the directions say: "run the white wire from the zex unit to the output voltage lead from the TPS."
which wire is it on the TPS? i see 3 wires: green w/white stripe, red w/blue stripe, and pale yellow w/(not sure though)white stripe.
thanks

 

green with white strip

 

its whatever wire reads 4v at wot, i even installed one of those kits on a 4cyl ranger, it was still slow haha.

 

I put one on a 2001 auto accord 2.3 and it was still slow as hell !!

But my civic went from pretty slow to kinda fast ( 15.1 ).
