I just purchased reverse indiglow gauge pods. one is voltage and the other is oil pressure. i have reverse indiglow gauges installed but the cost to hookup the pods is a little high. can anyone tell me if its possible to hookup the pods on my own. i am familiar with electronics and hooking up stuff but i'm not sure how to go at doing this... i have wires running from my battery that used to plug into my r1 tachometer before it broke, i think there are two wires...can i use these for the voltage? also how would i go about hooking up the oil pressure gauge? which wires on the interior can i toggle it to or do i have to send it through the firewall and toggle it to my thermostat or something? thanks for any help, i do appreciate it!
