Need help wiring s-afc s14

[-the.k.w.c-]

i just got a s-afc and im having some trouble wiring it the apexi site showed me the wire to connect to but i cant get it to work it only lights up when i ground i to the frame..... the ground it said to use goes crazy when i use my multi meter it jumps around so fast i cant see what numbers


when i check the rpm on the unit it said 4200 rpm but im reving at 800-1400
on apexi's site it shows a throttle position wire but there is no wire on the unit that goes to it.


i have a 95 240sx with a zenki sr20det 5 speed any one that has wired one of these before please help me out because this should really be a easy install
