Need Help wiring NX/Mallory I just bought an NX Wet kit used and it didnt have any instructions, and didnt have a wiring diagram. I tried Nitrous Express's site but its under construction.
Does any one have the installation instructions and wiring diagram for an NX wet kit with a Purge? Or does any one know where to find one online?
Also I found a Mallory window switch wiring diagram online but I am unclear which wire is the Tach wire on the PCM that it needs to be spliced into?
And is there a way to switch the wiring myself, if it was originally meant for an LT1 and mine is LS1 ?
Anything will Help....
Thanx, Ryan.

Let's start with the tach wire. Harlan puts this in his instructions for his Window Switches and Shiftlights.
Keep in mind an LS1 tach signal only reads as a 4 cylinder not 8.
As far as wiring goes it's not too bad. If they provided you with all the hardware you should have much of what you need. You can call the NX tech line directly and they can send you the instructions.
LS1 specific:
The RED connector on the PCM is the one closest to the flat top/cover. The BLUE connector is closest to
the bottom (not flat).
98 LS1: Tach line is Pin 35 on the BLUE connector. Tach line is a white wire
99-00 LS1: Tach line is Pin 10 on the RED connector. Tach line is a white wire
There are gray plastic covers on the connector. These will pop off. The wires are numbered under this
gray cover. Pop the cover off, find the appropriate wire and splice into it. Run the wire into the vehicle
and to your light.
