Sorry if this is in wrong section and for the wall of text, any help would be appreciated!
I have an 02 supercharged xterra. Was someone woods toy, doors were off, no roof. Wiring was cut at doors. Still started and ran fine. 60k miles. I pulled the cab and put a 1964 Datsun 320 cab on it. After reconnecting the wiring harness just to mock it up and do a test start I noticed I had no blinking security light. I can hear relays click. Fuel pump is running. Will not crank. Started checking my anti theft system and it was all installed correctly. I read I may need to reset the anti theft by turning the key in the driver door a couple times. Obviously not possible with this set up. Secondly I never had to do this previously when it had the Xterra cab on the frame. I decided to check codes, sure enough I have no communication from the DLC. It will power up all my scan tools. However, no communication. Replugged the ECU. Then tried two other ECU's I had laying around. Both were identical ECU's out of other supercharged Xterra's. I have been messing with Xterra's/Frontier's for years and have never had an issue with DLC communication so I'm at a loss. Ignoring DLC communication and no security light I would have assumed either the neutral/park safety switch or the park position switch. I tried another shifter to rule out the park position switch. I'm at a loss. I have the whole harness plugged in everywhere besides the doors since I do not have the doors and they were never needed to start previously. I have all grounds connected and tested each ground with power probe. Starter gets 12v when key is in position so fusible link is good. Cluster comes on and looks to be responding, shows CEL and ABS light. ABS is unplugged so makes sense. I pulled and tested all fuses with the power probe. I even disconnected anti theft system and relay and no change. I can't decide if this is a traditional no crank issue or if the missing security light and no DLC communication is the culprit. What am I overlooking here? Thanks!
