Well I finally signed up so I can post, I have been reading a lot here and have learned a ton, thank you to everyone who has contributed. I am I’m the process of getting the wiring done with an ALH engine in an 89 Toyota. The many good posts here, my Bentley manual, and the Haynes manual all day ndicate there should be a purple/white wire from pin 42 on the ecu to the glow plug relay. There is not a wire in pin 42 and no purple/white on the relay. It is an 03 Jetta that my brother drove for a few years before it got totaled, I know the glow plugs were working and I didn’t take any wires out of the ecu plug. I’m kind of at a loss. Any help would be greatly appreciated. Thank you
