ECU wiring harness layout question...

[sathu]

I got to the TSRM and found the SPD that I am gona splice into for the Greddy TT but I am kinda confuse here. Is the picture looking at the harness from the front of the ECU? I thought it was the back so I think I plice the wrong wire and I am gona have to redo it.

The view in the TSRM is towards the ECU. Simply look at the different plug pin counts (for left-right orientation) and the plastic clips (for up-down orientation) in the diagram.

I followed the layout base on the 22 pins with 11 on top and splice in my spd wire and it doesn't work. I spliced it on the 9th wire from the right of the one with one open pin slot. The color was pink with gray dot on it.

Ok I took it out for a really long drive of about 90 miles and my turbo timer work great with my factory alarm system w/o setting it off when shut down. However I went back to redo the spd wire, basically remove the crim and splice the wire directly in, and when it fire up the car idle at 1500 and then drop to 1100 and back and forth it go from 1100 to 1500 rpm. Anyone know what could be wrong with it? I checked the CPS wire and the TPS wire to make sure it's not loose and it still does it w/o giving out any code. I turn off the TT and remove the wire from the harness and it still does it. Mine is a 91 turbo and for some reason my TIL (turbo indicator) pin on the harness is empy. I have 3 empty spot next to the +B1 instead of 2 like the TSRM showed.
