Help
I was removing an old security system from my 89 YJ and everything seemed to go well I kept getting more and more wires from inder the left side dash. I didnt think I pulled out too much but I got finished as it was getting dark tonight and thought I would crank it up to charge the battery since I had the radio running while I worked.
I turned the key and the only thing that happened was the brake light came on and went off when the key was turnes to the start position then released.
Any Ideas? I dont think I pulled out too many things but I might have blew a fuse? Is there a clutch engaged smart switch that I dont know about?
Anyone know where I can get a Wiring schematic?
Any help would be greatly appreciated.

what engine have you got? did you disconnect the battery before you started yanking wires? i may have a schematic depending on the engine. did the security system have an ignition interrupt on it. if so, you may have pulled out the jumper wire that allows the ignition to function

I got the 4.2 L 258 and no I was a Jackass and just disconnected what I thought was the big wires first (+ -).
The only way the security system would alarm before was to manually flip the switch by the battery. It had a flat key that stuck in next to the brake release then a hood lock latch but nothing worked I did'nt see a problem with removing it...

my guess would be you blew a fuse.. either inline or at the fuse box. i'll look around for a schematic for your beast

I just went out to check it again I found no fuses in the block that were blown... I looked for a main fuse saying eng. or Ign. but they were all for certain accessories. there are black square Bosch breakers??? not sure I tried it with the clutch pushed and engaged out of gear the result is the same... when the key goes to the start position the only thing that happens is the brake light comes on... Any idea's??? I wanted to trace the wires by color to see which one I might have accidentally snipped?
I am at a loss here

Seems like the security system worked well!! [img]/wwwthreads_images/icons/smile.gif[/img]

Just a thought: I've played with many security systems over the past few years and most of them have a feature built in to interrupt the starter, fuel pump or ignition. As the current needed to switch those parts of the car are often quite high, external relays are used. Most alarms I've come across can only switch about 10 amps with the built in relay. I think this is certainly where you should look. One of those wires to either the starter solenoid, ignition module, distributor feed, fuel pump etc. would have been cut and fed through the internal relay or an external one. By cutting out the alarm, you would have broken this vital feed to one of these components. Was the security device OEM or aftermarket. If it was OEM, you'd need to get hold of the wiring diagram to see how it is wired up. If it is aftermarket, there would have been a splice somewhere and that might be easier to trace. Hope this helps.

If the alarm had a starter diasble relay in the system some times that can cause it. Some systems have "Fail Safe" started disable (the vehicle can still start if there is a problemm with the alarm) and some don't have "Fail Safe". If you have an alarm that doesn't, if you remove the alarm the vehicle won't start until you remove all the alarm parts and reconnect any vehicle wires back together (ie. ignition wires or the hot wire while cranking).
Look under the steering column for a relay with two large wires going into it (same color) and two small wire probably going to the alarm. The two large wire are the start wires that would be reconnected.

1. If you don't have the wiring system memorized, you'll need a schematic.
2. Break down and buy a schematic.
3. Read the schematic.
4. If you don't understand it, ask your question her.
5. Include the schematic, scanned if possible.
6. You've interrupted a very important voltage buss. Without it the YJ's dead.
7. Look under the dash to see what wires you've cut.
8. Look at ANY loose ends and trace them.
9. Look a the wire colors, are they factory?
10. Look a the schematc, do the wrire colors corrospond?
12. Chiltons/Haynes/Mopar all have schematics avaliable.
13. Try the loacal library, sometimes they even have a manual on your Jeep.

<font color=red>If ANYONE has scanned their schematics on their YJ's, could you e-mail a copy to me? I'd love to have a set... it would help me to better diagnois problems on this forum, just like this one.</font color=red>

I do remember two larger diameter purple wires that went into a Bosch connector and it "came out" with the system I might go out to see if they can go back together and see if it will fire up thats sounding like the locical explanation I'll keep you posted.
thanks guys

Thanks for the help to everyone that replied. After further inspection I found a "little black box" velcroed up under the dash which was still part of the system... I removed that then reconnected the Orange and the GREEN wire back into wheir respective mates at the big wiring bundle and she fired right up!
Thanks Guys!
