Getting ready to install NX EFI single stage kit and will be using a Jimmy -Jams WOT switch, a MSD Dig 6 ignition (both are installed), and a Harlan window switch. I also have a Hurst line lock installed. I need advice on completing the electrical hookup for the Dig 6 (beyond the MSD wiring harness which I was already using) and the Harlan window switch. Any assistance will be appreciated. Thanks!

 

just take a hot while active line off the relay into the retard of the dig6

 

Thanks, Drew. Anyone else? Still not clear on the Harlan switch and where to mount it.
Thanks!

 

ik missed the window switch. you dont have a diagram that came with the window switch?

 

yes, I do. It entitled "an adendum to installation instructions-1/21/04". What I have is the small, black cylindrical component w/ 2 leads (white wire and grey wire) and a diode. According to Harlan's website, this is the "window switch". The diagram shows the white wire connected to a rpm/window switch (Dig 6?), the diode connected to a standard automotive relay across terminals 85 and 86 (?) with the striped side of the diode connected to the relay terminal feed with 12v. No mention is made of the grey wire. I have emailed Harlan, asking for clarification.
I have the same type of question w/ the Dig 6. The instructions illustrate connecting the 2-step limit wire (blue) to the wire going to the line lock solenoid. Not sure why, but I'm glad I have a line lock installed. For the retard stage, the pink wire is supposed to go to the nitrous solenoid activation wire (which makes sense).
I'm probably making this install more difficult than it is, but I want to do it right and not fry something (like my car!). I really appreciate the help!!

 

Anyone?? Also, where do most have the Harlan window swith mounted?
Thanks!!
