My first alarm install so bear with me. Replacing all my ancient PIRs with Texecom ones but as usual am confused by the wiring. Most of the wiring on the existing PIRs are the same, except one. How should I wire in the new ones? What goes where?

Looks like the old pirs have used a power return method , use red and black for power , then use the other two cores in eol mode, wire to the first tamper terminal on your new pir and last alarm terminal , set the pir via the jumpers to 4.7 alarm 2.2 tamper. So you will have red in 12v black in 0v White in tamper and yellow in alarm.
 
Keep it simple.
When replacing the panel and pir's it doesn't matter what the old wiring was so much, just that when you reuse the good wires that its wired correctly for the new equipment at both ends.
