I have a feeling right now that you are missing the board used to calibrate the guns.
It sits on top of the coin box. Have one?

Also do you have a manual? PM me and I can send you a 30+ page .pdf if needed.
 
I wouldnt worry about those plugs, I do not have them hooked up either.

They appear to be for this:

There was an option for the operator to return the quarter or token after the player reached a set score. I have a feeling that "feature" went over like a lead ballon, I doubt you will find many of those in the wild. My cab has a hole for that mech, but that is it.
 
Couple more pics to show some of the cool features of this cab. I had a hard time finding any pics of a Great Guns before I found one.

Lower door unlocks and pulls away

Gun panel is hinged and has its own prop to hold it up. The Monitor is a std 19" mounted low, but fires up through a prism to make the screen appear bigger than it really is. You can see the prism in this picture. Of course when playing, you are viewing the image off a 45 degree angled mirror.

You can see how much bigger the image looks compared to Cheyenne in this pic. Both have 19" monitors, both fire at a angled mirror.

thank you everyone, that puts the missing wire mystery to a close, my cab has yellow on side and orange in front, now the next question who repair's the pcb?? i re capted the power supply but i had no luck, and where to replace the big cap on lower board?
 
i cant wait to play, the power supply just sucks i wish there was a way to install a switcher +14 -14 +57v are going to be tough to install a switcher

Mine has a switcher hacked into it. Dated 1993 :)

Original power board is gone. There is at least one "custom" circuit board that appears to have been made for the switcher conversion.

You can see the custom board here (blue cap facing up) as well as some of the wiring hacks.
