Hitch-Wired To A ‘T’

Dec 16, 2011

When you think of hitches, most likely you think of a hitch for a truck or SUV. But smaller vehicles, cars, also tow trailers behind them. Even sports cars might tow a motorcycle or camper unit. Even a car like a fiery-red Camaro.

T-connector wiring harnesses prove to be great answers for a variety of cars. Here, Cequent Group, Plymouth, Mich., demonstrates how to install a T-connector in a Camaro. And although for the purposes of this demonstration Cequent employs its branded product, other manufacturers offer similar systems; and for that reason it’s always advisable that depending on the brand of T-connector used you contact your supplier with installation questions or product queries.

The tools needed  for this  include the following: trim panel remover; 10mm socket and ratchet or 10mm wrench; 1/4″ socket; Philips head screwdriver; test-probe

>>Step 1:
Open the trunk. Locate the wiring inside the vehicle’s rear cargo area by partially removing the plastic threshold cover and felt trunk liner, floor covering and spare tire. This also will allow access to the vehicle’s battery.

>>Step 2:
On both sides, above taillight lens, remove protective cover.

>>Step 3:
Locate the vehicle’s wiring harness behind the protective cover. The taillight wiring harness will have a connection point, on both sides, matching the ends of the T-Connector.

>>Step 4:
Separate this connector being careful not to break the locking tabs. All connector surfaces should be clean and free of dirt.

 >>Step 5:  
Locate the grommet in between the taillight pocket and trunk. On both the driver’s and passenger’s sides, pull the vehicle taillight wire harness and unseat the grommet.

>>Step 6:
On both the driver’s and passenger’s side, slit the grommet to allow for T-Connector’s wiring.

>>Step 7:
From inside the trunk, route the T-Connector with yellow and brown wires through the grommet on the driver’s side. Insert the T-Connector between the vehicle connectors. Note: Be careful not to damage the locking tabs and be sure that connectors are fully inserted with locking tabs in place.

 >>Step 8:
Route the harness containing the green wire to the driver’s side. Repeat Step 6 for the passenger’s side using the T-Connector containing the green wire.

>>Step 9:
On both sides, carefully place the T-Connector’s wire inside the grommet’s slit. Reseat grommet. Add silicone rubber (not provided) to seal grommet.

>>Step 10:
Locate a suitable grounding point near the connector, such as the vehicle’s frame or cross member. (Note: Do not drill into vehicle floor. Do not drill into any exposed surfaces.) Clean dirt and rustproofing from area. Drill a 3/32″ hole and secure white wire using eyelet and screw provided.

Caution: Verify what is behind any surface prior to drilling to avoid damage to the vehicle and/or personal injury. Do not drill into any exposed surfaces.

>>Step 11:  
If not removed, remove the fuse from the supplied fuse holder. Route the red fuse holder to the Positive (+) battery post and attach.

>>Step 12:
Reconnect the vehicle’s Negative (-) battery cable and install the 10-amp fuse into the fuse holder from Step 10.

Warning: All connections must be complete for the T-Connector to function properly. Test and verify installation with a test light or trailer once installed. For initial test, reset vehicle electrical system by temporarily removing the key from the ignition.

>>Step 13:
Mount the T-Connector black box using double-sided tape (provided).

>>Step 14:
Reinstall felt trunk liner, threshold and other items removed during installation, being careful not to pinch or cut the wires.

Note: Store 4-Flat in trunk area when not in use.
