Need help with Harlan 2-step I just received my Harlan 2-step. After reading through the directions I'm a little confused on how to connect everthing together.
I want to activate the 2-step with my t-brake button. I also want to de-activate the NOS at the same time so I can leave the line at WOT.
On/Off operation:
On/Off operation allows the user to activate and de-activate the 2-step manually.
White wire (arming switch): Momentary switch to ground. Normally open, close to activate.
Gray Wire: Connect to ground or parallel with white wire.
Relay control output:
The relay outout provides a switched ground (yellow wire) whenever the 2-step is armed or active. This can be used to deactivate a nitrous system that normally uses a wide open throttle switch for activation of the nitrous, or for an indicator that the 2-step is active.
I am not very electrically inclined so I would greatly appreciate some help.
The way I read it is I will tie in the white wire between the t-brake button and the t-brake silinoid. The gray wire will simply go to ground.
The yellow wire will tie in between the relay and the nitrous WOT switch.
Does that sound about right?
TIA

Re: Need help with Harlan 2-step Yep.
I am not sure on the trans-brake, but sounds right. As long as you hold in the switch the 2-step is activated. Release switch and it disengages the 2-step.
Gray is purely a ground to any where.
Yellow is the key to activate/deactivate the nitrous system. I followed the direction from Harlan as best I could - I am also electronically dense. I also have my window switch connected in with the same relay - 2 separate relays. It does work great. Push in clutch, set 2-step, slam the gas to the floor, release clutch, launch at 5800 rpms
