viper 5706v in 90 land cruiser with chevy motor

Hi i am looking for some guidance i am attempting to install a viper 5706v unit into my friends 1990 toyota fj62 with a Chevy vortec 5.3l in it. The only part that is confusing is the 10pin rs harness. The toyota ignition switch uses 2 start wires. But when testing it i found that the truck will run and start. With one of the cut. Any guidance as far as which connections on the 10 pin are required would be helpful. Thank you

Two answers here, either the Chevy engine doesn't need it or you will need that second starter in the winter. With a relay, wire thus:- H2/21 violet / YELLOW to 85. Ign. to 86 Constant fused 20 amps to 87 30 to second starter. Diode, 1N4004 across coil, 85 and 86, band side to 86.
