Vems raw-52 install

[Big simer]

I have a 84 rx7 gslse n want to watch my afr’s so I purchased the product . Was told by a friend I need to always be aware of my afr’s . My car comes with a 1 wire o2 sensor . I understand most of the wiring to the o2 but the other 2 wires from the gauge I’m alil unsure of . The one with the fuse (red) goes to constant battery or to ignition power? Now to the blue wire where does this one go? I’ve never installed a wideband before so I need all the help I can get. I was also told to wire in a relay to power, what’s ur thoughts?

The blue is ground
the fused goes to a switched 12v source.

Didn´t you get the paperwork in your box which details all of this?
