Ok, I'm *trying* to install Keyless entry on my truck. But, I got this big jumble of wires, lol .

So, I need the following Locations and/or Colors of wires.
-The '+' For Parking Lights. (In dash somewhere?)
-Wires For Power Lock Switch (what color?)
-The '-' For Horn Switch (steering column?)
-Switched +12V Ignition Wire (steering column?) (must be 0v at key OFF or ACC)

If anyone can lead me in the right direction, I'd really appreciate it.

I wanna try it myself before taking it somewhere. Thanks

 

If you look through the wiring diagrams in the back of the Haynes manual for '80-'96 trucks, you'll find the wiring paths and colors you're looking for. Get your reading glasses or a magnifying glass to help see it and a pointer to help follow the paths if you're eyes are getting tired like mine are.

 

Oh, a wiring diagram can be found in one of those books? Great.

lol, my eyes are still good. I'm still a young guy in High school. .

 

The folks that install these things have a book that gives highly specific wire color and location info broken down by year/make/model. This makes it possible for them to tap into the correct wires AND find a convenient location to do it, so that the alarm system wires do not have to be run all over the truck. The books even include directions on dash disassembly and suggest where to put the various components.

At least one vendor (Avital) used to have this online, but it's not there anymore. Perhaps if you searched online, you could find some vendor or other that has it available.


I can give you wire colors, but they are for my 1991 F150. They may have changed in the interim. I can't help you much with finding the "best" place to tap these wires. Remember that this info is worth what you paid for it -- I got it from my alldatadiy.com subscription specific to my 1991 truck.

Door lock motor: Pink with orange stripe = +12 volts to lock, ground to unlock
Pink with black stripe = Ground to lock, +12 volts to unlock
Try the area behind the driver side kick panel

Parking lamps: Brown
This wire runs all over the place. The wire color is an unofficial semi- standard across automakers. Try tapping it near the light switch.

Horn: Dark Blue
If you have cruise control, then you ground the dark blue wire to energize the horn relay and thence the horn.
If you do not have cruise control, then you don't have a horn relay and you connect 12 volts to the dark blue wire to energize the horn.
I'd look near where the wires exit the steering column. There may be two dark blue wires, you need to figure out which wire is the "Input" to the horn switch.

+12 volts. If you really want "hot in run", then go for pink and orange wire off fuse 5
If you want "hot in run or start", then go for the red and yellow wire off fuse 18

 

Nice, once again fefarms, you came through!

Those wires are the same as mine. When I looked at the power locks, sure enough there was pink/orange, pink/black. So, Im guessing all the other ones are the same.
Thanks, I'll post back and see if I got it right .

 

just keep in mind that Ford uses a reverse polarity setup. So if your keyless entry unit does not have the built in relays to control this, you will need to buy 2 5pin relays to wire it in.

As for wiring diagrams, you can always use www.bulldogsecurity.com , they have pretty much every vehicle there and gives you a color and area to get to the wire.

Niiiiice, thanks. Since I worked today, this is definetly getting done tomorrow.

 

Arhg, installing it today and when trying it out, It wont lock/unlock!!

Everything else works, horn, lights.

What is this 'Reverse Polarity'? Could tis be causing the problem?

 

Yes, evidently the standard alarm systems are set up to work with OEM supplied relays. Systems like the F150, where there are no relays, need external relays added.

A discussion of the various door lock sytstems can be found here:
http://www.deannet.com/egd/e_cs2015fm.htm

The Audiovox manual should have gone into this...

 

Hmm, more mind-jumbling wiring ahead

Apparently I missed the Wiring options in the manual. I don't really know about relays, but it looks like I need 2. Where and what kind should I get?

 

Do a yahoo search on "automotive relays". One informative site is this one:
http://www.wrenchjock.net/automotive_electronics.htm

The place you bought the alarm should sell suitable relays. They should only cost $8 to $12 each. You need 5 pin relays, with an "87" Normally open contact and an "87a" normally closed contact. 30 amp relays are probably the best choice, though the current rating is overkill, these are the most common and probably cheapest. Get a couple of sockets to go with them.

Alternative sources include Digikey or Mouser or Radio Shack or scrounging in the junk yard.

 

Would those specifications be the same for my 95 F150? According to the link to bulldogsecurity.com it is the same.

 

According to bulldog, Ford trucks right up through 2000 use type C locks, unless they have factory keyless entry.

You may or may not need relays. It depends on the system you are installing. Look at the manual. Some have built-in support for Types A, B, and C. The ones bulldog sells do not need external relays, for example.

www.directwholesale.net sells suitable 30 amp SPDT relays for $3.99 in their "accessories" section.
