They are showing positive on one wire in a said location.  Then they show negative on a different wire in a totally different location.  This is normal,  the default output of the light flash circuitry of your alarm system may play a part in which polarity wire you select.  Find the wire and using a volt meter, verify the operation of the wire.

Both above diagrams are incorrect. The first one shows no negative lights, yet there are at the column just as Directechs shows. The Directechs diagram shows no positive lights, yet you can get them at the BECU, connector F, green, right above the fuse box. Either one will work.....Mike M2

a negative parklight wire is usually the trigger from the switch to the bcm to turn on the parklights whereas a positive wire is skipping the bcm and just powering the circuit directly

So either one will work, I think I'm going to use the positive one. Thank you for your input!
