what ecu do i have?
he has a obd0 car converted to obd1 .... 4 wire is on obd1 and obd2
obdo has the 1 wire o2 and also the obd1 (cx)
unbolt the cover and take a pic of the plugs going into the ecu. 
from there i can tell you what those wires goto.
as for the cel's going off when you turn you car off have your checked your fuses under hood and dash?
