ttt!!!

 

PLEASE HELP!!!!!! <img border="0" alt="[hail]" title="" src="graemlins/gr_hail.gif" />

 

I believe you run the groud wire from your noid to your FPSS on one side, then come out the other side of the FPSS and go to the yellow wire on your MSD switch.

ttt????????

 

use the fuel switch, its 2 terminals, connect it somewhere between the window switch, and the 85 or 86 pin of your relay. (whatever one is ground)

i did that and doesn't work,had to bypass fuel switch it is brand new thought i hook it up wrong?????

 

The FPSS has been know to have issues. Try adjusting the threshold screw (under rubber cap) using a multimeter and with the motor running. Yours could be misadjusted from factory or god forbid a normally closed cicuit...I'v seen this before too.

Did you cut the 2 loops on the MSD window switch.

It is imperative that the wires that adjust for which motor you have (i.e. 4, 6, or 8) be cut. I think the wires are blue and red......anyhow.....they need to be cut. Your car should be wired as a 4 cylinder due to the coil packs. If they are not cut the window switch will not work. So in essence if you already nave the switched wired in and it is not working then that is prob what you need to do. (not to mention that either way, if it is not done it will read inaccurately!)

The loops are located on the side where the wires come out of the switch. They are small, but some normal wire cutters will work.

 

if you put fpss in yellow wire where do you ground solinonds?

 

You can ground the solenoids anywhere.

There is no "special" place to ground them.

Although you may want them to use a common (same) ground.

 

DO NOT DRIVE ANYTHING BIGGER THAN A RELAY WITH THE WINDOW SWITCH!! the ground that the window switch provides is only good for 1.5amp draw. here is a link to another forum i play on where i posted nitrous schematics:

you will note that i have the ground output of the Window sw driving the solenoid of a 12vdc auto relay. run your nitrous grounds through the relay contacts. you can incorporate your FPSS in series with that, or with your arming circuit, whatever. yes, you have to cut the 2 loops on the window sw as mentioned above. Good luck
