s50 wiring issue

[325islovE]

i got a cranks no start car but some digging around in the adaptor i got, it seems i have a short in c101 pin 20 and 7 and they short to x20 pin 21. My question is what does pin 20 go to on c101(brown wire body side/green wire plug side)? dug around the etm for hours and cant seem to find it.

C101 pin 7 should be hooked up to x20 pin 21 right?(ecu power)

Pin 7 is the ignition switch. What car o you have. Pin 20 is not used

on late cars it goes to the ABS system to provide power

on earlier cars it does nothing (including your 88 ).

disconnect it
