Your Viper 5901 comes factory set for 2 IGN outputs via its flex relay. You will need an additional SPDT 30 A
relay for the second ACC output your truck needs.

At H3, you will connect H3/1 to the trucks IGN1.
H3/2 connect to +12v constant power (for flex relay).
H3/3 is ACC1 and goes to the trucks ACC1.
H3/4 is Start1 output.
H3/5 is Start1 input.
H3/6 connect to +12v constant.
H3/7 is IGN2 and goes to the trucks IGN2.
H3/8 is not used.
H3/9 connect to +12v constant.

On the Remote Start AUX output 5 pin connector you will use the Orange wire at pin 2 to control the
extra relay and provide ACC2. Wire the SPDT 30A relay as follows.
Pin 85 to R/S AUX 5 Pin connector, pin2, Orange wire.
Pin 86 and Pin 87 to +12v constant fused at 30 amps.
Pin 30 goes to trucks ACC2 wire.
Pin 87A is not used and should be cut and properly insulated.

There is a Viper 5901 install guide in the Downloads section of this site for additional info.
