  • Complete Wiring for Lights, Electric Brakes and Controller for a 94 GMC 1/2 Ton Truck and Trailer
  • Lets start with your 1994 GMC 1/2 Ton Truck. You will need to start with the # 118315 4-Way connector.

  • 5th Airborne Air Ride Coupler Recommendation for a 2002 Alfa Sun w/ RBW 7016 Pin Box.

You will need to take a few measurements on your pin box and we will know for sure what you have. Check out the picture I attached. Your 2a measurement should be 7-1/4 inches,...

  • Troubleshooting High Transmission Temperatures after Transmission Cooler Installation
  • I would try reversing the direction of the fan on the Derale Transmission Cooler # D15960 that you have installed on your 1994 GMC Truck to see if that will yield you cooler oil temperatures. Generally speaking coolers loose from 25 to 40 percent of their cooling efficiency when the fan pushes air through the cooler as opposed to being pulled through it. Also, depending on the location of the cooler in relation to underside of your vehicle the fan might be fighting the natural airflow...

  • Fifth Wheel Hitch Recommendation that Allows at Least 18 inches of Vertical Height Adjustment
  • You would want to go with a fifth wheel hitch that has a height range that will allow your trailer to be towed level. If you need 18 inches to allow the trailer to tow level you would need to go with a taller hitch than the part # PS30094. The part # RP30869 would be a much better option that would also allow the trailer to tow level as it can go up to 19-1/4 inches in height. This hitch also has a cushioned head, a 360 degree jaw design, and a round tube slider that would operate...

  • Where Does Fifth Wheel Hitch Install in bed of 1994 GMC 2500 with 8 foot Jacket
  • In general you want to install a fifth wheel hitch either right above the rear axle center or slightly forward of it. With the rail kit that comes with the # PS30128 the rearmost rail would be mounted so that the rear of the rail is 30-15/16 inches forward of the rear edge of the bed since your truck is an 8 foot bed. The king pin center will end up being right at 1-1/2 inches forward of the rear axle center.

You can use your circuit tester on this pin to confirm that it carries a signal ONLY when the brake pedal is pressed (and not when other vehicle functions are activated). I have...

  • Trailer Wiring Harness for a 1994 GMC C/K Series Pickup Truck
  • In 1994 the Sierra was just a trim level of the C/K series GM trucks. It wasn't until 1999 that the Sierra started to take the place of the C or K designation and that transition was complete in 2000. For a trailer wiring harness that will fit your truck I recommend the Tow Ready harness # 118315. It plugs in line with the vehicle tail light wiring. I have linked a video showing an example installation for you. A mounting bracket such as # 18144 is also recommended.

  • Finding the Correct Brake Switch Wire on a 1994 GMC C/K Series Truck to Install a Brake Controller
  • What you will want to do is test each of those wires with the headlights and turn signals on, one at a time. If one of the wires shows power with the headlights or turn signals on then it is not the correct wire. You need the one that is hot only with the brake pressed and not with the headlights or turn signals on. In the event that neither of those wires is correct and you cannot find one that is at the brake switch, then you can find the stop light or CHMSL fuse and tap into it to...
