jsut a quick thing i did some reading and just want confirmation

just wiring to the stock ecm harness is all i would have to do to tell it wheich gear its in and all that fun stuff


i shoudlnt have to change the ecm or prom

but if i installed a shift light in teh gauge cluster how will the ecm tell it to light up?

 

in order to use the factory hift lite you need a 5spd prom or it will light at the wrong times. as far as wiring goes you need to adapt the neutral safety to give you backup lites.

There's nothing inside a t5 to tell your ecm what gear it's in.

 

right but im jsut concerned if i wanted a shift light to work in my gauge cluster

i can shift from listening to the rpms jsut curious if i can keep the ecm and prom as is or if i need to delete the torque conveter switch on the prom or beok by jsut leavign it disconnected
