I have a 92 sc300 with a 1jzgte 5-speed soarer swap. The car ran fine but the battery died. So my sister helped me jump it but her dumbass put the jumper cables on backwards on her car. I replaced and checked all the fuses and relays and the ecu is fine. I got a 1jz pinout and checked all the wires connecting to the ecu to make sure the ecu was getting power. A couple where not so the ecu wasnt gettin power. I wanna make sure theres no possible way its something else before i pull the harness. And I have no check engine light what so over.

Let me know what you guys think...Thanks
