Next are the things I need to solder on, but I want to be sure I get them right...let me know which go where please.

Red> 12V Ignition

Yellow> 12V Ignition

Black> Ground

Brown> RPM Signal

Blue> Speed Sensor

Green> Injection Pulse

Thanks in advance.

 

s13 motor 89-94 240 this really helped us out SR20DET Swap Engine Harness Wiring Diagram Guide SR SR20

 

-(tach)brown=yellow/red (pinout 3)
-(speed sensor)blue=yellow/green (pinout 32)
-(injection pulse)green=white/black (pinout 101)-this says its the injector drive output, correct me if I'm wrong.
-(ignition on)Red and Yellow(built in fuse btw)=which one is best to use? Pinout 36 (IGN (ignition ON, from ignition switch) - Black Red;
Pinout 34 (Start signal (from ignition switch) - Orange; or pinout 5 (Ignition Pulse Monitor (For Trip Comp ?)
?

Let me know if all this looks right please.
