NEED HELP FROM A 240SX PRO.(for wiring)

[drft204]

hey after i finished the sohc to dohc swap, the gauge cluster doesn't work. the temp gauge goes everywhere, the fuel gauge goes crazy too and my tach doesn't work. i dont' know if the speedometer works becuz i haven't tried driving the car yet. oh yeah and the gauge cluster's lights don't work either. everytime i turn the lights on with the key in the on position it flashes about 5 times then it turns off. i noticed that theres another module or w/e that is behind the ecu and has 2 connectors. i'm guessing it could be the pcm? on my sohc harness there are two connectors that connect to it and its location is between the dash connector and the ecu connector. anyone know what these 2 plugs are and if they have anything to do with my gauges not working because my dohc harness don't have them.

you have to have those wired up under the dash in order for it to run properly and for the cluster to work. i believe there is a writeup on the tech pages on how to do it. basically you match up the colors and you'll have a few left over. Your tach just won't work afterwards unless you swap out for a dohc cluster.

okay i'm pretty sure that the dohc harness has those two plugs and it should jus plug right in.

this is the plug i believe the write up is talking bout. cutting the wires and matching them up.its all matched up couple wires hanging loose though.

and these are the plugs i was talking boutthat was connected to the sohc harness.

sohc is trash you need a dohc wiring harness nearly goes for 100 bucks or so.
