Installing Radio - Need help with wiring

[jk96]

Working on adding a radio to my DX45 and need some help with the wiring diagram. The speakers are straight forward but need help with the power, ground, etc. Can someone take a look at the attached diagrams and let me know what colors (Black, Blue, Red, & Yellow) from the radio diagram should be attached to numbers 4(HR200), 7(HR212), and 8(HR239) on the tractor diagram. I seem to have it working but have #7(HR212) unused and loose radio memory when the tractor is turned off. Any help would be greatly appreciated.

Got it. Didn't realize the wire coming off of the dome light was hot at all times until looking at the diagram further and checking it. All works fine now.
