont inscrites en anglais en très petits sur les petits bouts de métal pour vous aider à connecter les bons files à la bonne place.

Es bueno pero muy sencillo ,hasta la fecha a resistido

Working great

It’s great but they should have included a small card with a trailer pin wire diagram. They have them online but still.

excellent
