Just remove R1, R5, Q1, and R2. Connect directly to pin 9&10 and pin 9, 10 need resistor 3.9K to ground. Work nice trust me I spend to much time with this.

Couldn't find what Vcc was in *this* circuit, but I'll re-work generic values for 12 Volts ( Lead-acid 10--15 ;-) anyway... Hmm: I'd add a 5v6 zener Gate / Source, but I'm paranoid.
