i have my 85 Turbo Z wired to run on 86/87 GLHS style setup done to the factory T1 harness that the car came with stock. It came this way, car was running T2 a long time. I'm wondering is there is any benefit to changing over to 88 style electronics? wondered what was involved and if it was just changing the underhood harness or if i also had to do stuff the interior harness.
