Hey there. I have a problem and I hope you fellow 12 volters can help. I wanted my headlights to flash with my parking lights when i armed/disarmed my alarm. So i took 2 SPDT relays and i wired them as followed.....
85- to the parking light output wire its +
86- ground
30- to 12v fused constant power
87- to parking light wire (have it hooked up to blue wire) although i know that their is two wires and locations for the parking lights
- to headlight wire (RED / blue)
Keep in mind that the pin configuration for 86,85, and 30 are all the same on both relays. on one relay i have 87 going to the parking light wire and on the other relay i have 87 going to the headlight wire. I listed what wires i used above.
Now that I've done that when i arm/disarm my alarm nothing works. My parking lights don't flash anymore. everything else still works like regular like my headlights and parking lights. They just don't work when i arm and disarm my alarm. I haven't troubleshooted my wiring because it got dark outside. Maybe its something little that I'm overlooking or a wrong pin configuration on my relays. Any help would be greatly appreciated!!!!
Also is their a better way of wiring this scenario to have my headlights flash with my parking lights. If so please lend some help lol. Thanks a bunch guys

Some relays have built in diodes-I would switch the wires you have on 85. and 86.Put 12v(p.light output from alarm)on 86 and ground on 85.assuming your unit is providing 12v for the p.light output.
What year, make, and model is your car?

its a 2003 honda civic hx. Thats what i was thinking was to switch around pins 85 and 86. I know that their interchangeable but I was going to try that and see what I got. Ill try some things and let you guys know.
