digital rpm activated window switch pn 8969 parts included: 1 - digital window switch, pn 8969 1 - parts bag operation the msd digital rpm activated window switch accepts a variety of input signals from sources such as a coil negative terminal (factory inductive ignitions), a cd ignition tach-output such as an msd 6 or 7 series ignition, an output from an ecu, or a 5-400 volt signal from an msd tach adapter. the pn 8969 can be programmed for use on nearly every engine with a spark ignition or tachometer signal. the rpm values are adjustable in 100 rpm increments from 200 - 15,000 rpm (the rpm is shown x100). there must be a difference of at least 300 rpm between the two activation points for correct operation. changes can be made while the engine is running. note: there is a 200 rpm safety range built into the activation and deactivation points. this means that the rpm must drop 200 rpm below the activation point to turn the circuit off. conversely, the rpm must drop 200 rpm below the deactivation point in order to turn the circuit back on. this is to prevent the circuit from chattering on and off. this switch is also capable of activating a circuit at a higher rpm than the off rpm. programming the rpm the engine application and rpm activation points are easily selected through push buttons on the led panel (figure 1). this switch can be programmed for a variety of engine and ignitions as shown in the following chart. 1-cylinder this program is used for individual coil per cylinder systems (such as gm ls-1 engines, or 99-up mustangs). 2-cylinder this is for ignitions with coil packs that fre two cylinders at the same time (waste spark systems). 2-cyl. odd use on coil pack ignitions that are on odd-fre engines such as a viper v-10 or harley-davidson motorcycle. 4-cylinder typical 4-cylinder engines with a distributor. 6-cylinder typical 6-cylinder engines with a distributor. 6-cyl. odd typical 6-cylinder odd-fre engines with a distributor. 8-cylinder typical 8-cylinder engines with a distributor. m s d ? ? ? w w w . m s d p e r f o r m a n c e . c o m ? ? ?
