i need help-Installing aftermarket gauges
 

I drive a 91 s10 blazer 4dr 2wd 4.3 v6 tbi.


I bought this as a project. None of the gauges work except the battery voltage and gas gauge...id like to get my tach,speedometer,oil pressure etc working.I'm basically a idiot when it comes to electrical and cars.So any help on installing is greatly appreciated.thank you.

Main key is where are the senders etc for each gauge,i know the speedo is on the transmission correct? How do i run power to them as well
