Look through the list of wiring diagram descriptions below to see if you can find the diagram you need to wire your layout. If you still are unable to find an exact match to the controls and tracks you are using click Wiring Principles for directions on wiring layouts in general.

    Since the mid-seventies all slot car sets were produced with plug in contollers and transformers, wiring diagrams are not provided for plug in style terminal tracks.

General Wiring Principles

    These directions apply to only the standard controllers connected to a single transformer.  Shared Lanes, Team racing and other non standard wiring techniques are not covered here.

    It is important to note that Common Ground Terminal tracks do NOT allow Reversing Controllers to be used on the layout.

    So the first question is does your layout have a Common Ground or an Isolated Ground Terminal track.

    To determine if your Terminal track has a Common Ground or an Isolated Ground, you can count the number of screws or look at the bottom of the terminal track.   If the track has three screws or two of the rails share a terminal connection it is a Common Ground Terminal track.  If there are four screws you still need to check the bottom of the track to see if two of the rails share a terminal connection.  If the track has four screws and each screw connects to a different rail then it is an Isolated Ground Terminal track.

Common Ground Terminal Track
(Reversing Controllers NOT allowed).

    If your layout has a Common Ground Terminal track then the screw that connects to two rails is wired directly to the transformer.  One wire from each controller conects to the other screw on the transformer.  The remaining wire from each controller connects to each of the remaining screws on the terminal track.
    You can change the direction of travel for both cars by swapping the wires attached to the transformer.
    Do NOT change the wires on the terminal track.

Isolated Ground Terminal Track
(Reversing Controllers Optional).

    If your layout has an Isolated Ground Terminal track then two of the Terminal track screws are used for each lane.  If unsure which two are for each lane look at the bottom of the track and find which pair of screws are used for each lane.

Using Non-Reversing Controllers

    If you are using non-reversing controllers then one terminal track screw is wired directly to the transformer, the other terminal track screw connects one wire from a controller, the other wire from the controller connects to the other screw on the transformer.
    You can change the direction of travel for BOTH cars by swapping the wires attached to the transformer.
    You can change the direction of travel for ONE cars by swapping the wires for one lane attached to the transformer or swapping the wires for one lane on the terminal track.   Driving in opposite directions can be very dangerous for cars that fishtail on curves.   Meeting on a squeeze track or lane change track causes a head-on collision.

Using Reversing Controllers

    If you are using reversing controllers there are four wires per controller, Two input, and Two output.  The Two Inputs from both controllers connect to the transformer and the Two Outputs wires from one controller are connected to two of the screws on the terminal track that connect to the same lane rails.  The other controller is connected to the remaining two screws on the terminal track.
