05 f350 door lock problem

Alright here's the deal.... I installed a audiovox 997 alarm/remote start in a customer's 2005 ford F350 superduty.  Everything is working great, alarm, remote start is set up to a 10 second delay to allow the plugs to warm up, and starts everytime.  Parking lights good, door trigger good.....

The only thing i'm having trouble with is the door locks.  Now i know that it is a reverse polarity system and that the locks rest at ground.  I did use two relays to get them to work, wired like this:

87 on both relays wired to 12V

87a on both relays wired to ground

85 on lock relay and 86 on unlock relay wired to 12V

86 on lock relay and 85 on unlock relay connected to alarm output wires

30 on both relays hooked to lock/unlock wires in vehicle.

I wired it like the relay wiring guide said to....(actuators / reverse polarity)

Now the locks work with the alarm 100% of the time....the problem that i am having is that when i hook them up to the wires in the vehicle, the factory switch no longer works.  I disconnect the alarm wires and the switch begins to work.  WEIRD.......The wires that I tapped into are in the door panel, and they are BLACK/ white and WHITE/ red.  It says to get them in the door boot but I hate working in that little of space, so i just ran my wires all the way in the door panel, right next to the switch, probably 6 inches from the switch.  Is that a problem, Do i need to introduce diodes, and what can i do to get the switch to work when i have the alarm wires hooked up? 

thanks for the replies...

thanks for the response.......i'll give it a shot.

Question though....you don't hook any of the relay terminals to ground? 

anybody?......I understand now that this is a standard five wire as it does have the switch, and not an actuator / reverse polarity wiring! 

One thing that might be causing a problem....This vehicle did have ignition controlled locks and the customer had that removed....or reprogrammed....or something!  They no longer work.  I have rechecked my connections and rechecked them again and again, so I know that that's not the problem.  Could the fact that the ignition controlled locks were removed be possibly causing the problem?  I'm all out of ideas and am hoping somebody can help me out. 

Thanks ckeller and installmarc for your help....I get it now why you had me wire it like that, it's just not working.....and i think it's the vehicle, because I do hear and feel the relays clicking, just not getting any movement on the locks!! 

NOTE *1 Vehicles without FACTORY KEYLESS ENTRY are a TYPE "C" Door Locking system, the PINK / YELLOW is for LOCK and the PINK/LIGHT GREEN is for UNLOCK both wires are found in EITHER KICK PANEL, you MUST use the DRIVERS DOOR SWITCH for TESTING. if vehicle is equipped with FACTORY KEYLESS ENTRY the Door Locks are a TYPE "B" System, the LOCK is a WHITE/ RED (-) and the UNLOCK is a BLACK/ WHITE (-)

You might want to double check the doorlocks wires again. On your first post, how did you get it to work with the relays setup without blowing any fuse , I don't have any idea.

alright...tried what you said and this is what i get!  Ready for this......

Unlock relay 87a hooked to ground and regular 5 wire.  It unlocks them with the alarm remote and they reverse on the switch.  (unlock on the switch locks them).....lock fails on the switch

Lock relay 87a hooked to ground and regular 5 wire.  It locks them with the alarm remote and they reverse on the switch.  (lock on the switch unlocks them)......unlock on the switch fails

Hook both 87a's to ground as well as the 5 wire and the alarm lock/unlock reverses.  Unlock on the remote locks them, and lock on the remote unlocks them, and the entire switch fails! 

This is really starting to irk me.....it shouldn't be this hard!!!

moonliter, thanks for the info and i tried looking for the pink / YELLOW and pink/lt. green wires in both kicks and there is nothing in either kick. 

And by the way, this vehicle did not come with a factory keyless system.
