so its been a minute since i studied the schematics of the st165 harness but i need to know what is grounded to the center bolt of the intake manifold to diagnose some issues im having. I couldnt find anything to define what is grounded on any of the celica techs bgb references. so if anyone from memory can tell me youd save me alot of headache. thanks!
