There does have to be one, but I didn't bother to check which one when I installed my aftermarket HU. I already had the switched power block from under the hood from my gauge and nitrous install. I didn't bother to check, sorry.

Go to the ignition harness and check the Pink wire for switched 12V, it should be good to go.
