Hi, fellow rotary enthusiasts.....I finally got my EFI system wired up, and I am now attempting to hook up the last few items so I can start this thing up, make noise and scare the neighbors.  I took a few photos, and labeled the items in question....I don't know what these sensors and connections are or should be.  Any help would be much appreciated. It is a 1989 turbo model engine, if that helps.  I will send this message in two parts, so download times won't be so bad. Items one and two are just underneath the oil cooler. Item #1 is a small threaded sensor with two wires coming out of it.  Item #2 is Larger, and has two connectors at the end.

Item 1, coolant temp sensor for the gauge in the car.
Item 2, oil pressure sensor

     In the second picture, Item #3 also has 2 wires. It is octagon in shape.

Item 3, coolant drain for the engine block.

     Item #4 is a plug on the lower tube of the water pump. I thought this might go to the turbo, if one were installed?

Item 4, yes this does go to a turbo when installed.

     Item #5  Is a plug on the upper section of the water pump, next to the water temp sensor.  (I actually figured out  and wired the water temp sensor, all by myself).

Item 5, this is a small hose barb, that feeds coolant to an apparatus that raises the idle speed until the engine warms up.

     Item #6 is another sender of some type, with two wires coming out of it.

Item 6, I don't recognise those fittings as being part of a Mazda car installation. Where did you get your engine?

Thanks in advance for your assistance in identifying these items.  I know many of you have been there and done that.  sincerely, Paul Conner
