If he just installed the 14cux system to the carbed engine it would already have the speedo hooked up to it.

Now that i think about it... when i was having problems when i first got the d1 it wouldnt rev passed 2500 rpm. As a quick fix i unplugged the speed sensor and it ran perfectly fine. After slotting the TPS the rev limiter stopped kicking in. Point is it ran fine withought the ECU feed
