Will 12V Wire at Vehicle End Trailer Connector Be Hot Even When Truck and All Lights Are Off  

The light that indicates that the 12 volt circuit is hot is normal and it will not drain the battery. Think of it as the battery having a really long positive terminal that just extends to the rear of the vehicle. If nothing is drawing power from…

The confusion is that the two answer pages have two different hitches they are referring to. The #C15312 measures 2-3/4 inches from the mounting flange down to the hitch opening and the #C15313 measures 5-5/8 inches. I attached a picture that has…

The hitch you need depends on the bumper you have now on your 2005 GMC Sierra 2500. The Curt #C15312 is designed to fit if your truck has the factory cutout bumper. More than likely this is what you have on your truck. The #C15313 is designed for…

Yes, I can confirm for you that the class V Curt Trailer Hitch Receiver #C15312 is a fit for your 2006 GMC Sierra 3500. This hitch has a 2" receiver and can tow up to 16,000 lbs with a tongue weight capacity of 2,400 lbs. I have added a link to…

The only pin that should be continuously showing 12V power on the 7-Way connector on your vehicle is the 12V power circuit which is normally the black wire but not always. In 7-way wiring the 12V auxiliary power feed is carried on the contact at the…

The mounting brackets that normally hold 7-ways like the #C55416 that you referenced typically have a 2 inch center diameter like the part #PK12711U. If you were wanting to drill a hole in a surface to mount this into I'd go with a 2 inch hole…

The color of the light that the Low Profile LED Flood Light part #OPT64FR puts out is a bluish white which is very common for LEDs. For a warmer light that would work great the Omega LED RV Porch Light part #328-007-30SCPE which puts out a warmer…

If you wanted to make your 12 volt power circuit turn off when the vehicle is turned off you could install the isolation solenoid part #PK5231201 on the circuit. You'd need install the circuit to the outside posts and then for the center pin…

It sounds like you're asking about the 12V circuit on the 7-way trailer connector on the rear of your 2003 Chevrolet Trailblazer. Some vehicles will always have power and some others will not. We don't have this specific information for your…

If your trailer is working properly with other vehicles then the problem is definitely on your 2000 Chevy Silverado 1500. The fuse that you referenced I believe is for the 12V power but I could be mistaken. I tried looking up the online owner's…

A 12V trailer power circuit will typically be wired with 12-gauge wire, part #12-1-1, but certainly there is no harm in using heavier 10-gauge wire #10-1-1. If one tow vehicle is longer than another, our installers may opt to use the heavier gauge…

The Battery Isolation Solenoid #PK5231201 that you referenced can be used to charge a battery if needed. Normally this solenoid is used to allow you to allow a circuit to only be active when the vehicle's key is turned on. Basically you wire up…
