r33 rb25det conversion into a31 cefiro wiring problems.......

[damla]

heya after some help, ive got a 1991 a31 cefiro originally was rb20de, i had a rb20det from an r32 that i was running in it that i used the factory cef loom an it plugged up sweet, ive just compared my loom to the r33 loom i got with the engine and it willl all plug up to my factory loom except the injectors which i can marry up no problem, wat i nned to know is: the r33 plenum on the rear has i think wat is called the idle control valve? anyway the rb25det has an extra bit with a purple socket that i dont have a plug for on my loom, and also at the front of the head on the r33 rb25det there is a sensor? or something thats sticks out that i dont have a plug for on my standard loom, from wat i understand its for the vct or something? wat i need to know is where would i need to wire these to be able to use the exisitng loom that is in the car? i have the r33rb25det engine loom but it is drastically differnet from my factory loom in terms of where the ignition module and some of the intake sensors connect into the loom. i have pics of the items i have questioned about but i cant figure out how to post em so if anyone could help me with that too. lol.any help appreciated.damla
