1981 Rx7 turn signal flasher part #P30213
The turn signal flasher is the device called the Control Processing Unit. It bolts up under the dash by the fusebox.
What it looks like outside its case.

The poor solder connections that were the cause of the issues on my '81.

A simple flasher was not good enough for Mazda, the turn and hazards are controlled by a module that uses a relay and some timer circuitry. I expect this is so that they flash the same speed no matter how much load is or isn't on the circuit.
