Question about Cars & Trucks

1 Answer

Wiring problems Bought used and someone has spliced two different colors of wires together. There was no radio in it when I got it from a police auction, the wires were just sitting in there, where the radio goes. How do I tell which wires go to what? I've never installed a radio into a car before and the fact that i don't know what color means what isn't helping. Please help!

Best bet is to hire a professional, it gets frustrating. you can use a multimeter and a toner to find each speaker, multimeter to find ignition and power etc. i can promise you that without help it is nearly impossible to learn how to wire an "aftermarket" stereo into a vehicle it does not belong.

On a 2000 Mercury Grand Marquis there is no voltage at the radio connection. Both fuses are in tact and tried a new radio, still no function. Any input what else might be the problem?

Hi mr Pettit, ,,,!!!!!!!!VERY FIRST THING CHECK ALL FUSES IN FUSE PANEL !!!!!!!!is this an aftermarket radio or is it OEM.?(factory)
reason I inquire is if it is an aftermarket then when it's installed
the wiring HARNESS. Is generally cut off and the power supply as well as out put speaker wiring and ground (if provided,many radios are grounded by the direct mounting of the body of radio bolted to the framework of its location or CHASSIS GROUND and the antennae connection also is ground ) wiring to intercept the leads on the radio .. If someone has cut off the harness then either they used the original BAT + conductor or they have added another separate wire . Obviously the circuit must be open on Bat+ conductor or there is NO GROUND . . YOU stated there is no voltage at the connection so the BAT + circuit is open . Check to see with test light to and locate the hot wire that may be added and may be the reason for adding . This wire will most likely be loosely taped intermittently outside of bundled wire going to fuse panel on drivers Side and may be improperly installed into fuse panel or has been pulled away from connection at fuse panel . Is very likely,
Or where the added wire has intercepted another hot wire and improperly terminated or spliced or has pulled away here . Now if this wire is spliced INTO ANOTHER HOT WIRE CHECK ALL FUSES AND NOT JUST THE RADIO FUSE . After you establish the bat+ and connected to stereo there has to be a GROUNDING SIDE . Check to see . If you are perhaps , and am only speculating ,,testing it by simply temporarily placing stereo on seat or floorboard prior to bolting it in ,and connecting only the BAT+ wire you will also need to establish a ground and is easily done by connecting antenna wire if long ,enough or a short length of wire used as a jumper will do. Simply strip both ends of jumper ,power on radio and touch one end to any metal KNOWN part of car or CHASSIS , OR where it bolts up and touch the other end anywhere on the case or body of radio. Not to worry if you are touching any part of the stripped ends or other metal parts , you won't get a shock but you will see a few sparks and this is a good thing, and good in both aspects meaning a) your not getting lit up ,and b) there is current draw and the spark is an indicator you got it !
Huhuhaha , your fine . Look on radio and you should see lights ,LEDs or other sources to indicate power is on .. This is the best way or idea I have and know this from many times I've forgotten about the ground , I don't know why I do that though . Hahaha Also at this point
you could temporarily test your speaker wires and is a good time to designate their location with output of speaker wires from radio
use different color tape to identify ( red and black ) + And - of speaker wire and a different color tape to indicate what channel or location of speakers and write it down ., then it's simply a matter of matching color to color in that little tiny pain in the neck space the stereo fits into . . Let us know of your outcome , I'm actually real real curious personally . If this doesn't fit up your problem let me know in the comment box and we will figure it out together , it's a simple fix I do think so ..........

How do I remove alarm brain box from wiring on a

"I bypassed the immobilizer circuit only on my alarm module (which is really tedious). Bypassing the whole
module is possible (and little easier), but you will lose the use of the remotes and the ability to arm the alarm.
The alarm module in my '97 900 SETC is located under the carpet, below the driver's power seat switches (a
pain to get at).
If you want to bypass the module completely:
1. Disconnect the battery (make sure you know the radio code-if needed)
2. Unplug the connector from alarm module and remove module from car
3. Install a wire jumper between pin 8 and pin 20 in the connector
4. Install a wire jumper between pin 9 and pin 21 in the connector
5. Install a wire jumper between pin 10 and pin 22 in the connector
6. Wrap securely with electrical tape
If you want to bypass the immobilizer circuit only:
1. Disconnect the battery (make sure you know the radio code-if needed)
2. Unplug the connector from the alarm module
3. Cut the following wires from the back of the connector and splice together as follows (Don't cut the wires too
close to the connector, because someday down the road you may want install a new module, so you'll have to
reverse this process):
4. Cut the wires to pin 8 and pin 20 and splice together w/ wire nut
5. Cut the wires to pin 9 and pin 21 and splice together w/ wire nut
6. Cut the wires to pin 10 and pin 22 and splice together w/ wire nut
7. Secure all with electrical tape
8. Reconnect the connector to the module
Not knowing the details of your problem, please be aware that this may, or may not, solve it. Good luck and let
me know how you make out."

Rodeo fuel pump rewire

Usually on these it is the fuel pump sending unit. But here is how the wires connect. Here is what you need to do about the different wire colors. First disconnect your negative battery. Drop the fuel tank and replace pump. Remember to have a splice kit in hand. Ok now here is how you connect the different colored wires. Black goes with black. Gray goes with black and orange wire. Purple goes wit blue and yellow. And the last wires goes together. I hope this helps.

High consumption of fuel,smoking alot and sometimes hardstart.After consulting with some experts and doing computer diagnosis it showed opening and closing idling coil and airflow sensor were all faulty.I...

Have the wires to the airflow sensor been cut and spliced back together? Because it sounds like someone put an airflow sensor from another vehicle on the car and rewired the harness so it would work. If that's the case, find where the wires have been cut and spliced and put them back the way they were The wires should be different colors, match the colors.

Radio/cd player went dead. Tried replacing fuses

Do NOT Cut and Splice. Your local parts store sells an aftermarket radio plug in which connects to your factory harness and then you can splice in your radio into the new connectors ends that are labeled for what they go to.

Hello tnvolsfan32,

Use the FREE drawing available on the
BBB Industries site to trace out your wiring...
BBB Industries Premium Alternators Starters Power Steering Products

First put the wires together that
back to the drawing and find out what
disconnected or swallowed.

Generally wires DON'T CHANGE COLORS
in a wiring harness run... So you definitely
need to look for a LOGICAL EXPLANATION.

Registration is required... these are real
wiring documents...

Each time you return from a WIRING page
make sure you have not
defaulted back into TSBs...
(technical service bulletins)... While usually
quite useful... they don't begin to address any
WIRE-EATING-DOG problems...

If you get confused comment me back...
I can recommend some great tools to help
SPLICE everything back together

Tone Tracer being PRIMARY
Extech TG20 Wire Tracer and Tone Generator Amazon com

Helpful hint: wire must be ISOLATED to trace correctly
(pulled fuse or chewed through works).

Hope this helps

Just wondering if you can help me with a electrial wiring problem? the wires have melted together and dont know which one is the earth as they keep blowing the fuses

I would think your best bet is to cut out the melted section and reconnect (through splices) the wires. They should be color coded, so you should know which wires connect together.

If you get the wires separated where the melted part is, spliced together, and properly insulated, which one is the ground really shouldn't matter. You have removed the point where the positive is touching the negative, and the fuse blowing should stop.

I would suggest you use heat shrink tubing to insulate the spliced wires.
