Couple of wiring questions.

[leveliv]

I bought all these new sunpro gauges...

But now I need to know where I can hook up all my positive wires..from all the gauges to..I don't want to go through the fuses cause thats a pain and I tried already.

For my temperature gauge where do I put the sensor? somewhere in the block?

for my oil PSI gauge...do I need a sensor

and finally what do I have to hook up to have my Battery Volts Gauge working?
