Im confused on how to diode isolate 2 (+) parking light output wires. one coming from aftermarket alarm and one coming from remote starter. I also need to connect them on a SPDT relay. Thanks in advance

I need more specfics. What alarm/remote start. What vehicle. And typically a diode isn't needed if using a relay.

You don't have to. Just join making sure they polarity is the same, if the vehicle spec calls for NEG (-) make sure they're both neg, ditto for POS (+).

Amateurs assume, don't test and have problems; pros test first. I am not a free install service.

Thanks for response. Do i need to tap in from the alarm or remote starter's output wire? or tap in to the SPDT relay's wire? Im just gonna use a squeeze tap connector.

One more thing, will it break if I use both the negative and positive parking light wires? right now im using the negative for the alarm.

thanks again

Show us your circuit, I don't understand the question.
Squeeze tap?
Forget it; just wrong in so many ways.
