Default Orange and Blue wires on 48 volt upgrade w/reversing contactor

I have read several other threads regarding this.
I am still confused though.
I am wiring in a SPM 48500EZ (5-pin model) with reversing contactor setup.
I have read everywhere where it states to "Butt Connect" the blue and red wires together. But, I don't seem to have a red one leftover. I do have an orange one though. Did I "Mis-connect" one of the reds?
I have a green, orange, and black lead coming from a black corrugated wire loom.
And, I have a blue and a green lead coming from another "Grey jacketed" set.
I have the following leads connected:

Green connected male (black loom) spade to green (Grey jacketed) female spade. (correct I assume)
The "Black" lead goes to one side of the "backup buzzer". But where does the other side connect to?

I have the "Blue" lead with a female spade not connected to anything.
I have the "Orange" lead with a female spade not connected to anything.
The "other side" of the backup buzzer needs to be connected to somewhere.

I have
Thanks for any help. It is greatly appreciated.

BTW: This is a 2000 TXT Shuttle 2+2 with the factory Horn/lights/signals/brake lights.
I am utilizing the 5 pin connector on the new SPM48500EZ I will have further questions later regarding wiring the 2-position keyswitch for the lights and the voltage converter.

I think you might be referring to my instructions? The original Rotary F&R has a red and a blue wire going to the primary micro-switch on the driver side of the F&R. This switch simply turned power on and off for the key switch. When removing the Rotary F&R and its micro-switches, simply but splice these two wires together to provide power to the key switch.

The red wire that would go to the blue wire should be in the loom coming from the charger port with the heavier White and Black wires.. Unless someone had bypassed it straight to the battery pack.

Scotty,
I am looking at my original pics of the rotary F&R right now.
The orange wire was originally connected to the same microswitch terminal, as the red lead that goes to the buzzer (passenger side top micro switch).
The blue wire was attached to the other micro switch located on the drivers side of the F&R. The 2 micro switchs were wired in series with a short red wire between them.
I will try to figure out how to load a pic.

Would the Orange wire be for the 12 volt trigger from the switch, for the lighting circuit?

The red wire below my fingertip goes from the left to the right microswitch.

Orange wire is the reverse half speed. and it was on the passenger side ms
The blue and red were on the driver side ms - they splice together.

Do you have my diagram or is this from somebody else?

Orange wire was originally sending pack voltage to the controller to tell it that it was in reverse. It also had a connection for power for the reverse buzzer.

Edit... Too many people helping so I will bow out.. Good luck..

Scotty,
I am using your diagram. I did not see any reference to the Orange wire though. That makes sense now. (I probably overlooked it)
Question now, as I am using the 5-pin plug on the SPM, should/can I connect the Orange wire to limit the reverse speed? Or, should it be terminated (dead)?

Thanks much.

Thanks for your help. You and Scotty gave me the answer at the same time.
I didn't notice an Orange wire reference on my diagrams.
