i have a 96 hatch and i have a volts gauge, an air/fuel ratio gauge, and a tach to put in. i had em all in at one point but it was a sloppy *** wiring job. so i decided that i wanna be a little smarter and have it all hooked up to the stock cluster (speedo, gas, temp, etc) i wanna splice into the power and ground and at least power em up that way but im not too sure what wires to splice into. does anyone know right off hand? and is it safe to wire a volts, air/fuel ratio, and tach up to the oem gauge cluster? that wont draw tons more power and f up my **** would it? thanks in advance

ps: i have a streetwires power/ground distribution block with 2- 6 gauge 39" battery terminal cables and 1- 10 amp fuse for $80 if anyone is interested.
