I just tried to do a tank lift with a coil/ignition relocation. All seemed to go well until I tried to start it up. When I tried to start it, it just backfired and died. I'm not sure if it said it before I tried to start it up, but I looked at the speedo display and I get a "bus err" message and the red key is lit up.

I think I may have mixed up the cables going to he coil. Would putting the front where the back was and the back where the front was cause the problem??

Other ideas on where I messed up??

Thanks!!
