looking for 2004 f150 lariat bcm wiring

I have a 2004 f 150 lariat I'm trying to find either the bcm(body control module) wiring diagram or the bcm pin diagram. I have a 8 amp draw on my battery when I unplug the BCM the draw stops. I disconnected my negative battery cable and use a multimeter to find out the 8 amp draw also when I use the probes on my multimeter to touch the negative battery cable and the negative terminal all of my exterior lights come on.

Hi, Is the F150 a 10th (97-04) or 11th (04-08) generation model? Did you try removing fuses from the BCM one at a time, instead of unplugging it? This should help isolate the circuit in question. Autozone.com should have wiring diagrams, though you may have to register. Mark

it is the 04 to o8 generation not the Heritage and there is no fuses in the BCM it is one solid unit with everything connecting to it all the accessories and the security. if I pull the fuse that controls it in the fuse box it stopped the draw and if I unplug it it stops the draw. since all of the accessories are controlled by it I'm not sure if it's the problem or if its just where everything meets together so I need a wiring diagram to tell me which hot wires are supposed to be hot coming in and out of it

on autozone.com 2005 F150, power door locks. fuse 6...parking lamps, fuse 40...headlamps, fuse 107...body security module.

8 amps is a lot. It won't be the BCM, but something it controls drawing that amount of current. Like the park lights or something. I just looked at the BCM / fuse box on an 07 a few hours ago. There are a LOT of connections and wires going into it. Even with diagrams you're not going to figure anything out. Pull the fuses one at a time, and see which circuits affect the draw. I have access to wiring diagrams. Post the fuse numbers) that affect the draw, and I'll look it up for you.

going through the fuse box the only fuse that changes the draw is the fuse that is for the BSM and the power door locks it is the same fuse for both and which is controlled by the BCM. when I take the nagative cable's off the battery and take multimeter and put the positive on the cable terminal and put the negative on the battery post all of my parking lights and head lights come on.
