    What the converter does is apply intelligence to the brake and turn signal light feeds so it only comes out on one wire. Before the converter you have a signal for turn and brake. After it they are combined and it can handle displaying the flashing turn signal when both are receiving a signal. It used to be so you could combine the dual rounds to be able to do both bc they came as one was brake on bright and one was turn on bright. Since its a dual filament bulb. Then its just the running lights on the low bulb filament.

    A third brake light is challenging with this if its a single signal light. You could take either of the left or right brake/turn combined output form the converter. Brakes would work fine bit it would only blink with whatever side you took from the converter. What you want to do is take a signal from the brake (purple wire) BEFORE the converter. Then it would be a single uncombined brake light.

    Unless your 3rd brake light has a left and right side. I installed the 3rd brake light in my roll bars so I essentially have 2 and could take it from the converter. Here you can see my car in both scenarios: Brakes on and then eft turn on (no running lights).
    Thanks Michael - that helps a bit... remember these rectangular lights are LED, not separate incandescents like the dual rounds...

    so we should just tie into the purple... not cut it (like we did) ugh

    what's throwing me off is in Fman's post he's direct to the tails from the converter, not the harness
    and Brad's diagram below doesn't show a purple line at the lights either...

    so given the LED tails and purple lines are needed... it would wire as follows (with converter)


    GROUND black (harness) to white (on both lights)
    TAIL tan (harness) to black (on both lights)
    BRAKE purple (harness) to red (on both lights)
    RT TURN white
    (harness) to
    red (on right light)
    LF TURN yellow (harness) to red (on left light)

    3rd brake light
    Option #1 single light
    tie into purple (pre converter box) so it only turns on (no blink)

    Option #2 two lights (left/right)
    tie into purple (post converter box) so they can blink with turn signals
