the purple wire you are seeking is on the actual A/F gauge itself,..the white wire coming from the O2 is on the O2 which is under the car on the down pipe,...run the purple wire through an existing hole in the firewall that has a grommet (remember kids, grommets are good) and then splice it into the white wire on the o2,..power and ground the other 2 wires coming from the guage and you got pretty lights,..my A/F guage takes awhile before the lights start jumping around after the car is started
