Replacement Of main fuse on 2009 mazda to do? Is is part of wiring harness?

The Japanese tended to use fusible links rather than main fuses. I don't know if they continued the use as late as 2009 but if so you will find two or three (probably) short sections of extra flexible wire situated close to the battery. These are fusible links and yes they are part of the wiring harness but are available separately, I believe, to be grafted in.

I have infrequently needed to do something with these and have fitted a large inline fuse holder and suitable fuse.

I suggest you begin by reading the owner's handbook supplied with your car. It should give useful information about such details.

Speed Sensor probably. Try:
1. Ensure mainshaft and countershaft speed sensors are installed properly. Disconnect mainshaft speed sensor harness connector. Using a DVOM, measure resistance between sensor terminals.

2. If resistance is not 400-600 ohms, replace mainshaft speed sensor. If resistance is 400-600 ohms, disconnect 25-pin PCM harness connector "B". Check for continuity between ground and 25-pin PCM harness connector "B", terminals No. 15 (Red wire) and No. 14 (White wire).

3. If continuity is present, repair short to ground in Red or White wire between PCM and mainshaft speed sensor. If continuity is not present, reconnect mainshaft speed sensor harness connector. Measure resistance between 25-pin PCM harness connector "B", terminals No. 15 (Red wire) and No. 14 (White wire).

4. If resistance is not 400-600 ohms, go to next step. If resistance is 400-600 ohms, go to DTC
P0720 (FLASH CODE 9) . Check for loose PCM harness connectors. Replace PCM with a
known-good unit if necessary.

5. Disconnect mainshaft speed sensor harness connector. Check Red wire for continuity between 25-pin PCM harness connector "B", terminal No. 15 and mainshaft speed sensor harness connector. If continuity is present, go to next step. If continuity is not present, repair open in Red wire between 25-pin PCM harness connector and mainshaft speed sensor
harness connector.

6. Check White wire for continuity between 25-pin PCM harness connector "B", terminal No. 14 and mainshaft speed sensor harness connector. If continuity is present, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary. If continuity is not present, repair open in White wire between 25-pin PCM harness connector and mainshaft speed sensor harness connector.

Can bad hub bearings make the abs and tc light to come on in a 2003 gmc yukon

Absolutely YES! The bearing and hub assembly contains the wheel speed sensor which is used by the Antilock Brake System (ABS) and the Traction Control (TC) system to see when a wheel is trying to lock up and cause skidding. The ABS will release the hydraulic pressure to the brake on that wheel and the traction control will reduce engine speed to prevent the wheel from locking up or causing you to spin out.
Many GM vehicles also commonly have problems with the wiring harnesses to the wheel speed sensors that can cause this same problem. The computer does not know WHY it cannot read the speed sensor signal. It only knows that it is not getting the signal and this is why the light is turned on. Before paying the BIG BUCKS for a wheel bearing and hub assembly, it would be wise to make absolutely certain that the problem is not being caused by a fault in the wiring harness. I have seen many mechanics automatically replace the wheel bearing only to find out that the problem still exists because they did not take the time to DIAGNOSE the problem. The fault code description says "Wheel Speed Sensor CIRCUIT fault." They see "speed sensor and automatically replace the sensor without actually checking the circuit. Not a problem unless you are the customer having to PAY for this type of guess-work!!!

There are wiring harness repair kits available for MOST GM vehicles just for this purpose.

I have included pictures of the bearing and hub assembly and the wiring harness kit to help you understand what we are talking about here.

Note the electrical connector sticking out of the hub assembly. This is the wires to the speed sensor. In the other picture, the connector at the end of the wiring harness is what plugs into the connector in the hub assembly. The other end of it gets spliced into the main vehicle harness in the engine compartment, after cutting the original harness out.

1996 mazda b2300 manual blowing # 24 fuse, the ignition,clutch,starter fuse every time i turn truck over. Giggle the wires under clutch peddle replace fuse and it starts right up..why fuse keep blowing?...

They may not need to be replaced but they need to be repaired. Somewhere under there in that wire harness you have a power wire that has a bare spot chafed in the insulation. You'll have to unwrap that bundle, the one you jiggle, and check each wire carefully for a bare spot. Start with any wire that is red,pink, orange; those are the normal power wire colors, but don't stop if you find one. There could be more than one. Just tape over the bare spots, you don't necessarily need to replace them. If the wire harness has beeen rubbing on a piece of the car try to reposition it so this doesn't happen again. Zip ties work good for this. Hope this helps.

I just replaced the wiring harness on a 1988 mazda rx7 and now the car will not star. the steering wheel lock had to be broken on the car to move it so the anti theft system that came with the car thinks...

you need the original black plastic key that came with the car lock all doors and make sure anything that opens is closed. then unlock the car on the driver door with the key. If you lost the key look in the owners manual hopefully the code on the key is written in there and then go get a new key made at a mazda dealer. Hopefully this helps. Maybe you can help me i need to replace my wiring harness and i dont know where the clear 4 prong plug is located under the dash on the main harness. i already unplugged the two orange ones and the two from the computer i just cant find the lear 4 prong one.
