'99 hard top wiring harness intalled; craziness ensues

First post. Help!

Got a used hard top for my '99 last year. Finally got the wiring harness for it recently. Put it in over the weekend. It doesn't work!

Well, it's a little more complicated. It mostly doesn't work. However, weird stuff has happened.

First off -- I am an audio engineer by trade, and a fairly anal person, so I'm pretty certain I did a good job with the details of what goes where, soldering, shrink tubing, etc. Though, the instructions were a little funky in places. Now, the weird stuff...

1) When I hooked the battery back up following the install, the CD player started playing. With no key in the ignition!

2) While the CD player was playing, I pushed the rear wiper button and the speakers turned off. NOTE: the CD player kept playing; just no sound coming from the speakers.

3) Thinking it was a freak coincidence that the speakers went out right as I pushed the wiper switch, I pulled the CD player/radio out of the dash to start trouble-shooting the wiring to the speakers. I disconnected the CD player/radio's multi-pin connector from the back of the unit, checked the fuse that was back there (it was good), then plugged it back in. The CD started playing through the speakers again. AND -- the rear wiper started going!

(At some point I had put the key into the ignition to power the CD player. Despite the fact that it worked with no key at first. Not sure when I put the key in. Could've been during 3), above, or during 4), below.)

4) I was able to start/stop the wiper a couple times via the switch. But then at some point, the speakers stopped working again and the rear wiper stopped moving. I was not able to recreate the conditions to get either the speakers or the rear wiper working again. Never got to check the rear defrost, but the little light in the switch has not ever come on. Remember -- the CD Player/radio never loses power (with the key on), even when the speakers are inexplicably not able to make sound.

There's one spot in the instructions where they talked about an orange/white wire and what I had was an orange wire. Not sure if that's relevant. There's another spot in the instructions where an addendum says that one of the illustrations is not clear, but then doesn't really clarify very well, though I think I did the only thing that made sense (it involved sticking two harness wires with lugs into the back of an existing connector). Again, not sure if this is relevant. I also have a leftover part from the kit which looks like this:



It has a '40' and a smaller '32V' molded into the clear plastic window. Fancy fuse? Not addressed in the instructions (not in the parts list nor in the step-by-step). Relevant? I don't know.

I've checked the fuses; they all are good. Also, I do hear the relay clicking on and off when pushing the rear defrost button.

Weird, right?

I am not at all crazy about the idea of chasing this down on my own. We all know how much of a PITA it is working up under the dashboard (upside-down with no room to even get your hands into play). Next stop is a Jeep shop or dealer, unless...

Any insights would be most welcome. Thank you in advance for your help.

Without knowing what's wired to what, I think it's going to be hard to have any answers for you. I can tell you that the solid orange wire behind your dash is the dimmer line that feeds your instrument cluster lights and radio lights when the headlights are on. That same line should feed the lights that are housed in the rear wiper switch and the rear window defogger switch

I have a 2000 with a hard top. I have a ton of those fuses you showed. Don't even know what the abbreviations are but I'll attach pics that might at least show where the fuse goes. Hey at least your Jeep does party tricks now

To begin with, that photo is of the 40a fuse that the instructions step 21 says to put in position 15 in the PDC. It says 30a but the supplement for ’99 corrects that to 40a. That is for the rear defroster. With that fuse installed the indicator should light & the glass should get warm when you turn on the switch. There is a timer in the cluster that will turn it off after 10 min. if you don’t turn it off sooner. Those are the 2 wires in step 43 that are noted at the end of the supplement.

As to the other problems, it is hard to tell what happened. It sounds like the CD player is not factory original so I’m not sure how it is wired but if it uses the original connector it is powered from fuse 15 behind the glove box. If so then it seems that that circuit is getting back fed from a battery (B+) source. When the CD player is running with the key off see if the front wipers & the turn signals work too.

The orange/white wire from the kit connects to the orange wire to illuminate the 2 new switches when the lights are on. Re read the 1st 3 paragraphs of the supplement on how to do that. Because of the change for ’99 you can’t plug in the connectors & have to splice that wire into the orange one on the heater/ac switch.

Thanks for the comic relief.

I get it, now. Actually, my Power Distribution Center (or whatever it's called) doesn't use that type of fuse, but rather the large version of the 'normal' type. The kit included a 40 amp fuse of that other type, which I placed in the appropriate position in the left-hand section of the PDC. I guess this green 'boxy' one is for vehicles using this other type of fuse.

As mentioned in my last post, my vehicle uses the large version of the normal flat-type fuse, a 40 amp version of which was in the kit and which I used according to the instructions. I guess this was an extra for vehicles using this type of fuse.

Correct, it's an after-market (Pioneer) radio/CD player. Unfortunately, I can't get it to turn on in the key-off position again.

I followed the supplement instructions as best I could. It's a little disconcerting because, while the supplement instructions talk about an orange/white wire leading to the two connectors on the kit harness (which were to be cut-off), there wasn't one -- only an orange wire, which I had to assume was the one they were referring to. Also, the back of the HVAC control panel did not look like the one in the instructions, so I had to guess which connector was the one they wanted me to center-splice to. There was only one 5-way connector (as described in the supplement instructions) on the HVAC panel, so even though it was not located where it was supposed to be, I assumed that's the one they wanted me to go with. There was also only one orange wire on the whole HVAC panel, I believe, and it was in cavity 4 of a 5-way connector like they said, so...

Yes, I think they switched to the square type in 2000. I was thinking in '99, I guess. Any progress on the other issues?

OK, thanks. I guess I was hoping others had run into something like my experience, but maybe not. I'm sure there are others who have the same Jeep and the same harness/instructions; but maybe the previous owner, who put in the radio/CD, screwed it all up somehow.

Nah. I was hoping someone would say "Oh, yeah. That happened to me, too. Here's the deal..." No such luck.

I think I'm resigned to taking it into a mechanic and paying him to figure out what the hell is going on. I just have too much on my plate.

You posted when I was typing. Yes, they changed the HVAC panel from the slider style to the 3 knob type in '99 & the instructions show the early version. That is one of the reasons for the supplement. Yes, only one orange wire for the switch illumination.

Thanks. Gotta wonder why the instructions say orange/white for that overlay harness wire when the actual wire was orange. Oh, well.

So long as the connector of interest moved from the right side of the HVAC plate to the top center (as seen from the seats when the panel is installed) when they went from sliders to rotary knobs, I can't imagine what I did wrong.

It's starting to feel more and more like the radio install was screwy. I guess.
