Marker Lamp Relay location?

Mine is a '74 F250 Camper Special. It was restored 4-5 years ago.
My wiring diagram says there is a Marker Lamp Relay, or a plug for it.
I have a need to use this relay since I have a Camper now.
I'm betting I taped back the connector plug. I'm asking for the location of this plug. It will save me cutting into my harness and tracing the wires.
The relay itself is a three pole with a BK-W wire from the fuseable links.
A brown wire from the light switch. And a black that go to my camper plug.
I've done a search in electrical and this forum already.
Thanks for your help.

I'm sure camper special electrical plugs were at the front of the box or where the cab & box join.

Yes, I'm using the plug for the camper now. The black wire from the relay runs to the camper plug so the overhead marker/clearance lights of the camper are illuminated.
The purpose of that relay is so that one wouldn't simply use a wire from the tailights.
On my camper there are a total of 14 overhead/marker/clearance lights. With this kind of draw a relay would be needed.
Since the Camper Special has this provision, all I need to know is the location of that relay plug/connector, simply plug in the relay and I'll have my overhead/clearance lights operational as designed.

If it truly has a factory relay, It could be under the dash or under the hood.

Looking at the schematic,I would suggest it is behind the dash around the headlight switch.
The reason I suggest this is the roof marker lights harness usually runs up the driver side door pllar,therefore, picking up power from the relay near that position.

Thanks Dennis, I still may have to split my harness to trace it further.
