Keeps running 1991 Itasca

After I start my 1991 Itasca, if I turn the lights on and then turn off the ignition, the engine keeps running. It continues to run when the running lights are on or when the light switch is pulled out all the way. To stop the engine, I must turn the head lights off. I assume this is not normal! Any ideas which wires could be crossed as I do not have a GM wiring diagram.

Maybe that is a new warning system to tell you that you left your lights on! If your vehicle does have a warning system saying your lights are on, I suppose that hot wire could be crossed with the ignition hot wire and keep it running? I can't think of where the headlight system and ignition would cross otherwise?.................ronspradley

More info

I have found the problem is caused by the brown wire in the light swith, it has a purple wire spliced in to it which is causing the problem It is a MM01 but is hard to trace. Why did Itasca use all purple wire!

I have just been doing some more testing. I have discouvered I need a wiring diagram but I have no idea who's wire this is or what it is called. If I connect the brown wire and do not splice in the 100656 MM 01, the engine stops when it should but the day light running lights do not work when the lights are turned off. I am wondering if there is a problem with the control box for the day light running lights, but I have no idea where it is.
