What's the SECU? Is this just the ECM? Also, what are the notes, the links don't work right.

SECU is the smart entrance control unit that controls door switches, locks and interior lights and is located to the right of the steering column. The ECM is under the console near the heater.

What notes are you looking for?

The note for the door trigger and the note for the tachometer. Is there something important other than check the tach for ac instead of dc? Thanks for the help.

Door trigger...

Notes: Vehicles without power door locks, the door trigger/dome light is RED / black in the driver kick, harness to rear.

Vehicles with power door locks, the driver door is GREEN/ red at the SECU, pin 1, the front passenger door is GREEN/ black at the SECU, pin 2, and the rear doors are RED / black at the SECU, pin 3. Use all three wires and diode isolate each.

Tachometer...

Notes: The ECM is located below the heater box to the right of the accelerator pedal, behind trim panel. The tach is in the top row, 2nd pin left of center of the plug.

Not sure if you're doing locks but my advice is to use single lock relay set up and tie in to the following wires..

Power Lock	lt. GREEN/ red	-	SECU to right of column, pin 5
Power Unlock	brown	-	SECU to right of column, pin 4

Let me know if you have questions.
