04 chevy remote start

We are installing remote start and alarm keyless on an 04 chevy truck. we have got the bypass module i believe the number is a 457g it is a directed product. Anyways we have the alarm and keyless working. But it tells us to locate the passkey box to find the pink wire. Well i can not find the pass key box. there is a pink wire in the ignition harness but i do not want to cut anything before i am certain. Also what is this i hear that you have to have a third ignition to keep the transmission from messing up??? any help on either problem would be apprecitated.

Did you miss the note in the instructions about the 3-pin harness only being used on certain Passkey 3 vehicles? Your truck has Passlock 2. The 3 pin harness is not used. The only wire from the 457G that gets connected is the data wire. Gets connected to the purple wire in the OBDII plug.

You shouldn't need the 3 PIN Harness.

This is how I wire Chev P.U.s
