The brake control harness connects to a black electrical junction box located under the dash, to the left of the steering column. The vehicle connection point is in the top row of the junction box, second from the left. Remove the box cover to access it.
1. Locate the black electrical junction box under the dash, left of the steering column. Remove the cover and find the connection point in the top row, second from the left. 2. Insert the CURT brake control harness connector into this vehicle connection point. 3. Verify battery power (+) using a circuit tester by carefully probing the connector. Make sure no wires are touching. 4. If power is present, skip to step 4 in the manual. If no power, install universal brake control wiring kit #51500 following its instructions. 5. Insert the brake control harness black connector into the brake control's quick plug connector. 6. Secure the harness with provided cable ties, avoiding pinch points. 7. Complete installation using the brake control unit instruction manual and perform test procedures.
Not necessarily. After inserting the CURT brake control harness connector into the vehicle junction box, verify battery power (+) using a circuit tester. If power is supplied to the connector, you can proceed without the wiring kit. If the vehicle does not supply power to the connector, you must install universal brake control wiring kit #51500 and follow its installation instructions.
After inserting the CURT brake control harness connector into the vehicle connection point in the junction box, carefully probe the connector with a circuit tester to verify battery power (+) is supplied. Make sure none of the wires are touching during this test. If power is detected, proceed with the installation. If no power is detected, you will need to install universal brake control wiring kit #51500.
If your vehicle does not supply power to the brake control harness connector, you must install universal brake control wiring kit #51500. Follow the installation instructions provided with that kit. To use the factory connector with the universal wiring kit, the factory harness must be modified: cut the battery wire leading to the factory connector leaving enough room to use a butt connector to attach the battery wire from the universal kit, and cut the trailer brake wire in the same manner. After installation, cap and/or tape the exposed ends of all cut wires to prevent shorting.
Wire cutting is only required if your vehicle does not supply power to the brake control harness connector and you need to install universal brake control wiring kit #51500. In that case, you must cut the battery wire and trailer brake wire leading to the factory connector, leaving enough room to use butt connectors to attach the wires from the universal kit. After cutting, cap and/or tape the exposed ends to prevent shorting. If your vehicle supplies power to the connector, no wire cutting is necessary.
When verifying battery power, carefully probe the connector with a circuit tester and make sure none of the wires are touching. If you install universal brake control wiring kit #51500 and cut wires, cap and/or tape the exposed ends of all cut wires to prevent shorting. When securing the harness with provided cable ties, avoid any pinch points. After installation, test for proper function by following the brake control unit instruction manual.
After completing the installation, test for proper function by following the brake control unit instruction manual. The manual emphasizes that all steps must be followed to ensure the CURT brake control harness will function properly, and testing is required to verify correct operation.
The CURT brake control harness (51352/51353) fits Cadillac Escalade (EXT/ESV), Chevrolet Avalanche/Silverado/Silverado Classic/Suburban/Tahoe, GMC Sierra/Sierra Classic/Yukon/Yukon Denali/Yukon XL/Yukon XL Denali, and Hummer H2. Model years are not specified in the manual—contact CURT at 1.877.287.8634 to confirm your vehicle.
Only if your vehicle does not supply power to the brake control harness connector. Test with a circuit tester after inserting the connector into the junction box. If power is present, no additional kit is needed. If not, install universal brake control wiring kit #51500 and modify the factory harness as instructed.
The manual does not specify required tools. A circuit tester is needed to verify battery power. If universal brake control wiring kit #51500 is required, refer to that kit's installation instructions for additional tool requirements.
No drilling is mentioned in the installation instructions. The harness connects to an existing junction box connector under the dash. Drilling may be required if universal brake control wiring kit #51500 is needed, but that is not specified in this manual.
Cap and/or tape the exposed ends of all cut wires to prevent shorting. This applies to the battery wire and trailer brake wire that are cut when modifying the factory harness to work with universal brake control wiring kit #51500.
