Well i got my new lifters and pushrods, there soaking in oil, amnd will continue to soak, for a coupe of days lol. well any way, i bought 3 gauges at the same time. Water temp, oil pressure, and an a/f ratio. I got them on the pillar, all hooked up to each other(grounds, power,0 except the power for the a/f one since it needs to be connected to the key. My question is the a/f gauge has a purple wire that connects to the o2 siganl wire that connest to the pcm. were would that wire be? and what color, the temp and oil look so easy to connect, i cant beleive i wanted someone to install them!!!!!!!!!

o2 signal wires (ho2s) run from the pcm to the o2 sensors the ho2s left sensor signal wire is red/black and the ho2s right sensor signal wire is gray/light blue....
If you got the tinted ones on eBay let me know how good you can see them in the day, Im thinking about getting some.
the purple wire on the gauge connects to Pin number 43 at PCM, red w/black stripe or Pin number 44, gray w/light blue stripe
he means they arent that accurate on the stock narrow band O2 sensors, i think ours even turn off at WOT 
if you buy an innovate motorsports LM1 wideband kit youll know your A/F is accurate. it also has an analog output you can hookup to your autometer gauge

ok there all installed!!!! piece of cap, i just need to connect the sender wire to were they belong but i have to wait so i can run the wires with the injector connectors. this was like a 3 hr install, icluding hiding the wires putting, the pillar on, going to checkers once, and all that good stuff!!!!
