1998 Teton Kingman wiring schematic.

Thank you all for responding

Your best bet is to get a "RVing For Dummies" which will provide the basics for most RV wiring.

1998 is pre-internet for most people and businesses. Further there are few RVs of that age stil around. Therefore, usually no online source.

Almost any RV manual is just a collection of the manuals that the appliance manufacturers put out and any other information is just about useless.

We have a longtime member, Chris Bryant, now retired from his RV service business, who has generously provided a link to many manuals, both RV's themselves and appliances used in RV's, on his company website. You can check out the various categories on his site
here.

You would probably be best served by looking up the model numbers of the various items in your trailer and then searching for the manual for each item.
Good luck. :)

As far as appliances, stove, refrigerator, furnace, etc; you can obtain those manuals by manufacturer and model number, online.

As far as a wiring diagram: You're on your own.
No manufacturer has one. All owners manuals are worthless.

I don’t know of any manufacture that has a decent manual.
