my green relays will start to click every few seconds and when they click it causes the ecu light the red light to go on and off eveyrtime the relays click and it wont stop intill i pull the batteyr out of the car..

has your car been working correctly and this just started happening?

as far as i know your ecu shouldnt be getting power until you turn that key to on. (excpt the backup power to ecu)

so with that info im going to say your feeding contstant power to the ecu and have a loose f3 plug. or whatever plug the s13 have.

black pink - > black pink. rewire it is only to correct things; you may encounter and fixes other potential issues. rb20 -> s13 is so simple. do it..
