I was looking for switched power from the trunk.

The relay panel has two rows. There are 6 relays in each row.

The #12 relay, last to the right on the botom/second row, is not used.

I started testing by plugging two male end connecters, a positive and negative, to the relay checking the different combinations. Some combos had power always on... some had no power.

The combo that I stumbled upon were the two circled tabs. Now... #12 isn't a 53 relay, I just used the photo to illustrate where in the #12 socket you'll want to plug your wires.

You'll have to figure which wire will be which, I forget.

With the key in accessory all on... there's power to those two wires. When the key is removed from the ignition... what ever is plugged into the wires (light... radio... etc.) will remain on for about 10-15 seconds then the power goes out.

I'm not an electrician... so hopefully my explanation makes sense. I just couldn't see any sense in cutting into exposed wires... in those thick looms... when there was a much safer alternative.

If I was unclear in my description please ask and I'll try to be clearer.

Cheers!
