Where is my ODB1

[lonniep]

About a month or so ago we sold the pop up and bought a 1988 HR Aluma lite XL 30 ft. Just took the radiator out - needed a new core. While it was apart I replaced alternator, starter, water pump, all hoses, thermostat, fluids so if anyone needs any help I'll tell you what I did. Still going over everything. A lot of work so far but between my neighbor and I we've been able to figure things out. Everything except where the OBD1 is and whether I have a class A or a class C. Any ideas? Thanks.

It looks like a class A to me.  You have a dog house inside to get to the air filter etc?

I may be wrong, but if it is a 1988, I doubt that you have an OBD1.  You have a class A.  A class C will have a van front end with a coach body added on, usually with a bed over the van part.

It's a class A. It should be carbureted as 1990 was the first year HR used TBI I believe.

Thanks to everyone!  Guess that's why I couldn't find it.  And I definitely have a class A.
