That would be me. I'm not an autosparky but a mechanic, I've just closed my workshop due to family and health reasons so not full time any more so there's going to be a wait of probably 6-8 weeks before I can even fart in your general direction. While I have all of the necessary schematics for the UZs I will require the same for your Cherokee. There is your homework, get in contact when you have it
