Problems w/turn light at trailer plug

[DE Jeeper]

I have seem to lost power for the passenger side turn signal on the trailer plug. I have power to all other terminals. I also pulled the connector behind the plug and still no power. I tried to fnd the splice, but it must come from the front of the truck. All fuses and relays under the hood are good. The turn signal for the truck works fine too. Does anyone have the schematic for the trailer turn wire or know if there is a hidden fuse, thermal link or possible other connection that might be causing this. BTW, it worked about a month ago and I haven't done any upgrades or changes since. See sig for truck specs.



Thanks in advance,

Aaron

I think I found my problem in the Search forum. Looks like a bad relay in the FCM. Not sure I want to handle putting an external relay into the board so I might just bypass it in the back of the truck by hooking to the truck lights. Can't see spending the money on the fcm until some other things start burning out .
