OBD II came out in 1996 which is why I have never owned anything newer then that. if something does happen EMP related. I figure that I will have to swap out the ECM and maybe a starter and alternator they both have diodes that are easily destroyed. I am currently driving a 1991 jimmy (Well maybe not after tomorrow) and the only spare electrical parts I have yet to aquire is the digital dash because they are spendy.
I wonder if having a ground wire attached to the earth would help if the vehicle was parked when something went down would help??
