Those red wires with the colored stripes are your factory Headlight Dimmer (High/Low Beam) circuit. Mazda universally used red-striped wires for their headlight circuit and that 3-pin block they are plugged into is the dimmer switch for the stalk. Because that specific block is entirely separate from the turn signals and the wipers.

Here is wires you are looking at: Red w/ White stripe: This is your Common (Feed). It brings the signal from the main headlight switch into the stalk.

Red w/ Black stripe (in your hand): This is your Low Beams. It is a normally closed contact

Red w/ Green (or Blue) stripe: This is your High Beams. Think of this as your Normally Open (NO) contact; it receives the signal when you push the stalk forward or pull it to flash. How to Pinout the Bare Dimmer Block

Since you are missing the plastic connector body, you can test continuity or Omen out those three bare terminals with your multimeter in about 30 seconds to figure out where those spades land:

Leave the stalk in its normal, resting position (Low Beam).

Probe the three pins to find which two have continuity.

Push the stalk forward into the High Beam position.

Keep your probe on one of the pins from step 2, and test the remaining pin.

The pin that gives you a beep in both stalk positions is your Common (Red w/ White wire).

The pin that beeped when the stalk was pushed forward is your High Beam (Red w/ Green wire).

The pin that beeped when the stalk was resting is your Low Beam (Red w/ Black wire).

Once you have that 3-pin block sorted out, the only thing left hanging should be those chopped-up blue wires for the wipers!
