1978 Pace Arrow park light don't work

[vacuumbed]

On my 78 Pace Arrow (Dodge chassis)  the dash lights and the park lights don't work, but the headlights do. I repaced the headlight switch,  no change. I'm thinking it may be a bad ground.

I tried to find a wiring diagram for this in the members area, but it gives me an error. Does anyone know where I can find a wiring diagram for this?

Please do not take this wrong but,
In order to acess all areas of the site you have to become a full member.  You can easily kill many birds with one stone if you simply go to the club store and purchase a 78-82 Dodge MH Service Manual for the small sum of $14.95.  It covers chassis hydralic, suspension, wiring, etc.  Not only will you then become a full member with access to all areas of the site, you will also be able to easily answer many of the questions you have had.  Additionally, in the case of electrical wiring, you can only use the chassis mfg documentation up to a point.  The coach builder (Winnebago, Pace Arrow, etc.) modified the base wiring to adapt to their needs.  Sometimes it's just a matter of hand over hand research.
