glow plug controller relay wiring

[45bus]

Finishing up my engine swap. Just need to wire it and I'm ready to swap. My glow plug controller does not seem to have the same wire colors as my Chilton's diagram.

I have Pink, Black, Brown Yellow, Orange,and White

The black and yellow were connecteted to ground. White appeared to be unused.

Now I'm guessing. Orange to glow plugs, Brown to Ignition, Pink to relay with other relay side grounded. Does that seem right?

Forgot to mention. The Donor engine is from a early 80's school bus.

Would be helpful when posting a first message to first introduce yourself, and give everyone a more complete description of your vehicle. GM used a thermoelectric glow controller and separate glow replay from 1982-84, then switched to an all-in-one electronic controller in 1985. From your description, I can't tell what you've got. .....
