Default wiring

Hi folks . I am stumped : There are 4 wires on the Jeep pigtail ( black- white-red-green) while there are only 2 on the trailer pigtail and harness . I figure black is brake and white is park . The ground is normaly green in general electricity . What is red for ?

Found the answer on G503 : Green = tail light , Red = Stop light , Black is ground . White = Black out stop . There are just 2 wires on the trailer ... What happens with the White wire ?

The original wartime trailer cables only had three wires in a green cloth covered loom. In the manual for the trailer is a wiring diagram.

Thanks Jordan found it . I am going to improve my road survival chances by adding a second stop light on the right side . Originality is nice , survival to see another day is better .

Default Found it

Hi there folks . Found it . Black is stop and white is tail light . The stop light is always on. The tail lights are on when the differential ( round white ball ) light is off and conversely the tail lights are off when the white diff light is on at the switch . So you really only need two wires after all ! Red from the Jeep is ground to the frame of the trailer . The WW2 US Jeep as used by Canada also has 4 wires in the trailer socket : Black , White , Green and Red . The White from the US pigtail was for BO( Black- out ) Stop . It is not needed on the Canadian trailer so i will just cancel it . The 3 others are Stop- Tail- Ground . Simple isn’t it ?

Default light harness

Hi . The trailer light harness is done and tested . All lights work . I have added like i said previously a second brake light for safety reasons . I will install the harness after work in the next few days .
