'04 buick rendevous 555gw

I am using a 555gw to bypass passkeyIII on this buick. I have tested with the key in the ignition starts fine. I have column cover removed and I am ready to tie in this bypass. I've found pink wire off passkey cylinder 2 purples and the green keysense wire. It says to cut the pink and wire it inline with pink and pink black.  Purple goes to which 1 of the 2 purple wires I found, how I am supposed to know which one. If its a data wire its not testable? keysense is done.  Please bare with me I generally don't use these I bought out a competitors inventory. Any advice would be awesome.....

I'll answer my own question. Its the purple in the rear of the plug last purple.

I may have spoke to soon. I noticed while testing the security light in the gauge cluster is illuminated. Anybody have any ideas? It starts and runs fine. Anybody???

Did you power up the brown second accessory? If not, it will throw the security light. Also just FYI it shouldn't matter which purple wire you tie into. If you follow them down to a plug, you will see one dead ends. Mike
