Hi Ray and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.
Initially and if "...wired it up yellow and red together...", are these 2 wires then connected to an always available +12V source? ...or only when the key is set to ACC or IGN ?
Yes; yellow wire to an always available +12V source such as the battery's + terminal while the red wire to a source that would only have +12V when the ignition switch is turned to ACC or ON.
