so my ‘89 wrangler might work? sweet. put the top down and cruise in the traffic free streets of NYC. shotgun in hand, of course.
An 89 wrangler probably is fuel injected. Generally cars that are pre-1985 are before fuel-injection, and generally those 1985 or newer are fuel injected. A way to remember this is that around 1985-86 was when the first cars came out that you could attach a code reader to (ODB). Before that there were no computers to attach anything to (unless it was proprietary to a certain high end vehicle).
