I have a 1990 4bd1t that is going into a toyota t100 and i need to know whether. I need to use the whole dash harness that goes to the ignition and everything else inorder to use thr auto trans controller. Its an entirely mechanical engine with an electronic trans. As long as the trans is connected to the controller. Can i just run a power wire from the ignition to a fuse and the controller or do i need to try and graft the isuzu harness to the toyota dash harness please respond asap
