TF trucks had
park lights, NOT "running lights" [always on], but there's a simple tech tip to rig it that way if you want
park lights only were standard for TF trucks, turn sigs an optional add on
from 55 on, which included park lamps for 2 pin bulbs - see an accessory install
instruction here, full wiring diagram a few pages further along
that switch is nothing like original [
wiring shown here], which should be available from most repro suppliers and will have the park light terminal - but you do need the 2 pin socket in the lights, and a replacement socket should be available at a FLAPS
