About a year ago I had an issue with the inside of my steering column and i should have replaced the column but i didn't. I hooked up 2 toggle switches for the wipers, and I had the use my thumb on a steel rod inside the column to turn the Hi/Low lights on and off. But last night they got stuck in the Hi and now I can't get them into low, so again I'm going to hook up a toggle switch for the hi/low for now till I can get a new column but I don't know what colour wires to look for, can someone please help. Thanks.
