Starter stays engaged ONLY in park???

Well remember what we talked about. Get in on the key connector and check the yellow there see if it comes "hot" in start. If it does it might be in the bulkhead. Double check that you are in the BJ (E body) section and not the VL section (valiant/ Dart) so far as the bulkhead.

This is strange, the diagram I posted is page 8-209 which is supposed to be B-J (E body) but the diagrams at the start of the diagram section are different more like the one you showed
