Using stock ECU with a harness modified by MR220V.
Started the teardown last night and made some good progress. Got most of the wiring undone, airbox, battery, driveshafts and exhaust removed. Plan on draining the fluids on Thursday and dropping out the 4AGE then making time to clean out all of the grim in the engine bay. Unfortunately I found some rust forming in the rear quarter seams in the trunk :(
