Subject: 08 f350, keyless, strange problem
Date Posted: October 15, 2008 at 5:19 PM

I am installing a keyless system in my 08 Ford F350. Real basic. It currently has power locks but does not have keyless. So I hook my wires up and just do a jump to the power lock and power unlock wires (from what I read). I hit the unlock button and I can hear the relay in the brain work but it does not unlock the truck. Same with the lock. Thats my first problem. Which lock system do I have? I thought I had the 3 wire negative but maybe not. The real problem is very strange. My parking lights will not go off. Real weird. I have everything disconnected from the brain and they still stay on. The only way I can get them off is if I ground the parking light wire, or if I disconnect the batteries. wth? I don't get it. What the hell did I do? Please help me here. Thanks.

boulderbronco, when you use the switch, do the locks work? but they do nothing with the transmitter?

You mean the factory lock/unlock button? Yeah. It works fine. But using the transmitter it does not. The big problem I have is not being able to get my parking lights off. That and apparently I am hooked into the wrong lock and unlock wires. Or I have a different locking system. Like the "5 wire reversal rest at ground."

The switch is no good now....Did you have autolites(autolights)? I know a guy that wired at the switch and had the same problem....The fix is to get the lights at the kick panel WHITE/ purple I think..... But the switch will need to be replaced...Or atleast thats what ford told us...

Thanks guys. I do not have DRL (daytime running lights) or autolights. I am currently hooked into the WHITE/ violet wire as that is the one that tested right. Strange though as this list says a different wire. So you think I toasted my headlight switch? Makes sense I guess. But if thats the case, and I have the right wire, how am I suposed to hook up my parking lights? I have it hooked to the WHITE/ violet about 12" from the switch itself. Am I suposed to tap into it after a junction or relay or something?

ckeeler,

So your saying I don't have the 3 wire negative I have the 5 wire reversal? That means I need a relay setup according to my manual. By the way I am installing an Omega REC-11+.

Thanks again guys for your help. Here is what I found on this site for wiring for my truck.

Here is what Audiovox lists for the 08 F350:

If your lights are still staying on, There is a burnt trace inside the switch body itself. Remove the switch, remove the 3 screws on the back of the switch, remove the case of the switch. There is a very small trace on the board that has burnt open. Simply solder a small wire from the next component left of the burn, solder the other end of the wire to the next component right of the burn.

You asked "What did I do", for all of these things that I have repaired so far, the installers all said the same thing, I looked at the computer for the wire colors but I forgot to check the polarity. So if I had to guess, you used the wrong polarity when you connected to the wire at the switch.

Right. I'm trying that fix but with .050" solder and a rather large iron it's a tough do. But that is definatly the problem. Now my manual says the wire should still work with a (-) polarity signal switch. It says "Some vehicles...triggered by a Negative Ground circuit from the headlight switch. These cars can still be coonnected directly to the White wire by finding the parking light circuit after the relay, usually at the Fuse/Junction Block." So I take that to mean I should basically hook my wire to the back of the light itself. Also if you look at that wiring list I posted it says the parking lights are Blue/Gray (-) at the headlight switch. There is no Blue/Gray wire there. Below that it says low Crr. PK lights (+) drivers kick panel. That is the one I am connected to (it actuall comes right off the switch. Anyway thanks for the help. I'll just run my wire into the engine bay and hook to the wire directly at the parking light and just get a new headlight switch.

But now what do I do about my locks?

I'm not sure what those tech notes are talking about. I've done multiple 08s that were not equiped with factory keyless. The wires will be blue/green and yellow/violet(-) in drivers kick. You need to test because there are a couple of each of that colors. For the parklights I use violet/white (+) In the Drivers kick..not at the switch

Thats how I have the locks hooked up. I jumped in at the door grommet just to check and it didn't work. If there are multiple of those colors I supose I could have the wrong ones. But I didn't think manufacturers ever, ever put the same coded wire in the same harness. So your saying the 08 F350 without keyless has a 3 wire negative pulse system? Thats what I was thinking it had. I'll look into the multiple coded wire issue tomorrow. As for the parking lights I just hooked into the wire right behind the headlight.

Ive never done a five wire in an 08 superduty and I've done quite a few. There are multiples of the same color in the drivers kick..... How come you're not using a multimeter to test wires.......sort of risky working on that new of a vehicle without testing your wires first, not to mention wasting time to diagnose what's happening.

Must be a 3 wire system. I am using a multimeter but I did not use it on the lock and unlock wires because the chart I had (posted earlier) stated the color of the wires and I found them in the door harness. When I am under the dash I probe every wire even if I have a diagram. Don't want to trip the air bag. I'll give it a shot tomorrow. Man I can't wait to have a full size garage.

no, you do not have a five wire system......so, after your tired of messing with them and they still dont work........ wire them up like a 5 wire setup then get with me from there.

no, you do not have a five wire system......so, after your tired of messing with them and they still dont work........ wire them up like a 5 wire setup then get with me from there.

Thanks for the help but I am not an expert at this stuff altough I have installd a few remote starters in the past. You said "after your tired of messing with them and they still don't work... wire them up like a 5 wire. I don't get it? Your saying I have the three wire setup but to wire them like a five wire? Why tell me to keep messing with it if you know what the problem is. The manual I have it says I have to have relays and other devices to wire a 5 wire setup. My manual says I would need the optional DLS & SPDT relays. Again I am installing an Omega REC-11+. You are saying I can not wire it like a normal 5 wire? Just trying to clear it up. Also I need your help now not after the five wire. I need to know how to wire it up. After that I am done. The remote start is easy.

Well I do appreciate the help. But like I said the only problem I HAD was figuring out the wiring of the locks. After that I was done, there was no "rest." That is what I needed help with. In any case I got it working. I must have had a bad conection yesterday as it works great just taping into the lock and unlock wires. Thanks again.
