relay remote start 97 wrangler

Before I get any hassle, let me give a little background. I am a Electrical Engineering Technology student at Purdue University. I am doing a senior design project to control my winch for my jeep from my iphone. One of the features is to remote start the car when the battery voltage is too low. I cannot just buy a module for remote start, that defeats the purpose of my senior DESIGN project. I found a schematic for a relay remote start Here. The wiring for my vehicle is Here. The part I am unsure of is that the relay diagram has 2 accessory wires and only one ignition wire. The wiring of my jeep has 2 ignition wires and only 1 accessory wire. I don't know enough about remote start systems and the wiring of my jeep to mess around with it. I would appreciate any and all help. Thanks

link above was a remote start using 4 relays.

if you need additional ignition circuits, they can be simply wired in by using the existing trigger.

with an extra relay

85 - ground or switched ground source if available.

86 - ignition output from relay87 - constant 12v30 - to secondary ignition wire.

fuse everything accordingly.

Heres a diagram of adding additional relays to a circuit...Instead of remote lead it would be ignition... Same as tedmond said...just a visual...

Connecting Additional Devices to the Remote Turn On Wire ( link)

Using a 30 amp SPDT relay, connect terminal #87 to constant 12 volts positive with a fuse rated to the sum of the additional accessories you've added and the components you need to turn on. (If you have two fans rated at 5 amps each and a neon light rated at 10 amps, you would use a 20 amp fuse plus 200 ma for each amplifier and processor.) Connect terminal #85 to ground, terminal #86 to the remote turn on wire from the head unit, and terminal #30 to each accessory with an appropriate fuse. A fuse (not shown) could also be used between the output of the relay (#30) and the remote turn on wire of the amplifiers and/or processors for extra precaution.
