Cold cranking wire? on a remote starter?

I am trying to install a remote start alarm into a 1990 300ZX.   I have a question on how cold cranking works...  One thing that makes things difficult is the DEI wiring diagram is slightly different from my harness.  I will illustrate both below....

My 300ZX has your typical ignition setup with one exception

Here is also a schematic from the 300ZX online manual.....

Here is DEI's chart

Notice that DEI shows a second starter..... and 2 black yellow wires... 

I found through searching that this is probably a second starter wire.  When connecting this would I use a relay? 

Also this is a Lynx 2000 alarm.  Which is real close to a crimestopper alarm.  They both have the manual safe remote start...

Yes, you can hook it up directly with the other starter wire, but like chris stated, it's best to use a N.O. relay triggered with the Ign 3 wire from your remote starter.  This wire does directly go to the starter solenoid, but the car's ignition system only uses it when it is cold, so using a relay would avoid the wire being energized in uneeded conditions, like when you start your car with the key in the summer.
