Having trouble getting my nexiq to communicate through CAT's OBD2 connector with their 9-pin adapter. Engine is in a tow truck chassis from GM - 6500 topkick maybe? Runs fine when cold - several sensors replaced already (shotgun diagnostics).

99% of my experience is with light duty trucks and of course the 5.9L Cummins medium dutys. I gather that this thing runs HUEI injection like the Ford Powerstrokes? Don't know much else about it. Awaiting a special connector from Nexiq for this particular vehicle (gee thanks Cat/GM).

Any info at all would help.
