the wiring diagrams will get you on the right track but computer needs to be flashed in order to remove the security features that shut the engine off after two seconds (transponder key)
Thats not entirely true. Yes there are vehicles that came with security from the factory. But even in the years that offered "security" PCMs there were also non-security versions. As I recall, security was first offered on 1999 model years. But anything prior to that is not a concern and anything 99-(i believe) '01 would just need to be looked at more closely. I think '02 is when they when to the 4 connector PCMs ( it was either '01 or '02).
