I need help using my MSD window switch. I want the MSD window switch to stay on all the time, but only to turn off when it hits 5,800 RPM. I got the "pills" to turn it on and off. It is a WOT ZEX system. The MSD opens/closes a ground for the ZEX. How would i make the msd to stay on until 5800 rpm. And also why does the cars tach shut off when i turn the MSD window switch on?

 

cause you did something wrong??

 

i dont think i did anything wrong. all the wires are correct, for the msd window switch, i took power(spliced) into the distributer wire (blue one) for turning on/off at certain rpms. When i turn the window switch on, the car starts to idle rough, very rough almost shutting off, (posibly computer not getting signal?). The tach on the car also turn off, but goes back on when i turn the msd switch off, and car idles more normal. And for the MSD window switch, does anyone know how to keep it on for all rpms, until i want it to shut it off at 5800 RPM?
