Can you tell me or direct me to a drawing how to isolate doors with diodes? I prefer to do things in a proper way.

Is the drawing on the left applicable to my car door triggers? https://www.the12volt.com/diodes/diodes.asp

Actually on these Mr I is right Look at your gauges. With the ignition on you should have one warning light each for both trunk/hatch open and door(s) open. remove the gauge cluster (very easy, 2 screws and pull out the binnacle, then either 2 or 4 screws to remove the cluster). With a DMM see which two wires go to ground when either ANY door OR the trunk/hatch are opened. Your green and blue wires go to each of these respectively, no problems with dome light delays and you won't need dome supervision And look once the gauges are out how much room there is to loose the alarm up there.

Not needed on this vehicle there's one instant on/off switched line for all doors and trunk to rear of instrument panel.

Sorry, I meant to say one each for doors and trunk/hatch.

So I don't need the diodes, correct? Thanks for all your help.

Not on this vehicle

OK. Thanks. One more connection I'd like to make to the dome light. The manual said I need a relay to do this. Where can I buy this? Or is it a DIY thing?

You won't need it. Notice how when you close the door your dome light stays on for about one minute or until you lock it? That's built-in dome light supervision so it isn't needed
