wideband wiring

i posted this in tuning section, not realizing id likely not get much of an answer so im moving my post here.

i can see how this job is pretty streight forward. however, this will be the first time ive ever ran this type of wiring. the bung weld and location ive got picked out correctly. my only concern is the consequences i will have if i route these wires through iffy spots. most videos i come accross they go from the sensor location up and to the firewal, then through the air vent.

if it is through an air vent, would i have any issues if i ran my heat? i just don't see that as the best choice. But i can't find many other videos that are tutorial based that go any different route.

should i get any wire harness type clips to keep it hugged up and away from heat sources?

what model vehicle?
