Ok, so I happend into what is supposidly a Tomei Limit over system (L.O.S) Model 2000, its ur typical black box with tomei sticker on it,  
no TM or R markings on it  
It looks identical to to the Greddy speed cut remover accept it has

1. Black (ground)
2. Red (power)
3. Yellow (?)
4. Greed (?)

Problem 1:  
It came off a R32 RB26DETT harness and im unable to find a referance to it anywhere online, as well there are no markings on it to indicate anything and im not sure if it is a universal one or ment for the RB26 motor only?

Problem 2:  
Baring problem 1, I can safely assume that the yellow and green wire are to split the speedo wire. but if it is hooked up incorrectly what is my worst case senario? could i fry the speed sensor or the ecu?

I will try and post a pic of it up as as soon as i can.

Thanks.

I’m sure it uses 1 wire as speed/rpm input the other wire is the modified output

just have to figure out which is which

I seriously doubt it would fry anything having sensor wires backward, and you have a 50/50 to get it right the first time
