Switching to 2003 pcm

Used only on the 03/04 Marauder but can be used on any 03/04 ecu with code changes. Uses newer style SCP array so will not control cluster correctly on 2004 and older fords that use the older style SCP array such as mustangs.

Vehicle Information: 1997 Mountaineer 5.0 that originally had a wasted spark ignition system. I'm converting to coil-near-plug. I will use a 4.6 Luxury Sedan PCM & modified powertrain harness. It will be reprogrammed to operate the Windsor 5.0.

After much stubbornness on my part, I will be switching to a 2003 pcm.
I suppose that I can use either of these 2003 units, but I thought that I would ask just to be sure.

all any of us will do is just plug in the number in the hardware search on the homepage under supported ecus

Well, I have done that, and one says yes, the other one blank. You previously said that the data was compiled in 2014 and said that it got tedious to check out every possibility.
MPC-185 checks out, however MPC-189 does not but it probably does seeing that you have all these listed consecutively.
MPC-175 MPC-176 MPC-177 MPC-185 MPC-186 MPC-187 MPC-188 * MPC-195 MPC-196 MPC-198.
Essentially, I'm personally asking about MPC-189. It's a 2003 Crown Vic pcm. Thanks.

that means that ecu hasn't been tested
