I've heard you must have the right plug on the right injector Why is that does it? Also how could you tell on the wiring harness witch goes to the front or the back? or witch one goes to the Coolent sencer?

Why is that? Does it really matter?

 

Yes it does matter, your primaries stay on through the whole rpm range, hence the term primary, The secondaires come on ~3800 rpms. I hooked them up that way on a cust car on the first rotary I had ever seen. It ran like crap till I realized the harness looked goofy. I looked at the wiring diagram and pulled the boots on the harness and the wire colors told me I had them mixed up. Put them back to normal and it ran just great.

The plug to your water thermo sensor (back of water pump) should be green and most of the sensor that it connects to are green. gary

 

FRONT PRIMARY INJECTOR: light green wire and a brown wire
FRONT SECONDARY INJECTOR: light green and white wire and a brown and white wire.
REAR PRIMARY INJECTOR: light green and brown wire and a brown and red wire.
REAR SECONDARY INJECTOR: light green and red wire, and a brown and yellow wire.
If your car has the solenoid resistor below the air fuel meter/air filter assy, then your car NEEDS, no REQUIRES the low impedence injectors which should be around 2-3 ohms. The 12ohm ones ain't a goin to work.
THE WATER THERMO SENSOR: has a green and white wire and a brown and black wire.
