ok i picked up a rb20 and iam in the process of wiring it up in to my 1990 sohc

so far i have the gray 6 wire rb plug figured out

RB----->KAblk/red ----> blk/red ,gray ka plug ,IGN power white/blk ---> red ,gray ka plug,Ecu memory white/purple--->black/red,gray ka plug ,IGN relay green/ornge--->green/orange, brown ka plug light blue --->blue/green, gray ka plug black/pink---->black/pink fuel pump from ecu pin 18 to brown plug

ok from know it gets complicated first i have two wires i dont know where they go a solid white and a black , its NOT on the 6wire rb plug but right before it it was just clipped off what do i do with these ?? here is pics :D





also my wires for the o2 sensor were ripped out so if anyone can tell me in what order they go that will be great .



and last but not least the dash interface plugs what do i do with these only real think i found was connect orange wire from the s13 to pin 43 on ecu, can someone shed some light on this i have searched but can only find bits and pieces but dont match up thank you in advance
