My '97 E-150, it didn't come with a towing package but it did come pre-wired for a brake controller and such, even had the fuse in the box under the hood. A hitch has since been installed as well as a 6 way trailer connector. I bought a brake controller with ford plug-in wire harness for under the steering column. When I plugged it in, the right turn signal indictaor on the instrument panel came on solid, as well as the actual light; but only on the front, not the back.
Anyone know where the problem could be in the wiring to cause such a problem?
