I'm installing a relay for my stock ignition and aftermarket coils. I've read many posts including Posplayr's excellent write ups. I've made the harness modifications involving the stator wires (all three legs wired directly to the Compufire) and the righthand handlebar switch in the headlight bucket. I'll use the stock fusebox accessory circuit to power the relay which will be mounted next to the ignitor. What I'm not quite clear on is where is the best place to connect the relay switched power to the ignitor/coils in the factory harness? Thanks for the help!

Where to power stock ignitor/coils for relay mod?

My suggestion would be to use the wire that comes from the fuse. If you want to cut that wire and make things permanent, leave enough room on either side of the cut to splice in a wire. With the wire coming from the fuse, connect it to terminal #85 or #86 on the relay. Connect the other terminal (#86 or #85) to ground. The cut wire that leads into the harness will connect to terminal #87 on the relay. Terminal #30, of course, is connected to battery power, using a fuse. I suggest connecting it to the battery terminal of the starter solenoid. It is electrically the same as the battery, but you won't have to fight it if/when you work on the battery.

Because I modified the harness in the headlight bucket and wired my three stator legs direct to series regulator. Connected kill switch to one of the old stator wires that went up through the switch and now that wire is used to trigger the relay. Relay power comes from fuse box aux circuit.

At the end of your 'mod', you will need to have power from the battery to the relay pin #30. Power from relay #87 needs to go to your coils and ignitor. Either pin #85 or #86 on the relay will be triggered from something after the kill switch, the other pin will be connected to ground.
Since you have modified your wiring, it will be up to you to determine what wire feeds what.

Yes, understood. Thanks for the help. I understood pretty much all of this except for the best spot to tie into the Orange/White ignitor/coil circuit given that I bypassed the right handlebar switch connector up in the headlight bucket. Turns out I bypassed the ignitor connector by the battery and created a T with the power from the relay. Works great. I've got great voltage at the coils.
