LITTLE BALL, LONG GREEN, TEE YOUR WHITE BALL.
Light Blue, Light Green, , Tan, Yellow, White, then Black are the injector wire color codes .
If you know the pair in the middle is right, you only need to check one on each end.

My '89 has always had issues running smooth. One day I have to replace all 6 injectors, the next my exhaust manifold cracks, followed by the injector wires needing to be replaced. Everything adds up to the damn thing not running tip top. These cars are for people who LOVE jeeps and LOVE working on them every weekend, because that is what you will be doing.

I often wonder what the XJs were like new (first 5 years) as far as reliability. I would think they must have been great.
