from what i remember:

RED - power
WHITE - ignition
GREEN - rpm signal(either from the ecu or distributor)
BLACK - ground

*and just make sure the brown and orange wires located away from the main wires are cut.

ok, you can hook up the white wire onto any 12v ignition source.

i don't remember which wire on the dizzy to hook up to, but on the ecu, you can splice the green wire onto the "A" plug(largest plug on the ecu), pin A21. *here's a pic from the swap "FAQs" thread, courtesy of BustedLx:

for the green wire, if you don't want to tap the wires on the ecu, you can also tap the YELLOW/GREEN wire coming out of the distributor cap. there is only one set of wires coming out of the cap and one of the wires should be YELLOW/GREEN. that's the rpm signal wire similar to pin A21.
