    hi,

    i've had this problem since i bought it and did a lot of things already. finally today, with my friends, i had the time to look for the electrical problem coz i occasionally use this. most of my searching said to look for the circuit from the pcm to the tccm which is a gray wire with black stripe on a 4pin black connector. however, i couldn't find the wire, it's either black or gray only without stripes and they all go down to the underside not the pcm. correct me if im wrong but is the tccm located at the back of the driver side air vent near the door? i hope somebody could post pictures where these are located so it could be a lot easier.

    thank you very much.
