Blowing trunk output?

Ok. Let's try this again.

Here is an interesting cause and effect but I'm not quite following your thoughts. If I understand you, the car would turn the +12 off, for example through the battery saver relay, thus making the cathode more negative than the anode. The remote would then go to ground through the trunk output thus pulling too much current through the base and blowing the output transistor in the process. Hum!. Food for thoughts here. Only thing is, the first module didn't have the diode across the coil. i only added it because I thought that the coil field collapsing was the culprit.

Surely my setup is not that different than what many others would do. There are also 100's of Taurus out there so someone else should have seen this problem right?

Is this the wiring setup you're talking about?

I'll be getting a new module on Wednesday and I'm planning on changing the wiring to this.

This way the remote output will be isolated from the trunk circuit.

Thanks JWorm,

The setup you suggest is really the same as I'm picturing above. The diode is already on the relay and it won't hurt anything other than polarise the coil's input. Will it?
