Simple 02 Sensor And Boost Gauge Questions

[r32rb20detgtstQLD]

hey r there ne guides on here how 2 stick an 02 sensor in, ive just bought one but ive got no idea how to stick it in so im paying a mechanic to do it for me. the problem is this is gonna cost about 85bux - but it looks like a really simple job so if it is simple maybe i should do it. then again i have no mechanical knowledge so maybe not.. but yeh are there any guides on here how 2 do it.

Also boost gauges, Ive just bought one and now it seems im gonna have 2 drill a hole through my dash or sumthing and the firewall... do you actually have 2 do this or is there an easier way.. I was thinking since there is a factory boost gauge i can rip it out then connect my one to it or something..

thanks guys

I did my O2 sensor on the weekend and I'm not really mechanically minded at all. If you've got a nissan replacement one than it'd be easy as. Mine came with no plug, had to re-wire mine into the wires from the old O2 sensors plug which wasn't overly hard.. took about an hour or so.
