2002 XLT f-150 truck camper reverse lights
I have a new truck camper and found the the 30 amp maxi fuse was blown , Its been replaced with a new one,
Been looking at the owners manual and there are relays which the reverse one was missing , its been replaced
All other lights ,Tail,Running,turn and brake lights work.....
its just the reverse lights on the truck camper i can't seems to find the reason there is no voltage when in reverse , there is revere lights on the truck and they work
Hooked up the camper to my brothers truck and reverse light work
so i know they work
Back two the owners manual there is a 30 amp maxi, i THINK 2 half relays has i think is what there called been replaced and checked
I have also 12 volts for the charging system for the camper that it works as well, its just these reverse light i cant seem to figure what ford is doing here
I bought new relays and there is a 20 mini or reg fuse that i guess is in the current path
Thanks is advance

You are going to need to specify which fuse numbers you are posting about.
The 30A could be the trailer tow adapter Maxi fuses #101 or #108.
- 101 is the battery charge relay feed, 108 is the trailer brake controller.
the trailer tow adapter reversing lamps is a 20A std fuse, #5 in the Battery Junction Box ( AKA BJB / under hood fuse panel ).
BJB Fuse #5 feeds the trailer tow reversing lamp relay, terminal #3
The normally open terminal #4 feeds the trailer tow adapter reversing lamps on the Black /w light green stripe wire.
The trailer reverse lamp relay coil is ground on terminal #2 and to the trucks reverse lamps on terminal #1. This is closes the relay's normally open contacts when the truck's reverse lamps are on.
Which 1/2 size Ford relay did you change, and how did you test it ?
- The trailer tow adapter reverse lamp relay is the half size under the horn relay and fog lamp relay. that row it is the 2nd from the right ( far right in that row is the WOT relay ).

Is there two different circuits one for the truck reverse light ?
and one for the tow 7 pin plug ?
I got it working by using ? jumping on the reverse lights wire
I ran it to the center pin on the 7 pin plug
sorry it was a 30 amp maxi it was blown,,,,, replaced the relay it was missing.
I believe this truck was taken to a muffler shop or some,one wiring it up looking at it its not factory
Thanks for the reply and help
