i have a 1989 2 door cherokee limited with 4.0/aw4/242. i was under the dash installing a remote start/remote entry unit, and while fishing wires through the firewall next to the ecm, i notice 2 wire have been removed from the ecm. going off the wiring diagram in my paperweight chilton, they appear to be for the engine speed sensor. Could anyone explain why someone would do this, and how would that affect the vehicle? i've been searching and reading for 3 days and i am getting more confused the more i try to search and read... Thank You for any help, its greatly appreciated~
