Hey everyone. New member here. I bought a rustfree 89 Yj Laredo with factory 4.2 & Peogeot Trans. Took all that out and bought a 93 4.0 out of a Cherokee & AX 15 out of a 99 Cherokee. Everything is asll installed now no issues. I do have all the 4.0 harness laying on top of the 4.2 harness. I know the right side of the bulk head adaptor if for lights. Just need help with proper pins on ECM & bulk head diagrams for 89 YJ bulk head & 93 Cherokee bulkhead. I know the dash wires and sensors for the 4.2 will be used. Just a bit paranoid I will fry something. Thks in advance. I hoping I can get this running this week.
