    Anybody got a wiring diagram or the pin read-outs for the Glow Plug relay on an 1989 Jimmy? My relay started acting flaky so I replaced it (new AC Delco) but that didn't solve the problem. I had already replaced the temp switch when I did the heads. So that leaves some wiring issue. I've got a (factory) diagram for a '90 but everything is different. Does Chilton have a decent wire schematic?

    If I had wanted to go manual, I would have already done that.
