TBI- Fan Switch.
So I know the fan switch on TBI cars on the passenger side head turns on at like 230. Anyhow I have an aftermarket adjustable fan switch so do I even need the old OEM one? Does it serve any other purposes?

It's only a switch to ground, it does nothing else

All it does now is plug the hole, still an important thing to do
