o2 sencer

just run that purple wire to the 1 wire of your o2 sencer. pull back the wire on the o2 sencer because it is coated with a pertechtive wire that dos not do any thing and it should work perfectly. good luck

alternatively...

as you are looking into the ECU, middle connector, bottom row, second from the right. it a tan wire. confirm here if you like...
