OBD port location 1990 Fleetwood Southwind P30 454

I have a check engine light that comes on after about 5-10 miles at highway speeds and stays on until the engine is shut off and restarted. This has been happening scince I bought the MH about 5 year...

You may have a OBD I on your coach. If so, It would under the dash to the left of the steering wheel, That's where mine is located. Hope this helps.
