84 is around the cut-off time when GM changed from the old system to the newer one. The old system has a separate relay and a separate controller - whereas the newer system the relay and controller are one unit. The old system has the relay on the fender-well. The new style controller is mounted on a coolant-block-off plate on the rear of the driver's side cylinder head. So, wiring a manual button can differ a bit. Basically though, you just want a momentary push-button, a relay (Ford type starter relay is fine), and a good power source that can handle 50 amps. keep in mind that if you have any glow-plugs that were actually made by Delco, or Champions, they will burn out and often blow up after 9 seconds of steady use. The newest Delcos - are much better since they are no longer made by Delco. They are reboxed German Berus like Ford uses in the IH engines, and have built-in current limiters. If you are having problems - check your glow-plug inhibitor sensor. It's easy to change and only cost around $13. Or better yet - bypass it.
