SGI 5 91 z28 wiring question
Hey folks just wondering if anyone can help me out. I just received my sgi5 and am trying to confirm my application needed and which wire to splice into. I put a 4.56 rear end in my 91 z28 tpi so now my speedos out 60% ish so I want to use this device to correct it I believe I need application 2 if I'm reading the destructions right and I need to splice into either the yellow or purple wire on b9 and b10 on the ECM. Can anyone confirm this and which wire to splice into for the sgi5 input? Thanks in advance. I'll be tackling it this weekend

B9 is ground, B10 is the high side for the waveform.
Cut then connect the yellow wire from the VSS to the “Sig. In” terminal on the SGI.
