Basic S13 Wiring for SR Harness ONLY

[SiI40sx]

Ok I dont know if anyone else is in the same boat with me but this is going to be my first time doing a SR harness for a 240sx S13 swapping a SR20DET Redtop. Im planning on using heavythrottle for reference on doing the harness but I keep hearing from other sources that Heavythrottle has incomplete information. This is what I know

--------------------------------------------------------------------------
KA Harness has 2 plugs at the end
SR Harness has 3 plugs at the end

Re-wire the SR Harness so it matches the KA's two plugs (make the male "sr" match the female "stock plugs")

Extend the P/S Wires and the MAF Wires

In the SR FAQ theres also this as reference:

BTW whats F10 F8 E10 E9??

From my understanding thats all I know. Is this how you guys did your harness? Everywhere on zilvia and zilvia affliates have incomplete information about doing the harness. Mods can you please sticky this thread and have it for reference for all zilvians doing basic DIY S13 SR Swaps. Hope this thread has a future. Thanks
