Hi fellow forumers :1zhelp: ,
Does anyone know what should be done to switch ignition in set up mode? It's 1988 Plymouth Horizon 2.2 - GM Monopoint injection. As far as I remember there's a socket somewhere that has to be grounded or two leads of it have to be jumpered. Then I can use stroboscope to set up initial timing.
Any info would be greatly appreciated.
