Msd window switch

TA1364 · 09-30-2009, 06:11 PM

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.

Here is an alternate ( Easier ) location to pull for the Tach

Male side of the plug top row of wires second from the left

Hope this helps

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

TA1364 · 09-30-2009, 07:19 PM

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

Also, how do I test the noids with the window switch wired in?

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.

So I am going to rev it to 3200 in the garage with hand on the noids? Lol that should be interesting.

custm2500 · 10-01-2009, 11:43 AM

I rev often with my noids in my hands.

TA1364 · 10-01-2009, 08:35 PM

So how do I hold the noids, rev the car and trigger the wot switch....

I have a 2001 GMC truck does anyone know if this wire is the same for me?

Chris@NitroDaves · 10-06-2009, 04:02 PM

It's the same but might be a different color wire. I've seen them Solid Green - Light Green w/ White Tracer - Turquoise

custm2500 · 10-06-2009, 05:27 PM

passanger side or drivers? or will either side work?

Chris@NitroDaves · 10-06-2009, 05:51 PM

passenger side

TA1364 · 10-11-2009, 10:25 PM

So how exactly do I connect these wires? Whatever i did the car runs like shit now.

custm2500 · 10-12-2009, 06:09 AM

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.

TA1364 · 10-12-2009, 08:36 AM

Yea I soldered it on, the connection is good.

TA1364 · 10-12-2009, 12:07 PM

I took the wire off, car runs fine/ It started throwing a code from that wire.

TA1364 · 10-12-2009, 03:52 PM

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.
