you should have a

parking lights wire
tach wire
power
ground

tach is a white wire on the PCM
Parking lights you can grab right behind the switch, i THINK its brown...power you can get from the IGN harness, i dont remember if you want constant or ign power...constant is red and ign is pink...and ground it to any metal surface..

you want ignition power so tap into the pink one... no use in always powering a tach to read RPM's when the car is off.... unless you REALLY want to make sure the engine is off :)

reason i wasnt sure is most tachs now have a memory recall...Dont remember if thats stored electronicly or not.
