The only Heljan locos that require any lighting resistors are the original first release class 37 and 47, which were fitted with filament bulbs. Every other loco since those, (to our knowledge) have been fitted with led’s, which have their own resistors built into the circuitry. That’s on the lighting board, not the discarded DCC PCB board. So no resistors are required in either the common V+ feed or the switch feed. Any brightness adjustments are done electronically via the usual CV settings.  If you are uncertain of the age of the model fitting a resistance to V+ will do no harm.
