I second the relays. Without relays for each headlight there is in my opinion too much voltage drop for halogen bulbs to work as they should. I had a motorhome with H-4 halogen bulbs and relays made a big difference.

I am just reading about relays now.....so will do that first and perhaps that in itself will make a big difference.....are all of the relay kits pretty much the same ? Thanks.

The difference is dramatic with relays. With relays you are simply powering the lamps much closer to the power source. Eliminating that long (and old) body feed harness run from the horn relay into the car, through the headlight switch, across the high/low floor switch and back out to the lamps. The old wires out to the lamps now become the relay triggers.

Basically, on the B Body, find the high beam and low beam feed in the forward harness up along and under the left fender. 70 should be Green for high beam, tan for low.

Cut through both wires and add a Bosch style relay into each circuit. Feed the relays from the horn relay buss, and make sure to clean up your grounds.

I thought T3 referred to the size of the headlghts......so was not aware that would cause confusion. The outer headlights are halogen and the inner high beam headlights are just std sealed beam.

Funny, I have the original T3s in my 67 Toronado, They work great.
