apex-i really dosnt tell you waht it's looking for on the ecu btu it takes the crank position sensor on the motor to modify the signal by 15 degrees either way across 5 rpm ranges (i'll never use the 7200 range, of that i am pretty sure.) it seems to need 4 connections to all toyota motors (3sgte and 4agze are listed and ecu diagrams are given) the four are marked on the MR2 and ALL TRAC diagrams as G1 G2 G- and NE
the install book is here

and you have the wiring diagrams for our motor so the only real question i have now is
where do green and yellow go?
