as i said just be careful, if you have the lights on, then you go to hit the brakes and all 3 lights are on at once, you may send your fuse box into shock, it will blow a fuse, and then you have to go home and re wire it, so be sure to test it before you take it on the road
i believe there is 3 wires on one of the plugs.. that would be running, brake, ground?? anyways, just figure out the wire for the running lamp and splice into it... I did it on my mazda and it works great. just an idea...
