I have a 2000 450 7.3 psd with 154,000 on it. I changed the
injectors. I got in a hurry and forgot to hook up the harness
on top of left valve cover. I believe it's for idm, before trying
to start it. Is it possible I could have damaged the idm or
pcm by not connecting it. The engine runs fine but it keeps
turning in the service eng light. I have a chip in it but I had
it in the stock setting during intial startup. Didn't have any
codes before I changed the injectors. Does anyone have
any ideas what I might have done? Thanks Skip
