1993 Nissan Altima Electrical problem

I recently bought a second 1993 Altima as a project car with the intention of replacing needed parts from the Altima that I already had (accident victim!). The new Altima had a wiring problem where a bundle of wires that are routed over the drivers side wheel well had fallen and was rubbed raw by the front wheel . (For some reason, somebody had removed the wheel well covers from both front wheels.) It appears that a bundle of wires coming from the firewall side of the engine came into a connector that split the wires going to the front of the car. My guess would be lights and other devices sharing the same supply. I painstakingly rewired the bundle using connectors from the old car, paying close attention to matching wire-to-wire. I now have a problem that the engine won't shut off when I pull the key!! (I have to pull the fuel pump breaker to shut the engine down.) Now - it looks to me like someone has done this before just by the way the breaker and surrounding area looks. It doesn't make sense to me that the rewiring that I did would cause this. Does any of this make sense???
