The brake light circuit is split between two lights (the same the parking lights and hazard flashers). The power leads for the hazard and parking lights come through the tunnel from the forward power cells. At the rear end of the tunnel, these leads split to the right and left. I have a wire loom conduit running along the rear splash guards. The split is located next to the parking brake cable box.

This Is the conduit coming from the tunnel into the engine bay. I ran the hazard and parking light circuits through this. There was no need to run the brake circuit through this conduit, because the brake light switch is wired to the ISIS Master Cell. The signal will be transmitted to through the data bus. This is another instance where ISIS saves you time and effort.

The brake circuit is assigned to Power Cell #2. This is the power cell located in the rear engine bay. I routed the power lead for the brake lights to the same area and spliced the power lead to wires running though the same conduits the parking and hazard circuits.

The hazard lights (yellow), parking lights (green) and brake lights (red). The Hazard and parking circuits come from the front of the car. The brake circuit comes from Power Cell 2, which is mounted on the passenger side of the engine bay. I just ran the brake circuit down the wire loom to get tot he other light. I am glad I did, because the transaxle bracket can be a bear to get back on the car when the body shell is mounted.

The brakes are activated by the brake light switch under the steering column. The switch is wired to the corresponding signal wire from the master cell.

The brake line circuit gets wired together using a terminal block. Once I know everything works I will use Goop to seal up everything.

From a maintenance perspective, all tail light circuits are connected to the power leads with Weather Pack connectors. The reason for this is if the body shell has to come off, the rear lights can be disconnected from the power system.

I ran two legs of wire loom for all the circuits going to the lights. I run them under the cross member at the point where the engine bay begins and the tunnel ends.
