Default Msd window switch

Trying to figure out where I get the rpm signal from. Is it the blue connector, white wire pin 35 on the pcm? If so....where is that? Help me some here.

That is what I have done for the last several nitrous installs. Have not had a problem out of it.

Same for 98 cars? Do I just strip some of the wire back and solder the wire from the msd on?

To test you can feel them and rev the car. You should feel them open and close. If you want proof you can make a mess and put your nozzle in a bottle or something so that it isn't blowing into your motor. Then you would see the fuel and nitrous coming out.

Feeling them should be plenty good but it is up to you.

P.S. Other ways would be to test with a volt meter to see if you get juice
(power not nitrous)at the noids, take it for a spin around the block.

My wire was green with a white tracer like you said.

Did you split the wire for tach input? Maybe you didn't get a good connection of the original wire. Ideally you want to use a pair of automatic strippers that will just cut the insulation and open it up a bit.

Ok that picture must be wrong for 98 cars. I wired into the white wire, pin 35 on the blue connector. Works perfectly and no codes.
