Maratrac green and orange wires

[owl9704a]

We have a Maratrac with the clamshell head. Someone lost the orange wire that had the numbers on it. The green says pin 17 ok, now does anyone know where the orange goes? I have searched and searched the net and found most people must have the A7 head. I found out where they go. Thanks in advance gentlemen. Our VFD will appreciate this.

Sorry people, been looking at too many small numbers. The green wire says 19! Not 17. Guess I need better glasses.

Green is 19 and goes to the battery.
Orange is 20 and goes to ignition.
If this is for apparatus that has a battery disconnect, they probably both can go to the same post on you disconnect.
There are jumper settings that allow you to make the TX and RX go on and off with the ignition ( orange ), or combinations of Rx by the on/off switch, and TX with the ignition wire, etc.

WOW! Thank you so very much. No we don't have battery disconnects. These are very old trucks and not very fancy. But again thank you for your response.
