Sorry about making you dizzy really not my intention. The wire schematic and pinout are wonderful thank you. So today I have checked the glow plug controler output or pin 101 on the pcm pinout. The wire checked out ok both by ohms and by no negative or positive power. But when computer is hooked up and the wire hooked up to GPR I run a start cycle on the motor so it activates the glow plugs then the wire will have 6 to 7 volts showing. Is this normal (not acording to my research)?
