and I tried this on Carnetix with no luck, but here goes:

Hey all,
After having the 2140 installed by a pro car audio place, who has done one of these before, I get 5 flashes then the 2140 does not respond. Fan never goes on. Mac Mini 1.66 Core Duo never comes on.
A few basics:

-JP1 Set to 18.5 for Intel Mac Mini
-JP2 set to 12V - eventually will be used for display (current display is USB Mimo 710
-JP3 is set to default
-JP4 is set to Config 2, PriOut
-JP5 is set to Mac Mini Intel, of course
-JP6 set to ACPI Relay Output, or default.

-SD_DLY 0 min, 22 sec
-DMT 50 hrs
-DLYON 3 sec
-BU_LO 45 sec
-SD_LO 45 sec
-LO_BAT 10.1v
-Standby Hibernate set to Standby
-Turn ON set to Ignition
-Turn OFF set to Primary Out
-Fan set to Enable
-ACPI Delay and Duration set to 10.0 sec

Any advice would be greatly appeciated. Y-Cable is installed. Mac powers on with normal power brick by pressing power button, even with Y-cable installed. Car is a 1970 Mustang. Shop confirms that power is good to the input, and should work under Accessory or normal driving mode.

Any ideas?
