My 94 ford bronco has an odd wire harness that i cannot find a diagram for nor can i match any of the wire colors to any of the posted listings. the harness is small and square, for the speakers only


Your Bronco has the premium radio with separate amplifier. The harness you have connects the radio to the amplifier. The 8-pin connector is identified as follows:
RR (-) LT BLU
RR (+) PPL/WHT
RF (-) BRN
RF (+) WHT/RED
LR (-) YEL
LR (+) LT BLU/BLK
LF (-) WHT/ORG
LF (+) LT GRN

Hi. I have 2006 VW Jetta 2.0 TDI .I don't know why my car injectors socet hasn't got power electric? I changed Crankshaft sensor I changed camshaft sensor I changed injectors wiring harness.


Those sensors wouldn't affect power to the injectors.

You need a voltmeter, it's an electrical problem, so you need a digital volt/ohm meter (DVOM), or also called a multi-meter, and digital because many car circuits that are computer related operate at very low voltages or power demands, from milliamps to thousands of volts, like the ignition delivers to the spark plugs. So you buy a cheap multi-meter, then you also need a wiring diagram for your car to see how the fuel injector circuit works. but start there where you plugged in the new injector harness.

You are looking for power to the injectors, with key on. The injector harness has 8 wires; each injector has a power wire and a ground wire, so 4 of the wires in the harness should have power. At least on most American cars, the injector works by having the ecm control the ground for the injector . The power is constant. It is only when the ecm momentarily internally grounds the injector circuit that the injector fires. On your VW, the injector power wires and ground wires both go to the ecm.

What does the numeric prefix mean for wire color in a factory service manual? eg: 5 red or .8 wht


It's telling you that the red wire is number 5 wire on the wiring diagram or the number 8 wire in the harness is white.

I have a 99 accord the alternator plug was cut. Looks like they tried to splic the wires to fit a different plug or something. What wires do I run to each metal piece on the alternator?


The WHT/RED wire from the PCM connects to terminal 4 (FR); the WHT/GRN wire from the PCM connects to terminal 2 (C); The BLK (or WHT) wire from the underhood fuse/relay box connects to terminal T102 (B); the WHT/BLU wire from the gauge assembly connects to terminal 3 (L), and the BLK/YEL wire from the driver's under-dash fuse relay box connects to terminal 1 (IG)

Picture of glow plugs locations


Glow plugs are right below the injectors and have a wire harness attached to them it's a black tube looking thing with 4 offshoots going into the head right below the injectors. the harness just pulls right off and the plugs are right under. The glow plugs are threaded into the head. it is very common for the harness to fail and there is lots of options to purchase replacements there are 2 and 4 wire harnesses so make sure you get the right one if you need to replace the harness. sorry no pic. lots of info with pics at fredstdipage. (just google it!)

Your misfire can be cause by couple of things but the cheapest way that you can try to fix your car is to do a tune up by replacing:
1)all spark plugs
2)do a oil change
3)spark plug wires
3)distributor cap and rotor

note misfire can be cause by:
1.bad gas
2.spark plug and/or wire
3.distributor cap and/or rotor
4.valve adjustment
5.injector
6.off timing
7.ECM
8.bad wiring(power, ground or feed line)

Where can i find a new alternator wiring harness or (diagram to make one) for a 1985 mercury cougar that has a 5.0 engine. The local area parts/salvage dealers do not have this part.


My software won't let me link the diagram to the internet. So I will describe it to you. I'll use factory
color codes, so if you have any harness left you can
splice to it. On the regulator there's 4 terminals one
ot them is (A) from this a yell/wht wire that go's to a
fusable link then to the + battery side of the solenoid.
The (F) orng/ltblue wire go's to the field terminal on
the alternator.The S or stator wire (wht/blk) go's to
the Stator term on the alt. The I or ign. wire (ltgrn/wht)
go's to the alternator light. (or gauge) Next the B or
battery connection wire (blk/orng) from the alternator
go's to the fusable link, the same one that the yell/wht (A) wire went. Also there is a wht/blk wire
that runs from the stator term. on the alt. to the
choke heater. Hope this helps. Good luck.

Need help with 2004 Hyundai Santa Fe Audio Wiring


Sounds like you need a light tester. I would guess that at least 8 of the wires are speaker + & - the others will be Main power and earth Possibly electric ariel, Memory store and a wire for the anti theft circuit. Assuming the stereo is factory. Any Audio shop can perform a test to clarify the purpose of the wires Wouldnt worry about the blank its probably a position for a newer or different model to yours.
