The truck is still running amazingly well. Im thinking about wiring the aux lights to the high beams instead of an independent switch. Does anyone have experience doing this with a t100? Any advice?
Not on the T100, but this should work equally well for the T100 as the 80. On my T100 I just used a generic toyota light switch to drive a relay for the hellas. On the 80, I got ambitious a few years back and decided to re-purpose a rear heater switch. The rear heater switch has two settings and a center off position. This gives me an option to turn on the driving lights independently via the left position and links them to the high beams via the right position. This is where it gets a little weird. Toyota used a switched ground for the heater switch so if you want the LED indicators in the switch to work (green for high beam connection and orange for "On") you'll have to wire things a little backwards. If need be, I can draw up a diagram but the long and short of it is to run two relays with main power coming straight from the battery to the relay and then output power to the lights. Then run signal power for the orange side(I used an ignition switched source but you can use standard battery power if you want.) I wanted to make sure the lights couldn't work without the ignition on...YMMV. Then run the relay ground to the heater switch. Now run the signal power for the green side from the high beam wire for the headlights--you can tap into the high beam headlight relay here if you prefer that to a vampire connector. Then run the relay ground to the green side of the heater switch. The switch will need the two ground wires from the relays and a ground wire for the switch itself. It will also need a power source for the internal illumination bulb--best to tap into an adjacent switch so that it will dim with the dim controls.
This may be able to be accomplished with one relay, but it will need to have an extra couple connectors to keep things from backfeeding. I had the standard relays laying around so I used them. Take a look at the 80 series forum for instructions on re-labeling the switch.

Also. As I have thought more about this, I seem to remember an issue with tapping into the dash dimmer circuit. It may be another switched ground type thing where the ground for the back light goes through the dimmer control but I am not sure. If need be I can take a look at my wiring and give a positive answer.
Trucks look great, those headlights look like crap I got a buffing kit years ago and buffed mine up, used some finer buffing/cutting compound to really make em glossy. The kit was some scotchbrite looking discs with a cutting compound in them, you just got them wet and went after it with a drill. It worked great. When I was done I got some extra thick 3M paint protector sheet and put over them when I did front end of the hood and fenders with the same stuff, just a thinner mil.
My lights held up great after that, they had some fine crystaline cracks deep in the plastic, but the haze never returned. Sadly both housings were destroyed enough after I hit a deer years ago, that I had to replace them with some ebay aftermarkets. The Toyota ones were just too crazy expensive to justify. They have been good haze wise so far, but the light pattern sucks compared to the OEM lenses. I went from loving the headlights in my T100, to really disliking the light distribution.
