Anyone tell me what these two ports are for on a Aurora 3000?

Compressor speed sensor and the threads to attach.

So if I were to put one on a 01 I would just have to plug them?

Are they completely drilled?  Most arent and if you want to use it you drill it out.

It was never installed so I’m not sure....guy bought it and changed his mind but he said he never even opened the box so maybe not then....thanks for the info I’ll make sure I look at it first...

 

It's prob not drilled out.
