2007 Express Ignition Wireing

I have a post in Audio & Electronice but no one has offered an answer.

What I need is the location and how to identify a wire under or near driver kick panel or under the driver seat that is hot with ignition on.

I need to tap in to trigger a relay.

I understand the large ( 8-10 ga white) up near steering is ignition hot but this is too large to use a wire tap fitting.

 

I would prefer to tap into a wire from one of the 2 large connectors but haven't identified which wire is Acc or Ign hot.

I would start with check the top white plug for the pink and light pink and red wires the light pinks should be switched power but cant remember off top of head. But maybe this will help.

Thanks for suggestion on White and the Pink. I tried those because White & Pink are supposed to be Ignition but neither seemed to work.

 

I did find an Acc wire under the kick panel.

Green wire (10 or 12ga?) in the lower plug

 

 

 

I now have a functioning TPMS and a switched 12v outlet for my GPS.

I used a relay which I placed along with the TPMS receiver under the driver's seat.

 

Almpst looks OE.
