marquee electrical question

I just replaced the starter and light on my 1 slot dedicated cab and forgot which wires connect to the power wires. On the light fixture there is a white wire on the left and a black wire on the right. Comming up from the back of the cab is a blue and red wire. Any one know which wire goes with which? thanks

I"m guessing that white goes with blue and red goes with black. can anyone look in their marquee and check for me?
