having trouble with sr swap "please help"

[z32twosr20]

hey guys,

so Im swaping a sr20det BLACKTOP S13 in to a 318i bmw, I have spent a few days looking in the older posts and cant really find what im looking for.

the motor is all in, and im still trying to finish wiring it to the car. heres my problem, I have found plenty of info on wiring for a 240.but im kinda doing this from scatch so it doesnt help, so any input from you guys would be much appreciated.

so heres what I need help with...I need to know how to wire these in relevance to themselves not to a 240sx

on the body harness:the orange Ignition Start wire? IS IT JUST 12V SWITCHED?I know all the black wires are grounds

and on engine harness: Black-Pink stripe, Fuel pump relay-----?Green-Orange stripe, Transmission neutral switch---- ? Red-Black stripe, ECU relay------? Green-Yellow stripe, * AC relay---- NOT NEEDEDBlack-White stripe, ECU power----- ?Blue-Green stripe, AC relay--- NOT NEEDED Black-Yellow stripe, Idle air control solenoid power ----- ?Brown, O2 sensor power----- SO I KNOW THAT THIS IS 12V SWITCHEDRed ECU, backup power---?Black / Red stripe, Main ignition power-- 12V SWITCHED blue-red---?

SO DOES THE RED WIRE GET A FULL 12V. OR IS IT LOWER?

HAS ANYONE PUT A SR20DET IN TO A SANDRAIL, I KINDA NEED TO WIRE IT THE SAME WAY AS IF IT WAS IN A SANDRAIL.

SORRY IF I LEFT ANY DETAILS OUT THAT YOU NEED, IF I DID ASK AND I FILL YOU IN TO THE BEST OF MY NOLAGE.

THANKS GUYSPC
