Is this a trick question?
It would have no effect because I'd have already replaced it with
silver-impregnated, oxygen-free copper wire with thick Teflon insulation, in
one wire gauge larger than stock, and I'd be using relays on the horn and
lights.
I've only run into problems at the connectors, unless the wire had been
crimped or abused by the DPO.
