I just installed the Painless kit for mine and although it was expensive, it did install pretty easily. A word of advice, get a starter relay when you order the kit. Painless has a part number for one but I couldn't find it on their site anywhere so it may be discontinued. I ordered this one: 1988 JEEP CHEROKEE PIONEER Starter Relay
) because I think it's the right part but it's not here yet so I don't know for sure. My relay was bad and I had a heck of time finding any info on getting a new one.
As far as getting you up and running, I'm afraid I'm not much help with your current situation.
Good luck to you!
