  • What year Bronco II do you have?
  • Is it stock or modified?
  • what trans do you have?
  • what aftermarket items are installed?

the only wire that should be running to the hood should be for the hood switch...that should be light green and yellow wire

if that gets shorted to ground the most likely result will be a blown fuse #8 15A

then you probably won't get the glove box light, map lights and/or door ajar switches

If you could post a few pictures of what you see that would be GREAT
schematic is too bib to post here but this is what I'm looking at.....

    Hi Reisdos~realizing that I have posted in a different location than before, so to get you updated my 1988 Bronco 2, 5-speed ,2.9l,4x4 shift on the fly, got attacked by a nesting squirrel over the weekend. I posted my problem earlier today. Did quite a bit of damage to the wiring under the hood. Chewed OBD completely off, got part of eec-iv wires, some wires on on the driver side of engine, built nest with alot of insulation from underneath hood. So I've repaired wires but Ive got a short somewhere. The moment you turn ignition the whole system shorts out so I unhook the battery to reset computer. .It reads "95" for a trouble code. Right now engine needs de-greasing before I can make sure I have all the wires repaired. The wire cord I mentioned earlier is a silver woven cord maybe 5mm wide x 6in. long and is attached to the back corner of the hood , above OBD tester. The end has been chewed so I don't know what other end looked like. Thought it could be a ground wire but don't know for sure. The real kicker to the problem is that Ive just replaced the transfer case motor because the shift-on-the-fly went out and it was\ is still stuck in 4-LO . I havent got that problem fixed yet and along comes that damn squirrel !! It went NUTS then BOLTS. There has to be a little humor within this mess. Thanks for taking the time to help. I will get engine de-greased tomorrow and get back with you~Thanks BUMURRRRRRR

94 s10 fuel pump relay clicking no start

The clicking noise at the relay indicates that the relay is bad, or that the wires to the relay and/or connector is bad.

A relay is an electronically activated switch. Inside is a coil. When 12v+ is applied to one end of the coil, and a ground is applied to the other end, the coil gets charged, creating a magnetic field. This magnetic field literally moves a metal lever from position A to position B. One end of the lever is attached to constant battery power. When coil not energized, the lever rests in postion A (which in the case of the fuel pump relay is feeding the battery power to an unused terminal). When the coil is activated, the lever moves to position B (which in this case is a terminal connected to your fuel pump wire). Thus, when the relay is activated, 12v+ is being directed from the battery to the fuel pump.

This fast clicking indicates that the relay coil is not getting a constant voltage or ground supplied to it, thus the lever is moving back and forth between position A and position B, either there is a wiring issue, a connector issue, or an internal issue with the relay.
The relay has 4 wires, black, grey, orange, green with white stripe.
black = ground
orange = battery = 12v+ always
grey = wire out to fuel pump (on some cars this wire is tan with white stripe)
green/white = signal wire from ECM

When key is turned ON, the ECM sends 12v+ out on the green/white wire to the relay for about 2 seconds - this activates the relay coil for 2 seconds, thus running the pump for 2 seconds (priming). When the vehicle is started, the ECM sees a constant ignition signal from the ignition module, and sends a constant 12v+ out on the green/white wire, thus activating the relay coil constantly, and thus running the pump constantly.
When car shut off, no more constant ignition signal, thus ECM stops sending the 12v+ out on the green/white wire.
So, you can kind of test your connector ...
1) remove connector from relay
2) jumper a wire from the slot for the orange wire to the slot for the grey wire - fuel pump should run - wiggle wires to verify at connector
3) probe black wire slot with ohm meter - make sure black wire has constant ground - wiggle wires at connector
test relay ...
1) remove relay from connector
2) rig a ground wire to the tab that had the black wire when in connector
3) apply 12v+ to the tab that had the green/white wire - relay should click once and do this every time you apply the 12v+

That should help you track it down to either a connector problem, a wiring problem, or a relay problem.

I have a 1985 4.1 cad coup deville I. replaced the motor,now I'm down to the starter wiring,6 wires i know the battery goes on the large post and the purple wire goes on the small post,that leaves 4...

OK, There should not be a "Tan" wire there. It is probably the "Red" or "Orange" wire that has faded real bad and just looks tan. It goes on the same post as the large black battery cable. It should be a 10 gauge wire. The other end of that wire goes to the "BAT" terminal on the alternator. (in case you want to check and make sure) The smaller black wires should be ground wires, They will attach to the transmission housing. Usually, there is a special bolt with a stud made on the end of it and a nut that secures the wires. As you said, the purple wire goes to the small post on the starter solenoid.

New Blower Motor, Resistor, Relay, Switch, all is new. Still nothing works. Any advice would be greatly appreciated. Please Help me out. HINK1974

There are two fuses a 40 amp in the power distribution center and a 10 amp in the fuse block. Are they good?

This is a ground side controlled system meaning the switch provides ground instead of power. With everthing plugged in there should be power on all the wires coming out of the blower motor resistor ( brown w/ tan, Light Blue, Light green w/ black, and tan wires). If you ground any of those wires the blower motor should run. If it does check the dark green wire at the HVAC control head. Backprobe that wire with it plugged in if there is power than either the control head is bad ( the mode switch has the final say in the path to ground for the blower motor. When the mode switch is in the off position the blower will not work. When it is in any other position (vent/floor/defrost) it allows the path to ground for the blower motor to be complete.

The last thing to check is to make sure the black wire coming out of the control head has a good ground. That is the final path to ground for the blower motor.

My o3 navigators adjustable brakes will only move about 1/2 inch either direction. It's fine if they don't work but is there any way to move them to the farthest position manually?

With both tail light lenses removed locate the black with yellow wires and the dark green with brown wires coming out of the brake/tail/turn signal sockets.

The black with yellow wire will be the running lights or tail lights and the brown wire from the trailer harness will attach to it.

The green wire on the trailer harness will be the right turn signal and will be attached to the passenger side tail light harness dark green with brown wire.

The yellow wire on the trailer harness will be the left turn signal and will be attatched to the dark green with brown wire on the drivers side tail light harness.

The white wire on the trailer harness is the ground wire and will need to be attached to a good ground. Is it pretty easy to crimp an eyelet onto the end of the wire and use a self tapping screw to attach it to the body behind one of the tail light lenses.

Here is a trailer light/wiring article I have done in the past. It has a couple of good tips you may find useful.

I have a 2004 F150 supercrew 4x4 and it will not shift into park and when I start it I have to put it into neutral any help Thanks

Sounds like the shift interlock circuit has an issue.

This can be 1 of 3 places

1. The fuse for the Shift Interlock circuit. This is fuse #16

2. The shift interlock switch. This is part of the BPP ( Brake Pedal Position ) Switch that also controls the brake lamps. There are 2 switches in the BPP switch, 1 for the shift interlock, the other the brakes. The circuit in the BPP switch for the shift interlock is the Tan w/ Red stripe wire ( from fuse # 16 ) to Pink w/ Light Green stripe ( to the shift interlock solenoid ).
Test both side of this circuit with a meter ( to ground ) you should have power on the Tan w/ Red stripe wire any time the key is in the Start or Run position.
The Pink w/ Light Green stripe wire should have power any time the brake pedal is pressed down.
If you do not have power at the Pink w/ Light Green stripe wire, you need a new BPP switch.
If you have power with the brake pedal pressed on this wire, you need a new Shift Interlock Solenoid.
