How to Hook Up a Throttle Cable
Throttle linkages are made in three basic configurations. Mechanical, or "bell-crank," systems are among the oldest and utilize system of levers and rods to link the gas pedal to the throttle. Cable systems that rely on a metal cable sliding within a flexible sleeve have largely replaced bell-crank mechanisms, which have always been prone to squeaks, rattles and hanging up. Electronic "drive-by-wire" throttles are gaining a foothold in the automotive industry but have yet to supplant the reliable cable. You can install a throttle cable in your driveway or garage.
Instructions
- 1
Crawl under the dashboard and locate the hole in the firewall through which your throttle cable will pass. Its typically located just above the gas pedal. Grasp the engine-end of the throttle cable and push it through the hole into the engine compartment, and continue feeding it through until the mounting flange on the sleeve hits the firewall.
2Install the bolts that retain the sleeve mount to the firewall and hand-tighten them. Open the hood and reach into the engine bay to pull the cable up; lay it on top of the engine but do not connect it yet. Go back inside the car and pull the end of the cable over the forked split in the top of your gas pedal. Tighten the nut to clamp the cable to the gas pedal. Pull the pedal all the way up.
3Install the engine-end of the throttle cable into the lever arm on your carburetor or throttle body. The procedure will vary by the type of engine. Some cables have a cylindrical piece on the end that locks into a slot in the throttle lever. For these types, pull the throttle lever all the way back, insert the cylinder into the recess on the side of the lever and feed the cable through the slot. If your throttle uses a retainer, push the throttle tip into the appropriate hole on the lever arm, then slide the retainer into the groove on the throttle tip to hold it in place.
4Push the retainer on the end of the sleeve down into the retaining fork on the throttle cable bracket. Some applications have provisions for adjustment. If so, turn the adjuster nut on the sleeve until the cable is taut but not pulling on the throttle arm. Other applications dont use a forked throttle bracket; in these cases, feed the throttle cable through the hole in the bracket before connecting it to the throttle. Adjust the cable afterward.

How to Hook Up a Tow Dolly Lights to a Car
Whether you need to tow your car to the local car repair shop or behind your RV while driving across the county, you will need to buy or rent a tow dolly. A tow dolly is the safe and legal way to tow your car. It has a single axle with a tongue, similar to the letter T. The tongue will hook to the towing package on the back of the vehicle which will tow the car. The towing package consists of a hitch and wiring harness installed on the back of your vehicle, and the wiring to control the lights on the tow dolly hooks into the wiring harness of the vehicle itself.
Instructions
- 1
Loosen the coupler latch on the tongue of the tow dolly and place the coupler over the 2-inch ball of the hitch on the vehicle which will be towing the dolly. Push the towing dolly back and forth a bit to ensure the coupler is seated properly on the 2-inch ball.
2Push down on the latch to close the coupler latch over the 2-inch ball and place the pin through the latch to securely lock the tow dolly onto the hitch. Pull up on the towing dolly to test if it is secured. If the coupler seems loose on the ball, adjust the coupler, using a wrench.
3Connect the wiring plug of the tow dolly to the plug beside the hitch. If the wires do not have a plug, then connect the color coded wires of the dolly to the corresponding wires of the towing package. The yellow wire controls the left blinker, the green wire controls the right blinker, the brown wire controls the tail lights, the white wire is the ground and the red wire is for optional brakes on the dolly.
4Attach the safety chains to hitch. Crisscross the chains, allowing slack in the chains for moving around corners.

How to Hook Up an Alternator to a Battery
Regardless of the type of vehicle you drive, the alternator is one of the most important components in the engine. It acts as a generator to keep the battery charged while the engine is running, and controls the flow of electricity to the various electrical components of the engine. Over time, the alternator can suffer damage from wear and tear, and you many need to install a new one in order to keep your vehicle running properly.
Instructions
- 1
Park the vehicle on a flat surface and shut off the engine. Set the parking brake. Allow the engine to completely cool (30 minutes to an hour) and open the hood. Refer to the belt diagram on the underside of the hood or the radiator shroud cover to locate the exact installation area for the new alternator. Disconnect the negative battery connector with a wrench or socket.
2Disconnect all of the wires to the old alternator. Follow the instructions on the diagram chart to locate and loosen the serpentine belt tensioner pulley that holds the belt tight in place, as this same belt attaches to the alternator. Use the socket and ratchet to loosen the tensioner pulley and slide the belt off. Take the now slack belt and remove it from the alternator. Loosen the bolts holding the mounting bracket for the alternator with a socket or wrench and remove the old alternator.
3Install the new alternator. Mount it in place of the old alternator and replace the mounting brackets. Tighten the bolts in place with a socket or wrench. Reattach the wiring to the new alternator, but save the positive and negative connections for later. Slide the serpentine belt over the alternator pulley and adjust the tensioner pulley to slide the belt back in place over it. Adjust the tension on the belt until it is tight.
4Connect the positive and negative connectors from the alternator to the battery of the car. Reattach the negative battery lead. Remove all of your tools from the engine and close the hood. Start the car and allow it to run for several minutes to ensure the belt and alternator are installed correctly.

How to Hook Two Batteries Together
The car battery is recharged by the alternator of your car so that it can continually supply electricity. Hooking two batteries together can be done without much effort. It is a simple process that will take only a few minutes. You may want to connect two batteries to have a longer charge build-up or for another project needing battery power to last longer between charges.
Instructions
- 1
Find a safe place to work and put on gloves and protective goggles.
2Lay out connector cables so they are easy to access.
3Connect the batteries by attaching the negative side of the first battery to the positive side of the second battery using your cable. Tighten the retaining nuts on the cable clamps with pliers.
4Hook the positive side of one battery and the negative side of the other battery to your power need. Tighten the retaining nuts on the cable clamps with pliers.
