Re: Need directions for harlan two step I have it set up in the 1998 M6. The 98 M6's are the only ones that does not have a computer link, but I'll tell you how I solved that.
These are instructions from Harlan's write up (edited - non-nitrous set-up):
There are 3 parts to the wiring harness:
Coil pack connections (large bundles terminated with connectors)
Activation inputs (long whie and gray wires)
Relay output (short yellow wire)
COIL PACK CONNECTORS
The coil pack connections are made by intercepting the PCM control signals at the large gray connector in the center of each coil pack. The harness has 2 pairs of connectors - one pair for each pack. Unplug the connectors on both coil packs and jumper them using the paired connectors of the 2-step. Either connector pair may be used on either engine bank.
ACTIVATION INPUTS
On/Off Operation
This allows the user to activate and de-active the 2-step mannually.
White wire (arming Switch): Momentary switch to ground
Gray wire: Connect to ground or parallel with white wire
Latched Operation:
White wire (Arming Switch): Momentary switch to ground (I put a switch attached to the shift lever for easy reach)
Gray wire (Hold Switch): clutch pedal switch -- this is where the 1998's are different - there is no computer connection - So I used the cruise control switch (located under the panel right by the clutch) just disconnected my cruise and wired in the gray wire.
YELLOW WIRE: Is used for nitrous set-up - I won't go into it as it is long.
After you get it wired for Latched Operations:
Set the desired RPM launch by turning the dials to desire #, set both to 0 "deactivates" the system
Push in the clutch
Press the momentary switch and release it
Keep clutch pushed in
Bring up your RPM's (floor the sucker)
It should hold at the set RPM's
Release the clutch - which de-activates the 2-step and your off
Or Manual mode:
Set 2-step RPM's
Press in clutch
Hold switch
Release both clutch and switch -- this is very hard to time and would strongly suggest using the latch operation.
One last thing that Harlan stated and I will re-state - You are using this product at your own risk.. Also DO NOT USE THIS DEVICE ON VEHICLES EQUIPT WITH CATALYTIC CONVERTERS
Hope this helps

Re: Need directions for harlan two step ibought a mini momentary switch from radio shack and mounted it to some bracket down there so my lutch pedal nudges the switch closed when pushed down. i also installed a 'arm' led also from radio shack that indicates when the 2 step is active.
