I have a 88hf and i swaped an 88si on it.
even ecu is off a 88.
and when i go to jump the connector it doesnt work.
the check engine doesnt stay on.

and i looking at a ecu wiring diagram and
found out that the B20 pin which is brown wire at the ecu
is the timing adjustment connector.

so my question is that if i could cut the wire from near the
ecu and be able to ground it to chasis in order to get the cel to stay on???
since i think there is an open within the wiring..
