'72 trailer 7 pin vs '99 truck 7 pin wiring?
From reading I understand the 7 pin connector on my '72 Argosy 22' may be an older standard configuration than the 7 pin on my '99 Chev Silverado with factory tow package.
My confusion is that everything seems to work except the electric brakes. All the running lights and the turn signals are fine. However the brake controller tells me there is no trailer connection. As the other lights work, the ground is good.
The truck has a blue wire for the electric brakes, the trailer may have a yellow wire for the brakes from what little I've been able to determing. The pins for these wires don't match up when plugging the trailer male into the truck female connection. As the trailer has the original pigtail I'm considering replacement, or rewiring the current trailer 7 pin.
I'm under the impression that these difficulties are not uncommon, but I'm a new owner and as a result I could use some more informed and experienced opinion regarding a solution.
