TURBO TIMER help

Hey whats up. i just got a turbo timer and i already know where 3 of the 5 wires go. The red green and blue wires hook up to the ignition, i got that. But there are two extra wires, a grey and white one. Both these wires are attached to the same clip and i wanna know where they go. I have a RAZO turbo timer and i cant seem to get any info on the wiring. Im guessing one is for the E-brake but im confused cuz both wires are connected to the same clip???

i got the apexi, and 1 or 2 go to the oxygen sensor.
but that is only for the air/fuel feature. but I cant find anything on RAZO.
