So in spare time between other projects I've been trying to figure out why the singals and brake lights went out on my 95. First it was intermittent, then just a buzz, then just nothing at all. So I got out my trusty FSM, and proceeded to trouble-shoot. Easy, no? Guess again. I go through every switch, every bit, everything tests OK. I finally determine that the ping/black wire to the relay panel and brake switch is not live. Wiring diagram shows this as a straight shot, same color, etc. to the power distribution center, where there's a big fuse labeled "hazard flashers." Is there a pink and black wire there? NO. It's a black and white wire. Is there a corresponding wire at the bulkhead connector? No. Is there a pink and black wire there? Yes, but it's not connected, apparently, at either end. Apparently, these wires just vanish into the harness and never come out the other side. I can make it all work by simply jumpering a hot line to the relay panel, which is what I guess I'll do, but I just wanted to rant about the obscure, multi-page, mislabeled and unfathomable wiring diagrams in Jeep FSM's. I know it can be done better, because I have an FSM for my old Chevy truck, with a huge, large-format wiring book that is just beautifully done. VW used to do theirs in color. It is possible. Just not for a Jeep.
At this point, I've invested enough time trying to do it right that I am done trying. A jumper it is.
