I know there are already some posts in this forum regarding this, however after reading them and attempting to access suggested links in them, I'm thoroughly confused and not sure if I've found the right answer.

I hooked up an alarm system on a 2001 Tib and everything is functioning great except for the parking lights flashing when the alarm is activated or deactivated. After testing the wires coming from the wiring harness of the multi-function switch several times. I connected the wire from the brain to the wire from the harness which tested positive as the parking lights wire, however after testing the alarm I discovered this wire (blue/black) is actually connected to the low head lights. I don't mind them being the ones that flash, however only the head lights flash not the head lights and tail lights. Also, there's a fuse (15 amp) off the brain which apparently is involved in this connection and it has blown once. Not sure if it blowing has anything to do with the connection to the head lights instead of the tail lights, but I would like to get this configured correctly. What I hope to hear from someone is the color of the wire coming from multi-function switch wire harness to the parking lights on a 2001.

Any and all help is greatly appreciated. Thanks.

 

me thinks you will need a relay. your alarm probably has a pules output for the parking lights, but cannot supply the current necessary to drive them. this is where a relay would be needed. it allows the low power output on the alarm to drive a much higher powered component.

any details on the alarm? type/brand/online manual?

 

Sorry about that, tried to include as much detail as possible and forgot the info on the alarm.

AUDIOVOX AX510
From the link below click on the PDF file for the APS510 Installation Manual. The wiring diagram of the alarm brain is on page 8.

ok, i checked it out.

your problem is that you need a pulsing ground, not a pulsing power. if you know how to read shcematics, go to the diy section, and in the "stickied" section, use the universal webtech login to get into webtech. then hit service information in the upper left-hand corner. find the parking light schematic and check it out.

anyway, you will need to do the following. pick up a bosch relay from an automotive store. connect the pulsing power wire from your alarm to relay leg #85 and ground to leg #86. if the relay you get isnt already diode isolated(probably wont be), pick up a 1N4001 diode and run it from leg #85 to #86. the band on the diode should be "pointing" to the power leg, which is number 85.

run wire off of the red wire running into the multifunction switch that shows power at all times. connect that wire to leg#87a. connect leg #30 to ground. leave 87 alone.

 

Thanks for the info, greatly appreciated. Going to get the relay tomorrow and give it a shot. Thanks again.

 

np man, tell me how it works out.

 

it would probably be easiest to just tap into the wire coming from one of the switches in your dash.
they are all illuminated when the parking lights are turned on, this is how my alarm was on the blue tib.

 

actually, you could do that using the hazard switch.

connect the pulsed + output to the green/white and green wires coming out of the hazard switch. make sure you get the thicker wires. the thinner ones are for illuminations. you should be fine on current.

 

any switch harness.
dimmer, fogs, cruise, hazard..

i'd probably use the dimmer switch, because then you don't have to take the main dash off, just the crash panel, radio/shifter surround. less screws tongue.gif

 

i think that would work, but i wouldnt trust the illumination wires for that extra current. they are super skinny. it would be the green/white wires though if you wanted to try it.
