hello community i have purchased a speed cut from greddy type 'a" for my sc 300 with a 1jzgte-vvti , i need help really , i need to know what wires to tap into my ecu . I know already the wires for the speed cut , there are 5 wires coming from the speed cut itself which is red, black , yellow,brown ,blue . red is for positive and black is for negative and 2 of the wires go into your "speed sensor" but i don't know which "color" wires to tap into my ecu , any help will be appreciated , please don't repond with links as i already gone through all of them and all it tells me is what wire is what on the speed cut itself. I need to know what color wires to tap into for my ecu , thank you everyone .

 

Not sure of what colors but i think its 3 pins on the ECU.

+B, SPD and E

Call Greddy in California and ask to speak to a support technician. They will figure it out for you. They're really helpful.
