I'm selling my heater core bypass set up for use with LS engines (never used). This is the Old Air Products 50-1555. I converted this control to be used by a toggle on/off switch instead of a rotary switch. Mine can also be used with no switch at all for stealth operation. You would just tap in to the "AC on" power supply. When you turn the Air conditioning on this would automatically close the valve to by pass the heater core. One less switch to install. $80 plus shipping. SOLD
