1983 accord clock

Yellow/red is accessory..so if you want the clock on all the time that will go to 12v+ constant

WHITE/ blue goes to constant 12v as well.thats the memory so it holds the time when the key is off.

RED / black is illumination...when you apply 12v to this wire the clock display should dim..this is so it's easier to see in the day..and not so bright at night..you decide if you want it or put it on a switch so you can choose.

that leads me to believe the RED / black dots is negative, however I am not 100%, I am going by hondas wiring from 83..damn thats old..and the only info I have for ground is chassis..I guess if it don't work try switching the RED / black and RED / black dots to negative
