I have a new 2009 F150 Platinum. Just put in the factory Ford/Code Systems alarm with remote start, the 6-button fob version. I would like to hook up the defrost and heated seats to my system, but people say I can't because of the module network on these trucks?

Ford's diagram didn't show this, but I have the DEI wiring diagram that identifies the defrost and heated seat wires at the SJB (smart junction box). Can I hook up the AUX wires on my Ford system to those wires or not?

thanks...

looks like there is a WHITE/ orange wire that comes from your EATC head the controls the rear defrost relay. I would pull out the EATC head and grab it there because it should be easy to get to as the defrost relay is in the battery junction box not the smart junction box. Its a ground pulse wire, you would need to test for a pulse or latched activation. That system has both options in the programming menu if its the ford power code theres a blue/white wire on the C-Harness that is for the rear defrost it uses the blue start button to turn the function on and off after the truck starts you can hit that button again and it will turn that feature on and off

As far as the heated seats go im not seeing much you can tie into with that system as its mostly MS CAN run

The rear defrost is latched.

thanks the replies.

Yes it is the Powercode system, I'm familiar how it works (how to turn on the defrost). Yes, the AUX wires are on the C-harness. C-11 is AUX2/defrost, a blue/white wire like you said. C-10 is the AUX1 and it says C-2 is the AUX3

Now I see I misread the DEI wiring info, it does say these wires are on the HVAC plug, not at the SJB. Defrost is WHITE/ orange with a - latched polarity. Left heated seat is a WHITE/ blue wire with - polarity. and right heated seat is gray / YELLOW with - polarity.

So I couldn't grab those heated seat wires and hook them up to the other AUX wires on the C-harness?

i see the two wires you are talking about they are the request wires that go from the HVAC head the the heated seat module im not sure how the seats will act using those wires

ok, maybe won't mess with them then, don't want to fry anything.

but you think I could hook up the defrost wire with no problems?

just stinks that I have these extra 1 and 2 buttons on my fob and can't really use them on anything. Somebody else told me that a Ford databus interface is in the works (aftermarket) that will help with tie in the heated seats, etc., but it probably won't work with the Ford rmst.

i dont see an issue hooking the rear defrost up make sure you test first

im not sure about the aftermarket interface

Good luck Joe

well, I think I'm not going to mess with any of those options, don't want to fry anything.

But I came up with a new idea for an option. My truck does have the power folding mirrors. Could I hook up the C-10 AUX 1 wire from my Powercode alarm to the mirrors? I don't want the mirrors to fold every time I arm or disarm the alarm, rather I just want to hit the 1 aux button on my fob to fold in the mirrors in or out when I want to.

I got the mirror wiring diagram from the Ford service manual. It identifies the fold wire coming from the switch, and also identfies the fold out and fold in wires at the relay module (driver seat module/DSM).

Do you think I could get this to work and how many relays would it take? Anyone else have experience with the Ford power folding mirrors?

looks like FOLD OUT is GREEN/ violet and FOLD IN is violet/brown at the DSM you should be able to use 2 relays 1 for each side and 5 wire them

87 to power
86 to power
85 to ground out aux signal from remote
30 to the mirror side of cut wire
87A to module side of cut wire

do this on both wires

use RED / white and the BLACK/ green from the C- harness and set them to time held or you would need to set up some sort of timer circuit

Thanks Joe. So both mirrors would fold with button 1 on the remote? Also, would my factory mirror switch still work/still fold the mirrors too?

also, do I need to convert the the AUX 1 headlight output to the power sliding door output in the programming option bank 5?

your factory switch would still work and you would need to use both channels one for fold in and the other for fold out yes you would need to change from headlight to sliding door

hey Joe, I sent you an email earlier today, not sure if you got it. I was just curious, wouldn't there be a simpler way to hook up the AUX channel to the mirrors by using just the gray/brown folding wire coming from the mirror switch and then let the existing Ford relay module do all the work as far as folding the mirrors?

Steve

i see the gray/brown you are talking about im not sure on that wire as i dont have a truck to test it it looks like that wire sees ground and the yellow/orange sees power when the fold button is pressed test it first let us know how you make out

ok, I'll try this weekend maybe.

I just got that idea because I was looking at the optional connections on the 08 Expedition/Navigator wiring diagram from Ford and it shows you can tap into the power liftgate wire right at the switch, and the defrost wire right at the swtich, and then the headlight wire too directly (no longer requires a relay like it showed in the 02-06 Ford install file for the optional headlight illumination). I figure the folding mirrors would be similiar to the power liftgate?

side question: why for 09, they don't list the Expedition in the official 09 Ford install file? also for the F150 and other SUV's in the 09 install file, they don't list the rear defrost connection in any of the wiring diagrams? Is everything going to MS CAN Bus and you can no longer make that connection?

yes alot of the newer fords are starting to use CAN for there stuff rear defrost on yours should be at the switch though as far as the mirrors being like the lift gate there a little different the 2 switches internals are different the lift gate only shows 1 input too the liftgate module for both open and close that gray/brown may work alone im not sure but from what i can see i doesnt look that way but i dont have a truck to test it out on

well I didn't have time to mess with any relays, but I tried the gray/brown fold wire by itself and it didn't work.

as far as a relay, a saw on a message thread that someone said you could use just one relay and one AUX channel to get it to work:

Pin85 - 12vdc
Pin86 - Negative when armed
Pin30 - wire from your alarm's AUX channel
Pin87A - Fold Out output
Pin 87 - Fold In Output

Joe, do you think this could work on my truck?

the issues i see with that is

1 when the system is armed the relay will always be energized drawing roughly 150ma of current on your battery

2 your aux would only fold the mirrors out when the system is disarmed and only fold them in when the system is armed

you need the see if you can get them to work and how they work before trying to hook them to the system

good luck

just an update: we tested the wires this past weekend but did not make much progress.

The heated seat wire I identified did not do anything, so we didn't hook that up.

We found the violet/brown Fold In wire for the mirrors, hooked it up to a relay, and then it turned out it was the wire just for the driver's side mirror. What's weird is that it worked the first time we tried the AUX button, but then it wouldn't work again. We were afraid to fry the DSM or something, so we disconnected the wire/relay, and hooked the wire back together like factory, and the mirrors work fine again with the door switch. So we decided to scrap that idea.

The defrost wire tested out to be ok to use, but I decided not to hook it up since my other ideas didn't work out. It's only the side mirror defrost anyways, not a rear window, so I probably wouldn't use it anyways.

I know this is an old post, but since I work on the 2009-2010 seats I can offer some insight for getting heated seats to work.

If you only have heated seats (not heat and cool) this is a dumb module mounted under the passenger seat. Once the car is started you should be able to turn on the seats by sending simple pulses to the seat. You would have to hook relays up to specific wires in the seat wiring harness as nothing really goes to the main connector. One pulse will turn on high, next pulse low, third pulse off.

PM me for specifics if you dare to try.
