where does the other wire goto there are only three power ground and another wire i dont have any intsuctions i bought it from a friend that hadnt hooked it up and one more thing does a evo gauge piller fit the RA

 

u talking about the a pillers? if so yea they fit if u look at them the evos insides are the same as the raLLis

 

power -> 12v
ground -> chassis ground
purple (i think) -> O2 sensor at the ECU

thanks guys if anyone is sure where to put the purple wire please let me know

 

does anyonw know where the ecu in my car is thanks and maybe by chance know which wire coming ou tis the o2 senser wire

 

it is behind the glove box area, sorta under the dash, take your glove box off and you will see it

 

I posted up a list of ECU wiring a few days ago. Search for it.
