ABS LIGHT AND BRAKE LIGHT STAY ILLUMINATED

I currently own 2 of these trucks, in total ive had 6 of them .. i know i must like abuse right..lol. on your cruise not working. try this the big flat panel on your dash under the steering wheel. remove it.now this is assuming you have a tilt unit. money bets you do. but anyways the main feed wire i think its called D3 goes out to the fuse box as well as many other wires and a very fine i think again green wire. the problem is that over time using the tilt under normal circumstances those wires start to break. the D3 goes right to the key switch. if that breaks while out on the road. you have 4200 pound paper weight. good place to start. as for your brake light and abs most likley its the abs card or trigger that is located on the center of the rear axle housing. alot of times just replacing the card. if it comes back in a week then its probobly the trigger. not that its broke. this thing goes thru the housing and reads the teeth on the ring gear. and any little wear or a slight chip and they dont read right.. i quit fixing this problem on mine.truth is this thing is the second most delicate thing on the truck... the junk transmissions are the first.. sorry had to say it

As far as the cruise control look under the battery, drivers side one if a diesel and there is a vacume line for the cruise. This vacume line always breaks right under the battery causing the cruise not to work.. Ive owned 2 2nd gen dodges with non working cruises and this was the problem on both.
