    I HAVE PLUGED IN ALL THE PLUGS ON MY AE82 4AGE ENGINE AND JDM MANIFOLD. THE ENGINE RUNS ONLY ON AEROSTART HAVENT LOOKED INTO Y THE INJECTORS ARNT WORKING BUT I FOUND 2 SPARE PLUGS THAT REACH TO BEHIND THE PLENUM CHAMBER, LOOKS LIKE THEY MAY GO 2 SUMMIN ON THE FIREWALL, ON THE WIRING LOOM AND WONDERED IF THERE IS SPOSE TO BE AN INJECTOR MODULE OR SUMMIN? GOT A YELLOW CIRCULAR PLUG WITH 3 PINS AND A BROWN RECTANGLE 2 PIN PLUG.?

    look on club4AG for the wiring pinouts and trace the wire colours.

    Yes, almost certainly the yellow is the MAP sensor. The brown will be the start injector time switch which is mounted in the sensor block on the very rear of the cylinder head. The one that has the two sensors. The other sensor on this block has a green plug

    pictorial answer for you my friend.

    yellow plug is for the map sensor as you now know, pic shows where the brown plug goes (like Parrot says)

    picture is of my JDM loom so should be the same as what you have.

    you can use an AE82 map sensor you will just have to change plugs, as only JDM MAP sensor use the circle plug. if need be i know someone who has a few JDM Map sensors if you want a JDM one drop me a pm and i'll suss it out for you.
