1994 GMC Questions and Answers

• 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 connect

• Maximum Trailer Weight 1994 GMC Suburban and 1997 Dodge Ram are Capable to Towing
  
• At first glance, that trailer might be too much for either vehicle to handle. Since the towing capacity of a truck can vary greatly according to how it is equipped, to determine how much either vehicle can tow you will need to do some calculations. It is entirely possible that the capacity of the hitch installed on either vehicle is actually rated higher than the vehicle tow rating. You will need to abide by whichever rating is lower. The GCWR, or Gross Combined Weight Rating should be lis

• Can a Hopkins Agility Brake Controller be Installed on a 1994 GMC Sonoma
  
• Brake controllers are not vehicle specific and can be installed in most any vehicle with proper wiring. I also attached installation instructions for the Hopkins Agility Brake Controller # HM47294 for you to check out also. The first thing you are going to need to install this product is a 4-way present at the rear of your vehicle. If you do not have one you will need a Tow Ready Custom Fit Vehicle Wiring # 118312. (installation instructions and installation video attached) Once a 4-way is

• 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 directi

• 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. Once the 4-Way is installed, see instructions link, you will need the Brake Controller Installation Kit, # ETBC7, and a brake controller. I recommend the P3 Brake Controller, # 90195, which is one of the best controllers we carry. We have detailed instructions for installation of the controller and the wiring kit, see links, and we have installtion videos of a brake controller and wiring on a 1

• Brake Controller Wiring on a 1994 GMC Safari
  
• The best bet would be to locate the stoplight switch at the top of the brake pedal, and then locate the wires or wiring harness that comes from it. Using a circuit tester, like part # 40376, probe the wires until you find one that shows a signal only when the brake pedal is applied.
