Please help. ABS, VSS, EVAP problems

Hey guys I recently picked up a clean 00 ranger that has been 5.0 swapped. I'm a perfectionist so naturally I'd like to get the truck in perfect mechanical condition before I add any aftermarket parts.

Here's what I know. 2000 ranger 2wd, 99 explorer 5.0 2wd donor vehicle. It runs and drives great but I've got a few CEL's I'm trying to correct. The biggest ones being the ABS system and VSS codes.

Here are the codes that a present.
C1155 left front speed sensor(VSS)
C1145 right front speed sensor(VSS)
C1230 rear speed sensor(VSS)
P0500 speed sensor A- VSS is not reading

C1095 hydraulic pump motor(ABS MODULE)
P078 transmission range sensor A
P0453 EVAP sensor high input switch- probably FTP needs replaced
P1000-not worried about this one
P1729 something about 4x4??

So now for the questions. How do I connect my ABS module? I can't find a plug anywhere under the hood for it? Shown in photo below. I'm hoping if I can correct that it may also correct the VSS codes as well. I'm not sure why I have front wheels speed sensor codes. To the best of my knowledge these trucks don't have them. Keep in mind I've only had this truck for 1 day so I've not had to to diagnose or completely run through the truck yet.

Also found this tucked behind the fuse box. Looks like they removed the actual abs pump and left the electronics hooked up from the explorer. Hmmm. Has anyone successfully completed this swap while NOT getting any ABS codes??

Sounds like a computer issue for part of it. Do you know if the guy who did the swap reflashed the PCM? Might clear up some of the codes could also be that some of the parts the explorer had do not exist on the ranger. Im pretty sure the ranger only had a speed sensor on the trans tailshaft that year. Also not sure if the explorer was offered in AWD that year but it could be a replacement PCM pulled from a AWD explorer. Which would explain front speed sensor codes EVAP is most likely a leak maybe a line somewhere overlooked during swap. You might have to do some more digging around in the lines to find it. For the missing ABS pigtail might have to get a wiring diagram for both the 99 ex and 00 ranger and see if you cant splice something in.

Also is it 5 speed or auto? do you know which trans it is? So many variables when your talking a swap the parts may not have all come of the same ex and some may have been swapped on the ex prior to swap any info might help.

Is it a requirement to rehash the PCM when doing this swap? That may well be part of my issue if that's the case. The only speed sensor I've located is on the rear end center section so the front speed sensor codes confuse me.

Not a requirement but from experience when you deal with finicky new age components or if the exact transmission used in the swap is not what it came from the factory then the computer is set up for one set of parameters that the new driveline cant meet so thats why you get the codes. if you take it to ford and tell them trans and motor type as well as what features it has such as 4wd they can reflash to those parameters. Which should take care of a lot of the codes especially the speed sensor codes as well as possibly EVAP that is also a set parameter in the computer if i recall correctly the 5.0 has a return fuel line where the ranger did not could be an issue of the extra lines allow to much pressure to release. But i would start there for sure. Im still thinking that based on the codes that was an AWD ex and its freaking out because a lot has changed. They also may be able to offer more insight at Ford as that is a very common swap.

Also afterthought here but you might also check some of the wiring. If they spliced in pieces of both wiring harnesses that could also be an issue they do sell a 5.0 conversion harness for the ranger however most people do splice and it leads to issues since so many systems are integrated now as soon as you set one code it tends to snowball. These are just some off the top of my head tips. Also in that same thought if the ABS is unplugged that can trigger speed sensor issues as well so they may or may not be related as they function pretty intertwined in these trucks.

Ok new plan of attack. Anyone know who I can send my computer to that can remove the front speed sensor, ABS, and EVAP functions? I know it can be done. Just not sure who I need to contact.
