I have a bus with a Cummins diesel engine, ISB 230, 5.9l, 98.5 year model with the vp44 injector.

I figured that it would have the same OBD plug to plug in a scangauge into, but going under the dash, I found a plug that looks totally differrent.

instead of D plug, it's a rectangular plug, with a clip on 2 narrower side.

it appears to have 10 total leads with 5 of them actually with a lead. (wires seems to have been cut, only one wire is dangling from it, but that's a whole another problem)

have you ever seen a plug like this? is there a converter? I have noticed that the most parts are interchangeable with a dodge ram truck of the same era, so this comes as a surprise.

I appreciate any enlightenment opcorn:

i know that some other the old busses with a detroit in it had a D deck diag in them. i had to borrow one from a buddy down at the mass transit shop here in town. maybe that has the same thing

d deck diag?

if you are talking about DDEC? I thought that was for "Detroit Diesel engine diagnostics".

mine has the DODGE 5.9 diesel ISB just like the dodges, all parts and electronics are interchangeable (supposedly).
