How to do the headlight flasher EV mod

I tried to do the headlight flasher EV mod, got it all done, but it doesn't seem to be working. (I think I had too large of a connector on the purple wire coming out of the flasher harness.) I'll fix that, but I see conflicting instructions about how to handle the purple wire from the connector. It seems that efusco says to pull the wire out and replace it with the mod wire, but CoastalDave says to tap the wire. Which should I do?

Thanks.

 

Well, I finished the mod last night and it works just fine. I ended up pulling the pin with the purple wire from the flasher assembly and replacing it with the new wire rather than tapping into it. I figured I didn't need to be flashing the high-beams whenever I turned on the mod. (Plus I never flash the high-beams when the lights are off anyway.)

Mod works great--only plan to use it to impress people by being able to drive away in stealth mode.

Thanks to efusco's great instructions, it took less than an hour, even with having to take the steering column apart twice and waiting for the soldering iron to heat up twice. Total cost was less than $5. It was fun cruising around the block in stealth mode last night!
