Got it sorted. Thanks to Dimitris!
My car is a late model 03 and apparently there was a change in mid 03 as to how the main relay is activated. I'm pasting Dimitris' email below. BTW I'm totally blown away with Dimitris' knowledge and support, I purchased this MS2 from another forum member and Dimitris has still answered my questions. Top notch customer service!
That explains it. On the 01-03, the main relay is activated by the ignition switch.
On the 03+, it is activated by the ECU itself. If the ECU is order for a 03+, I install a circuit inside the ECU to activate the relay.
However, you can wire in an additional relay on the wiring harness, which will activate the main relay.
You will need a standard 4-pole automotive relay, which has the 85, 86, 87, 30 contacts labelled.
Connect 85 to pin 4S on the harness.
Connect 86 to 4A
Connect 87 to 3H
Connect 30 to 4A
This will activate the main relay as soon as you switch the ignition on.
