for sure man
If I can remember correctly (I basically just spent like 20-30 minutes fussing around with electrical tape and the contacts, lol) there are three contacts, a ground, a continuous, and a flash. Obviously you are looking for the continuous signal to black out. I "THINK" it is the contact that the purple wire leads to, but you can quickly find out by trial and error, there are only three options. Also, I remember trying to put the electrical tape over the contact and then pushing the light in, or vice versa, and it did not work (i kept trying for a few minutes... :rofl
but when i switched the method it went is much smoother and it was done, once again, going to be a trial and error sort of gig.
That is just the way I did it, BUT (actually now to think of it I may have gone this route... I'm pretty sure I was DIY'ing while under the influence
) you can also tackle it from other places if I remember correctly... like at the wires or where, WAIT, I think I did this... where the harness plugs into the socket... god I'm so confused on what I actually did now... just go with what is on top. haha
