Although the TMAX has two headlights only one is connected to low beam. There is a simple mod to connect both lights that I picked up from an American TMAX thread. Feel up to it Tony? I rode my TMAX on a wet night on a road with poor lighting and found the 1 light low beam only just adequate. Would be really good to have both beams.

Yamaha must have thought that we
would want to have both headlights on, so the plug on the back of the
headlights have an empty socket for a female spade-type connector.
You'll want to go to Radio Shack and pick up:
1. One right-angle (90 degree) spade connectors for 12 gauge wire.
2. One wire tap
3. About 4 feet of 12 gauge wire
4. Inline fuse (just in case)
5. Electrical tape
6. Some plastic wire loom (if so desired, but not strictly necessary)
7. Soldering gun or good crimp tool.
From under the headlights, you should be able to get your hand up
behind the headlights. Start with the left headlight (the one closest
to the rear brake lever.) You'll see that only 2 of the 3 blade type
connectors are used. Using a flat-blade screwdriver, pop off the "lid"
of the connector. You'll be able to insert the 90 degree female spade
connector there. (making sure, of course, that you've cut and crimped
the 12 gauge wire to an appropriate length and attached it to the spade
connector.) Once you're satisfied, just reconnect the headlight socket
to the headlight bulb.
Next, run the wire through the wire loom and zip time to the wire
bundle. This will help give it a "factory look." Run the wires until
you get to the right-hand side of the bike. Insert an inline fuse if
you'd like (I did - 10 amp fuse is plenty.) This will help ensure that
if there's too much draw, the fuse will pop before anything bad happens
(like burnt wiring.)
Once you're ready to connect the right hand headlight, reach up and
pull off the headlight socket. Once you pull down the connector, you'll
see the low-beam wire. Tap into that wire with the wire tap. Be sure to
seal up the tap well with electical tape. Once you're satisfied, just
reconnect the headlight socket to the headlight bulb.
Before tucking the wires away, check that both headlights are on in low
and high beam mode. If all looks OK, then tuck up and zip tie the
wires. That's it
Left side three prong bulb that only has 2 wires hooked up to it
and the connector with the 2 wires.
Opened up the connector to see what you need to make the connection with that elusive third prong:
Pulled out that wire to guage the new part :
I used a standard connector that I tweaked with some needlenose pliers and it worked.
NO pic, sorry.
Then tapped into the other side:
Now it works!
