  • Does Firestone Ride-Rite F2101 Fit The 1994 GMC Suburban 2500?
  • Hey Jeff, thanks for reaching out. You asked a good question so I went ahead and ran it by my contact at Firestone. They said the # F2101 kit will fit both the 1500 and 2500 models of the 1994 Suburban. Older catalogues show fitment on the 2500 Suburbans with the same kit. They did admit their Firestone page needs to be updated, so it turns out the info on our site is correct! Thanks for bringing that to our attention. Feel free to reach out and reply below if you need anything else.

  • Will the Derale Transmission Pan Cooler D14204 Fit a 1994 GMC Suburban K1500 With 4L60 Transmission
  • So long as you have 2" of space beneath your factory transmission pan then yes, the Derale Transmission Pan Cooler part # D14204 will fit your 1994 GMC Suburban K1500 with the 4L60 transmission. In regards to the transmission fluid filter, you can use the OEM style that is for your transmission but Derale does not offer transmission fluid filters. The note for using a smaller transmission fluid filter only applies to models after 1996. Please note we have a temperature sensor this pan...

  • BK LED on Curt 7-Way Adapter, Part # C57674, Remains Lit Even Without a Trailer Connected
  • If you do not have a proportional brake controller (but instead have a time-delay type) the LED being lit could indicate a short to the controller output circuit. In some cases the manual brake switch on your controller may be partly engaged; this would also cause a signal to be sent to the 7-way BK LED. You can correct this by flipping the manual switch on and off several times to clean the contacts. If you are using a proportional type brake controller such as the Prodigy P2, part #...

  • 7-Way Wiring and Brake Controller for 1999 GMC Suburban
  • Hi Lamont; if you already have a 4-way on your 1999 Suburban you can upgrade to a 7-way using the # ETBC7 you were looking at. If you don't have a 4-way, you will also need the Curt T-Connector Vehicle Wiring Harness # C55319. Once you have your wiring installed you will be able to add a brake controller like the Tekonsha Primus IQ # TK90160. This is a budget friendly option that still has a lot of nice features and is proportional. What kind of trailer will you be towing?

This measures 64-1/2" long x 37" wide x 4" tall so it's got the length and height you are wanting.

  • Brake Controller Install Procedure for 1998 GMC/Chevy Suburban K2500
  • GM didn't start prewiring the Suburban until the 2000 model year. To install a brake controller like the Tekonsha # TK90160 Primus, you'll need to hardwire the controller into place. As a starting point, you'll need to have a functional 4-pole trailer connector. The # C55319 would be the easiest way to install one. Once that's in place, you'll use our brake controller install kit, part # ETBC7. The kit includes the adapter that will convert the 4 pole provided by the # 118319 into a 7-way,...

  • Ways To Convert A 5 Way Boat Trailer Plug To 7 Way
  • The blue wire on a 5 way plug can be used for reverse lockout function (on surge brakes), or can be used for electric brake signal depending on how your specific trailer is wired. Most 7 pole to 5 pole adapters are wired for the reverse lockout function for surge brakes, not for electric brake signal. So if your trailer is setup with surge brakes (which yours probably is, being a boat trailer) you could go with the 7 Pole to 5 Pole Flat Adapter # A75TB. You would not need a brake controller...

  • 7-Way Trailer Wiring Connector Recommendation for 1996 Chevy Suburban
  • To install a 7-way on your 1996 GMC Suburban you'll need to first install a 4-way like part # 41125 to give you the taillight circuits. Then to convert to a 7-way all you need to do is plug this 4-way into the # 37185 and you'll have a 7-way with the taillight circuits active. If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes with everything needed to wire up the 7-way and install a brake controller. For a brake controller...

  • Is Junction Box Recommended When Installing New Trailer Wiring 7-Way
  • Using a junction box makes installing new 7-way wiring much easier. Often times, people will run the wires from a 7-way such as yours to a junction box like part # 38656. From there, they will run the standard wire colors to the trailer lights, brakes and battery. I have attached a photo that shows how this setup works in the junction box. Most molded 7-way pigtails will come wired with the RV style color code. If you ever need to replace your 7-way connector in the future, you could simply...

  • Troubleshooting Trailer Braking System With Brake Controller Indicating OL or Overload Error Code
  • The OL or overload error code indicates a short in the brake output circuit. As a first step, you will want to see if the problem exists with the wiring on the trailer or on the vehicle. Due to its intermittent nature, I'm suspecting a loose connection or a worn wire in the brake controller's output circuit. Try unplugging the trailer and activating the manual brake switch on the controller. If you get the error code at that point, it is a pretty good indication that the problem exists...

  • Troubleshooting an Integrated Brake Controller in a 2016 GMC 3500 with a BrakeRite Adapter
  • You have the Dexter BrakeRite SD Adapter for Ford/Chevy Integral Brake Controllers # T4845900 which is not the correct adapter.

You can also check to see if your truck has a hydraulic brake setting for the integrated brake controller, sometimes there is a hydraulic setting that needs to...

  • When to Use a 20 amp or 30 amp Circuit Breaker When Installing Brake Controller
  • It really depends on the amount brake axles your trailer has. If you have up to 2 brake axles the 20 amp breaker is recommended but if you have more than that you'd need the 30 amp one.
