Since different year models use different wires (thank you Chrysler), all
you need to know is TPS, MAP, Primary Coil, ,Power, and ground connections.
There's quite a few Viper guys running the APEXi SAFC and SAFC-II ('94 -
2004 models) so OBD1/OBD2 doesn't matter one bit.
What year Ram do you want?

I've checked their website for a wiring diagram but they just have them for
the imports available. Can you email me the diagram for the one you've
installed on the OBD I Ram?
Thanks,
James
