PCV/Intake Manifold Heating Element Wiring EDIT: Solution Found

Hey all,

Currently in the process of overhauling my PCV system and I've hit a snag. On the underside of the intake manifold there is an angle connector (Item #7 in below picture) which contains a heating element. That heating element is powered through an electric connector (item #26)... while attempting to remove item #26 from item #7 I managed to pull the wires clean out of the back of the connector. Fortunately there are only 2 wires in question, but I have no idea which wire goes to pin #1 vs. pin #2.



I've already ordered a new connector to attempt to repair this, but I'm hoping someone can give me some guidance on how to actually wire it. Unfortunately both wires that go to that connector are jacketed in white so I have no way to distinguish between the two short of tracing them all the way back. Some forum research has lead me to understand that there have been some incidences of these heating elements shorting out and causing fires, so I'd really like to not screw this up.

EDIT: Got the info from a member on another forum - the wires *should* be different colors, but mine were both jacketed in white; one wire is hot (pin #1) and the other is ground (pin #2). Since my wires couldn't be distinguished by color I used a multimeter to ID which wire had continuity with chassis ground, then ran that wire to pin #2. By deduction the other wire has to be hot, so I sent it to pin #1.
