wiring up a sr20det for a 240sx help

[halyoder]

i have some diagrams from heavy throttle's web site but the colors on the wires are not the same and i think there diagram is for wiring up a 89 to 90 240 not a 91. please help if you have any info on this or know where i can get some info. one other thing is on the end of my sr20 harness there are 3 plugs that plug in to the sr20 fuse box in the engine bay that are not on my 240sx fuse box. every thing i read doesn't say anything but to use my 240 fuse box. but were does the 3 plugs go to then?
