ok this thing is pissing me off. light works. ground ok.. power ok.. but its not detecting anything... tapped the b15 on ecu..(also known as blue wire from disb) still nothing. all wires behind are cut for 4cl motor.. what am i doing wrong.. light goes on when i start the car...

 

is your dizzy or ignition messed up? my friends msd ign. messed up and the lite would turn on/off alot even when parked then he hooked up his stock ign. after the msd went out and the lite now works

 

not at all..dizzy seems fine. no check engine light.. car runs like a dream..

 

damn i thought it would help but if your sure but to tell you the truth my friend didnt know till it went to the dyno.

 

Did you connect it to the blue wire in the dash?
If that didnt work connect it to the negative coil wire.

 

ok.. never mind.. got it working... hhhehheheeh
the other end of the wire wasnt hooked to the tach.. hahahhahah stupid me.. hahahahahahah
