The factory A/C controls no longer had a purpose since all of that hardware had been long gone. There's no sense letting all of that stuff go to waste, so the controls were given new functions. The fan swich controls the cooling system which incorporates a "TIK-TOK" box that switches the cooling back and forth between the fan and water pump. This feature can be used for both cooling down efficiently after a run, or warming the engine up as a thermostatic switch is employed to turn both on when temperature gets to 160 F or so.
The lower slider controls the line lock and transbrake functions. There is a tiny button on the end of the column shifter. When the lower slider in at the "COOL" position, the button controls the line-lock. At the "HOT" position, it controls the transbrake. The upper slider has only one purpose. At the "MAX" position, both stages of nitrous are activated at the same time.
The buttons on the radio can play too. A bracket was fabricated to house miniature push-button switches. The one on the far right closest to the cigarette lighter is depressed at the same time as the cigarette lighter to purge through the engine. The next one arms the future installed F.A.S.T systems data logger, and the one at the left turns on the bottle heater. Two places are empty for now. That's not too hard to remember is it?
Below are some photos of some of the electronic features of the Sleeper "HEAVY CHEVY". It may seem extravagent but the system is based on logic which makes it a lot easier to remember. Complicated? Maybe. You be the judge. If it's too complicated for the owner he can always print these pages out and put them in the glove box with the gages!
The factory wiring harness had to be "re-engineered" to get rid of circuits that weren't being used. Todd McCutchen of "Quick Classics" in Atoka, TN came over to lend some OEM expertise. We powered up the system by hooking the hot and ground leads to a battery and checked to make sure everthing was in working order.
Think the factory AM radio is useless? This one will play you to "SLEEP". The station display area houses functioning display lights. Indicator lights for the transbrake, water pump, fan, nitrous armed, and future F.A.S.T. data logger are there. The OEM generator light (GEN) beneath the speedometer indicates that the bottle heater is turned on. TEMP and OIL serve as they were intended from the factory. BRAKE light has a purposes of both, Wilwood emergency brake and line lock. The radio On-Off/Volume knob arms the nitrous when it's turned on. When this occurs the horn button at the steering wheel becomes the source for second stage nitrous activation. If the radio is turned off, the horn is a horn. The nitrous can not come on unless full throttle is activated.
The back and side of the A/C unit houses the TIK-TOK Box mentioned above and necessary relays in order to have the "sleeper" functions. It's all self contained and plugs/unplugs for easy installation/removal.
