[TR] (no subject)

[Brad Kahler]

Hi Randy,

I used a 3-wire Denso a bunch of years ago and thought I wired it hot all
the time but it's obvious that I'm wrong on that.  I like the idea of
pulling ignition power off the coil and connecting the small brown with the
large brown wire.  Beats running a wire all the way over to the fuse box.

I've made changes to the wiring but I'm trying to not modify the new TRF
harness.  You never know when you might want to revert back to stock.

Thanks.

Brad
