ok... so i just got done with my sr20 swap... or so i thought (s14 blacktop into a 95 240) i have looked thru the forums for awhile now and im tired and frustrated

so my problem is... i think it has to do with the wiring. i am not getting spark or fuel... the fuel pump is not coming on when i turn the key for the 3 seconds or however long its supposed to before you start it. The wires for the fuel pump in the trunk have juice (checked with test light) so i was thinking it was the relay or something. (Black/pink wire) i have a couple different install write ups that give this little diagram for the SR and KA harnesses

Black / Pink stripe Fuel Pump Relay - Black / Pink stripeGreen / Orange stripe Transmission Neutral Sensor - Green / Orange stripeRed / Black stripe ECU Relay - Red / Black stripeGreen / Yellow stripe AC Relay - Green / Yellow stripeRed ECU Backup Power - RedBlack/Red & Blue/Red(connect together) Main Ignition Power - Black / Red stripeBlack / White stripe ECU Power - Black / White stripeBlue / Green stripe AC Relay - Blue / Green stripeBlack / Yellow stripe Idle Air Control Valve Power - Black / Yellow stripeBrown (to O2 sensor) O2 Sensor Power - Any 12v switched source

I however.... do not see these color wires anywhere on my sr harness or where they would need to go. I recieved the blacktop motor with the whole harness, fuse box and ecu. I have everything installed using the KA fuse box (not sure if i was supposed to use the KA fuse box or the SR one) if i used the SR harness i would of had to cut and splice all the wires coming out the front of it for all my lights and what not. The only splicing i had to do was there were 2 plugs that came out of the fuse box and i had to switch the connectors on the end of the plug to plug into teh sr harness. I did not see the color wires anywhere that are mentioned in that list. I dont know if there is a plug i am missing or if it is a different harness or what. I dont know where that plug is and those color wires are =(

Im guessing these wires in that diagram is my problem for my car not having spark and no fuel and what not, therefor not firing... cause i have no idea where they are or what to do now.... i am stumped and feel like giving up.

also... the only s14 sr20 ecu pinout i have found is in japanese or something and cannot read a damn thing on it.

Any and all help is much appreciated, i havent drove my car in over a year and i just wanna be done with it...

thanks
