yes, the price of $200 is a little high for a standalone remote start
unit with detailed instructions and a plug-n-play harness. from
the images posted the owner still needs to wire up the additional
safety checks ie. hood, brake etc... from my previous installs they
don't appear to be 'plug-n-play'.
for $70 you can purchase the dei 561t which includes the rear
defroster output and for another $25+ you can buy a turbo timer
harness and some crimps to make it 'plug-n-play' and you can still
use your factory remote as well!
also, the dei's install manual can be easily found on dei's site here.
the wiring for the scoobies can be found in this forum as well.
the only thing i'd see is trying to locate the proper activation
circuit to activate the remote start. i suspect 1 of the 3 wires
located between the keyless entry system and the security
harness can be used or wiring it up to your door lock
wire and program it for 2 pulses for remote start activation via the
keyless entry remote.
another key feature to have is the 'anti-grind' feature which
prevents the starter motor from cranking when the owner
accidentally turns the key to 'start' while the vehicle is remote
started. and though not advised you can easily integrate this
system with a manual transmission.
just an alternative option.
