From the harness/relay, I connected the white wire (ground) to the connector marked "c" on the fuel pressure safety switch. Then, the yellow wire form (MSD window switch wich is open switch to ground)I connected to the connector marked "NO". BTW: My kit is a Nx wet kit and wire colors may vary. Also I have an MSD window switch instead of the Harlan wich wire colors may vary as well.

 

My friend told me to get an MSD window switch for the NX kit I am buying. I've heard bad things about MSD, but he said it's because people are connecting it wrong. Something about the solenoid and relay. Can't remember exactly what he said, but what do yall use. The MSD window switch according to him cost about 60 to 70 bucks. This sounds good compared to NX's window switch that supposedly cost 279! What a huge differenc. Can yall give me feedback please.

 

Here is how I wired up my harlan window switch and it works perfect. I modfied the NOS diagram to include the window switch. It is small but readable.
