Here is how I did my leds and links to everything!
Yes I have the TST, and stock signals, they supply relays you can wire inline if you like or the one you put up front but that disables the flasher blinker on the interment panel. I just hooked my tst up no relays or anything and it works fine with the stock blinkers up front!En187 is that the tst integrated tail light? And if it is I see you are using the oem turn signals up front? Did you have to use the flasher relay for that to use the signal at regular speed? I want the tail light but dont want to have to put the flasher relay in. By the way your Z is dope!
