    Tach not working?

    I got the engine to fire up but I'm not getting any readout from the tach....and the whole dash for that matter...seeing as I only ran it for about 20 seconds. Any suggestions?

    If nothing on the dash works- I say tripple check your wiring harness. If you messed with your fuel pump, make sure you remembered to attach the fuel level sender(s).

      The tack is simple, its just a (black iirc) wire from the wiring harness to the plug over by your DME.

      The dead dash is somethign to do with the body wiring. Fuse, wiring, grounds.

        I'll check if the fuel gauge is working and I'll take some pics of what I think it might be tommorow. Thanls for the info though.

          Ok heres the update:

          The fuel gauge goes right up to where my gas level is when I turn the key to the run position so the dash seems to be working alrite. Here are some pics of some wires around my ECU under the passenger dash.

          These 3 wires came off of a plug that came from somewhere towards the drivers side...I'm assuming to the dash:



          And this is a black and white wire coming off of the ecu harness, that someone attached a long blue wire to the end of it.



          And this is some other random thing that is just hanging out.
