Glow Plug Relay Wiring

[k_williams1982]

I'm replacing the old 6.9 style relay with the 7.3 style and trying to see if anyone has a wiring diagram to do this without changing too much wiring. I have the controller, engine harness, and bullet sytle GPs too complete the swap. I'm hoping that I can somehow make this still plug into the factory harness on the passenger fender with little rewiring, or is it better to just make a new harness and mount the relay on the inner fender away from engine heat?

Ken, there's a good tech article on the conversion.

I went to Wiki first and didn't find it. I'll look again. Thanks.

Checked the Tech Articles again, and still can't find it. Maybe I'm just blind, but all I found was an article on adding a push button for manual glow plug operation.

I've got a scan from a Ford update manual, but it's too large to upload here. It's a .pdf file. If you want to send me a pm with your email, I'll send it to you.

These pics help, but if someone has a wiring diagram with wire colors from the 6.9 harness, and the 7.3 harness, that'd be great. I'm hoping to figure out a way the plug the 7.3 harness that goes to the engine into the 6.9 harness on the fender and still make everything work properly.
