Like it says, I did the mod But and I got battery voltage at the coils. But I have no spark. I guess im confused about which wire to use as the trigger wire.. I have a 1981 CSR 1000. If someone one could clarify which wire that would be great! thanks...

I have never seen a 1000 but for my 750 there was a yellow wire with a red stripe and then a signal wire. The signal wires on yours are Green for 1 and 4, Black for 2 and 3 (I Think??). Maybe I have that reversed. Anyway the battery power coming out of the relay goes into the Y/R wires to make it work right. I don't know for sure if this is right but I'm 99%.

ive got a a yellow red wire. Ill have to post pictures of which wire ive got. Probaly my luck theres two red/yellow wires and I have the wrong one.

I've done this on my CSR. It IS the red/yellow wire you want for the trigger. You may need to open up the wrapped wire bundle that runs above the valve cover. Here's the description from WG's writeup:

Find the yellow/red wire that had previously been used to power the coils. It comes out of the wiring harness above the valve cover. This wire terminates in a dual outlet female connector. From this connector, voltage connections are made to both ignition coils. Remove these connections and discard them. Solder / shrink wrap a wire coming from the #86 relay pigtail sufficiently long to reach this connector. Install the press-in male connector and plug the connector into the dual outlet connector coming off the wiring harness above the valve cover. This is the relay TRIGGER. Note that the trigger wire is controlled by the motorcycle kill switch which must be in the ON position for the relay to function.

This should tell you exactly what you need to know.
