This DIY will cost you about $7.50 (if you have a few conectors and wire laying around.) If not 15.00 MAX
So start by taking out the coin tray.



Next Locate the Blue with Pink Wire. (this gets 12v when you LOCK the vehicle.)
It is the Top left Wire that you are after BLUE/PINK
I ran a wire through the firewall using a stiff wire to first poke a hole and then pull the wire through. (I used a red wire)

Here is the wire pulled through.
Attach all the wires to the Peizo Buzzer
(Red to the Signal Wire from the BLUE/PINK wire.) I used a scotch clip to attach the signal wire.
Next the Black wire to a ground. (I used a self drilling screw and attached mine directly to the fender.)
I used double sided sticky tape to attach the Buzzer.
There it is You are DONE... Under 20 Mins and you have a BEEP!
If you read this hole DIY you could have already had this done!!
(yes it will beep with the truck running as well. Only downside to this mod.) But I like it better than attaching into a turnsignal and having to flip a switch when you want to use your hazzards without a beep and the car off (Moerse version). And a third of the price!
You can make a donation to your favorite charity with all the $$ you saved! (or paypal ME!! )
Part Number and receipt.
