i had just purchased the apexi turbo timer, i figured out how to hook up all the wires except the three that go to the ignition switch, can anyone please let me know which wires go where. i am aware that there is wiring harness i can use to avoid guessing, but i like to use this as a last resort. thanx

 

The wiring harness is 7$ from mazdatrix. Its really worth just getting lol. When you order it be sure to order the trust harness, its 7$ and is identical to the hks harness (25$). Im using the trust harness on my hks turbo timer with no problems.

 

YOURE SO RIGHT I BOUGHT THE HARNESS AND IT TOOK ABOUT 5 MINUTES TO HOOK EVERYTHING UP, THANX
