What are you installing by ignition switching? It all depends on how many amps it is going to pull. One relay might not do it.

I can't remember how big the ignition wire and 12volt wire is off the top of my head. Here is the info for those 2    Battery          RED / WHITE          (+)          IGNITION SWITCH HARNESS           Ignition 1          PINK          (+)          IGNITION SWITCH HARNESS       If the pink ignition wires looks like a 12ga go ahead and just tap in there. If it is smaller like 18ga, but the 12v looks like 12ga use a relay with this info to power up your sources just to be safe. 85 ground 86 ignition wire (Pink) 87 12volt constant (RED / white) 30 output wire to your accessories.

Thanks alot! I will start searching this weekend and see what I come up with.

I looked it up while at work and the best option is to hook it up to the ignition wire pink on the cylinder, and fuse your connection. If you want to make it a little safer there is actually a 50A handling 12v+ power wire in the BCM which is in the center console. You could hook a relay up there for sure. Just find a ignition wire to turn on the relay or run it from the ignition switch down to the bcm to switch your relay.
