LT1 Swap...C230, C220 PIN questions

Hey I am just finishing rewiring a 97 Harness into my 87 Iroc. Now I am left with 3 wires to hook up and need to know what to do to them.

C220 (white connector)
PIN
G------Dk Green/White---Vehicle speed sensor- ( Is this just for the gauge?)
J------Dk Green/White----Fuel pump relay control-(not sure where this goes on a relay)

C230 (blue connector)
PIN
K-----Purple----Output Field Servie enable. (not sure what this does...i tracked it to the DATA plug BUT I am OBD1 now)

Small 3 wire pin (brown,grey,blue)

Brown-deleted
Grey--Deleted
Blue---Fuel enable signal (where would this be wired to?) I copied my old harness and I have a VAT1 box on it. is this for theft so it shuts off the fuel pump?

Thanks

Jay
