2WAY i need your help

[ik3vini]

Ok,

so i bought vatik tail lights for the celica. They turn the brake and turn signal and running light all into one bulb(dual filament)

how can i wire this properly into the factory harness.
there is no brake light wire coming from the lights, just a turn signal and running light.

the reverse lights and running lights plug into the factory harness directly. i need to make a harness of some sort so that if im signalling left and braking at the same time, my left brake light flashes as a signal.

if you could be of any assistance i would greatly appreciate it.

the only thing i can think of is using a wire tap?

[ik3vini]

i think it has to be some sort of relay, a wire tap using the brake wire would result in a solid light even while signalling i think.. im just not very good with relays and stuff, maybe he can help

The easy solution is an over the counter trailer light converter. Might need to add load resistors.
