i have a nx wet kit with the msd rpm activated window switch, well my kit is dont, but the only thing i have to do is to splice that wire in with the tach wire.



Now my question is.........................WHERE THE F*** is that wire??? lol i have no clue where it is or anything. please help, is it a wire that plugs into the computer or is it actually over by the tach itself.

any help will be greatly appreciated. Thanks guys

on the coil you have th epink wires and the white wires. i thnk you can tap into one of the white ones for a tach signal

 

i have absolutely no clue where you are talking about.......................i mean is by the tach itself or the computer???? Im sorry, but i have no knowledge of the wiring harness.................if you could please elaborate that would be great, Thankyou

He is talking about your coil itself...Mounted on the top front drivers side of the engine. It has 1 plug wire (coil wire) going from it to your opti. That is the coil. It also has a dual plug in the top of it that has colored wires. You need to tap into the - side of the coil which he believes is the white wire(s). I guess I should have asked...do you have a MSD ignition box? If so there is a tach output that you can plug right into.

 

no i dont have the ignition box i just have the window switch.............so thats where i have to splice the wire in at???

Um doesnt sound right, but im sure you guys are right,

If anyone else has any input on the subject please give your opinion.........thanks guys,

The PCM harness has the tach signal wire. You will have to look for sure, but it is on the red harness I believe. This wire can be tapped into and will give a more finished look than running the wire all the way up to the coil, which if I remember right is the alternate method if there is not an available tach signal from the PCM. Check http://shbox.com for the location to make sure. You will have to pull the PCM out 10mm screws and unplug the harness then find the wire.

 

i cant find anywhere on his site as to where the rpm wire is located........

 

Give that a try. And its for a 95 and you have a 97. sorry, it might help tho

circuit 121 isn't necessarily the same signal frequency as the output of the coil module. if it is then it can be used as an RPM signal also. if using that one works, let us know.

 

if you using that one works????.............lol


how do i test if it works or not??? i will be using this for N20 so im not gonna spray to find out if it woked or not...............is there another way i can find out????...............


what if i hooked up an LED to the switch..............would that tell me if it worked or not??? I think it would.......all it will do is supply power to something during certain rpms...............so it would work



Sorry i know i answered my own question, but thats how i think...........ill find out then let yall know


THanks, Scott
