just installed brand new apex'i neo. im haveing trouble with the throttle readings. when i try the initial setup it responds as "no good" my application is an 89 5 speed 7mgte. the wireing diagrams provided were inacurate and said to connect wires to where there was no pin. do i have the correct tps pin? what color should the wire be? could i possibly need a replacemet tps? thanks
