Ford E-150 remote entry module 2006

hi, < newbie alert > (lol) can anyone give me a few clues as to the physical location of the dang keyless entry module in my Ford Econoline? it seemed to me the best way to install a better system is remove and replace the factory unit, since all the basic wiring is obviously available at that physical point... the install shops i visited all said they would install a new alarm and just leave the old module in place (and hot) and that just seems not such a good idea to me, so i figure i'll do it myself (i have a couple omega/excalibur units laying around here) thanks in advance Pj ps: i have done my own alarm installs including power lock actuators in the past, so i'm not totally green (just older and would have let someone else do it if they had offered a true Remove and Replace) of course things were simpler back then...

You do not need to, or want to, remove the "factory" stuff. Simply "piggyback" all the wires you need for the aftermarket unit. Someone here will provide you a link to some wire colors and locations.

FYI update as I suspected, all the wiring to do a nice Mobile Alarm install was in fact right there in the wiring harness at the location of the keyless entry module it took me a month to locate the dang thing, taking panels off the van one by one. I went to 5 professional installers, and 2 Ford dealers, who all told me there was no actual module, that it was integrated into the harness, that it could not be disabled. The installers refused to remove and replace, insisting the only way they would install was leaving the factory module active, and installing a new system near the steering column. (i offered all 5 the job, but insisted they had to do a true R&R... they all refused) bulldoodie... so i did it myself... and i was right the module is located above the fuel line reset switch on the passenger side... the module unplugs, and disabling the keyless section is obvious... slide the circuit board out of the plastic housing, snip the dipole aluminum antenna off, snip the tuning coil off the small circuit board and put it back in place, plug it back in. (the relays for the door locks are also in the module, so you need to leave that section working) removing the lower knee panel facing the passenger seat, there is plenty of room to locate a new control module. I used an Excalibur 1000 i had laying around. Schock, door Piezo, Hood, vacuum sensor, and a small radar. there is also a physical cutoff keyswitch added inline on the fuel power line, so during long periods of storage, the van is further protected from theft (can't start it if it won't pump any gas) now my van AND it's contents are protected, and a crook with a set of Ford codes can't bypass the new alarm system. I do thank the few folks who gave me a clue or 2, but i also feel it is kind of sad that Mobile Alarm installers in my area are of such narrow focused "one install fits all" mentality, and refusing to listen that it's not so much the VAN i want to protect, but it's COntents... hence i could not accept allowing the old keyless entry module to be left active.
