ok just the word, 6cylinder.
but they had many.
early wrangler ,called the YJ jeep. true name.
be nice to know the VIN, number, xxxx on end.,
this tells the helper whats there, if still stock , is it? many are NOT.
many this old are engine swapped,
no photos by you of engine nor distributor...
nor the connector pin count on side of distributor.
lets do displacement first is it the 4.0L ?
with throttle body. injection, or a carb.?
1989 is a year of rapid changes, I had 2x 88s.
some have the french EFI , called Renix.
with 4 injectors, and a brain dead ECU. horrid.
this have there very own different spark systems.
I think the last carb ever on wrangler is 1987.
before this worse electronic carbs, yup , avoid them.
4.2L inline 6 no the 4.0L (5million made)
looks like injection did not happen on YJ until.... 1991. later
than all other jeeps, 4 years, late.
I had many of the others, my beloved, Comanche 88
500k miles long....
has spark timing, check.
has distrib. check
has sepr. coil check' has module outside, check.
im on line now at mitchells so could you.

The ignition module is mounted next to the battery on all models. It is a sealed, weatherproof unit on the 4.2L engine. 1987-90 vehicles equipped with a 2.5L engine, incorporate the coil in the control module."
