Did you have the transmission in neutral & the ac off when you ran the koeo test??If yes,you need to troubleshoot code 67 first.Its related to the NSS circuit(which is used for idle control strategy)& having this code logged in a manual transmission equipped Mustang will cause stalling,idle surge & rolling idle.The EEC uses the NSS circuit for idle control,so it has to be able to id a "in neutral condition" anytime the clutch pedal is depressed & anytime the shifter is placed in neutral,otherwise the engine will stall.If code 67 is logged as a failure,it wont let the koer test begin,due to safety reasons.So in otherwords,you'll have to eliminate the cause for code 67 before you'll be able to run the koer test.The following link will help you troubleshoot code 67.
NSS/Clutch Pedal Switch Code 67 Troubleshooting
The fact that you had to use the alternate connection method to run the koeo test is usually a sign that there's an issue with the signal return circuit,either between the vip connecter & the eec 60 pin connecter or inside the eec itself.When you connect the jumper wire to the top right terminal on the VIP connecter or you connect the scanner to the VIP connecter, you're using the signal return line.If the methods above don't trigger the tests to begin,but connecting the jumper wire to the (-) battery post allows the test to begin,that tells you the signal return is open.
Another thing that leads me to believe the signal return line is open relates to the multiple codes you've got.
BP (code 22)
Every single one of these sensors uses/shares the same signal return line.Anytime you've got all of these codes present,on top of,not being able to use a scanner or jumper wire at the VIP connecter tells me 100% that you've got a blown/melted signal return trace on the EEC circuit board.I'll post pictures below & a link so you can see what this condition looks like & how you can repair it yourself with a soldering gun and tiny gauge wire.After you remove your EEC from the passenger kick panel and take the back cover off of it,make sure you inspect the 3 blue capacitors too.One last thing I recommend doing is the salt & pepper shakers maintenance.All of the sensors( you've got codes stored for)listed above has 1 or 2 of their wires passing through the salt & pepper shakers,so you could also have loose or corroded pinouts on these connecters causing your codes.The following link will help.
