diode isolate parking lights 89 vw jetta

I'm intalling an alarm in my 89 Jetta GLI and I'm wondering which would be the proper way to isolate the parking light switch with a diode. I have one output which sends +12v to the parking lights when the switch is in the right position. I need to tap the parking light flash output into that wire. Which is the proper way? Figure 1 - diode inline with parking light wire Figure 2 - diode inline with alarm trigger wire I want to do it the proper way and not backfeed any voltage where it doesn't need to go. Thanks!

figure 2There are 10 types of people in the world, ones that understand binary and ones that dont.

Perfect, thanks!

actually both ways work, the first way will also isolate it from the switch, if the diagram wants the lights used to isolate from the swith use the first, if they want it to isolate from left and right use the second. hope that helps, i read your post wrong at firstThere are 10 types of people in the world, ones that understand binary and ones that dont.

Weird thing is, all the online resources and manuals say there are dual lighting circuits, and the car has two parking light fuses, so there *are* dual lighting circuits, but they split at the fusebox after they exit the light switch, so at the switch there is only one pin to worry about. Lights all six. Got it hooked up last night and it seems to work great. It immediately goes off when I reconnect the battery, which is weird, but I'll sort that out later. Thanks for the help!
