Edge states that the Edge Gas Evolution CTS3 Performance Tuner # EP39YR will add about 13hp and 18ft-lbs torque on a Silverado with the 5.3 V8 such as your 2004 model; keep in mind this will vary depending on application and other modifications. It does have a tow mode which allows for different shift points for more effective pulling. I think this is a great route for aiding your truck in pulling, however, I don't think it will be as substantial of a difference compared to changing your... view full answer...
Since I don't know for sure what light assemblies you have I can only really venture a guess on what the wire colors represent. Especially since there are so many of them. Typically white is ground so I'd start by connecting that to a ground and then test the other wires by having them contact a 12 volt power source to see what functions they activate. Red is probably stoplight circuit, brown is taillight, and yellow is probably blinker but again you'll have to test by function to determine... view full answer...
You can convert your trailer connector and mount the Battery Isolation Solenoid # PK5231201 downstream from the plug. One place the ignition power post could be connected to is your trailer's running lights. If you tie in the ignition switched power post into the running lights, then your running lights will need to be on for your battery to charge. I called Tow Ready to double check, and they verified there would be no issue to mount the solenoid on the trailer and tie into the running... view full answer...

When GM began manufacturing the New Body Style in 2007, they eliminated the need for a wiring adapter harness (until the 2014 model year, when they went back to using a harness). The tow package wiring harness is bundled up under the dash, and terminates in blunt cut wires. The harness will typically have a white tag attached to it, which would be located directly above the junction box in your photo. (It just missed appearing in your photo.) You'll simply wire the # 90195 P3 brake controller... view full answer...

In order to make lifting the spring bars up using the lift tool and bracket raising both the trailer and truck using the trailer jack will make it easier. How much to raise it depends on how difficult it is for you to lift the spring bars. Start by only raising them a little and go up a little more each time until you get to a reasonable point that you can lift the bars. view full answer...
You have 3 of the 5 correctly identified. Use a circuit tester, like part # PTW2993 to verify, but the orange wire is for the stop light switch. This wire should show current only when the brake is applied. The last wire is for an illumination circuit and is not used. Just cap it off. view full answer...

The crossbar spread will vary depending on the accessory you want to put on the roof rack.
The Yakima FrontLoader Wheel Mount Bike Carrier, part # Y02103 will work with a crossbar spread between 16 and 48 inches, so you can see it will work with most roof racks.
Most kayak carriers, like part # TH834 require at least 24 inches crossbar spread. I recommend making sure you have at least the 24 inches for a spread but I would probably place them about 28 inches apart. Again, I recommend... view full answer...
There are a couple of ways to adjust the position of tailgate # VGM-07-4000 for a better fit. First, the latches on either side of the tailgate have a minimal adjustment range of 1/32 inches. This is to fit around the striker bolt that goes into the latch on the truck.
To make a larger adjustment you would have to move the striker bolt on the truck to the designed position. The latch can be moved by loosening the latches moving and re-tightening. The striker bolt on the other hand could... view full answer...
There is a dedicated brake light only wire located up under the dash and to the left of the steering column on your 2009 Chevy Silverado. It is with a wire bundle held together with a white tag. There should be an orange or light blue wire that is the center high mount stop lamp wire (CHMSL) that you could use. It is there on your truck whether it has a brake controller or not.
You would need to attach wire to the end of it, route it through the firewall, under the truck, and over to where... view full answer...
There is no problem installing a fifth wheel hitch if you have a spray-on bed liner as long as the bed liner is fully cured. If you are looking into adding a spray-on bed liner to your truck, then you will want to check with the installer regarding cure time and make sure it has fully cured before you install a fifth wheel hitch or bed rails.
We do not recommend installing a fifth wheel hitch on plastic bed liners because it will crush the bed liner when under a load and a plastic bed... view full answer...

Next to the fuse block under the hood, you'll find a red wire with a ring terminal on the end of it. This wire provides power for the brake controller, and installs on the power stud on the side of the fuse box. Use the stud closest to the firewall. The power stud is activated by... view full answer...

You want the illumination circuit. If you look under the dash with the other tow-package wires. There should be an orange wire. You can test this wire with a circuit tester # PTW2993 if needed... view full answer...
