    Hey all!

    I just finished my Bi-LED projector retrofit on my tacoma. I ordered a relay adapter kit so it would connect to the H4 plug and power the projector in the high beam mode. These tacomas have a ground switched circuit for the headlights so after switching the + and - of the adapter, the lights function great.

    I would like to get my high beam indicator light to turn back on as well and trigger auxiliary lights I have tied into the circuit with a 3-way switch (forced on, off, on with high beams) that functioned great with the incandescent bulbs.

    I ordered an H4 resistor and put it inline between the stock wiring and the H4/LED adapter. All lighting dead. I depinned the resistor's female H4 plug and swapped ground and low and was able to get the lights to turn on in low beam, high beam is under-powered, and the indicator and auxiliary lights still wont turn on.

    Is there a way to modify or switch around the wiring to get this to work?
