I did a search in here and few topics asked about how to make a shift light, but there was no answer. If anyone out there knows how please let us know. I just want to know which wire on the ECU should I tap into. Thanks for all responses.

 

the pin for the rpm's just like for a vtec controler.....just tap the line

 

what if you dont have Vtec??? is there any other way?

 

Umm, theres a RPM signal wire going to the ECU regardless of VTEC.

 

is there instructions on the web or anything for this??

 

why the ECU? I use the factory service connector to hook up a tach/shift light

 

go pick up an MSD #8950, which is an rpm activated switch, hook it up to the tach wire and choose your rpm with the pills that are sold seperately...
then find yourself and led or whatever kinda light u want and hook it up to the output side of the box..
I tried finding a cheaper way for myself but theres hella work involved to make the curcuit so just buy the box... it will be cheaper in the long run..
