Adam - Seen Bomb Shit… says:  
black goes to ecu ground  
Adam - Seen Bomb Shit… says:  
red goes to ecu power  
Adam - Seen Bomb Shit… says:  
the one with the different connector on it is the output and the one with the same connector on iit as the power and grond was seed in  
Adam - Seen Bomb Shit… says:  
yellow/green on the ecu  
Adam - Seen Bomb Shit… says:  
try that and get back to me

do you guys think the output he means is the wire that goes to the speedo ? and the seed in is what comes from the speed sensor on the tranny ? is that the big fucking sensor thing ?

so theres 2 wires to the ecu, one goes form speed sensor to ecu, other one from ecu to speedo, i cut(unhook) them from the ecu and hook them up to the ones on controller?

Sasha is right…

you cut the speed wire and the green wire “from the speed cut control” goes to the Speed Signal Wire and then you attach the White Wire back to the other end of the Speed Signal Wire…

All your doing is take the speed signal into the “Controller” tricking it, then sending it to the ECU

I’m just not 100% sure “if Green or White goes 1st” but my buddy has one wired up to his Harness and its not in the car so I’ll check it out and let you know a.s.a.p

ok so I tap into the wire that goes from tranny SPEED SENSOR to ECU ? am I correct ? there are two wires that go to speed sensor, I am going to tap into it underneath the car by the tranny hence I cant find it in the harness by the ECU, which of the two wires should I tap into ? would this work ok ?
