Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Hi there,
Having some issues with my car. Was wondering if you had a chart around like the ones at this link: https://www.2carpros.com/questions/1996-toyota-camry-le-diagnostic-code-p1300

I need a wiring chart for the ECU so I can figure out which one are for the fuel injectors so I can figure out if the wires are corroded.
Thanks!

What are the issues you are having? If none of the injectors are working it is not likely to be on the ECU side. That would be on the power feed side. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Need to remove engine wiring harness

if you want to pullit out with engine it should connect to firewall with a screw in center or clamps on either side. if you are disconnecting from engine remove th connectors and clamps holding it in place on engine as well as body. these can either be screwed down or just a clamping device.

I am needing either detail wiring diagram or real pictures of maybe the back of the fuse box that's inside the engine compartment. I'm having trouble finding where the wires go to from plug to plug. it happened when a couple of them got pulled out and I do not know where they're supposed to go to now.

I searched through all of the available service information for your vehicle and there are no diagrams that indicate which connectors go where. Typically however, those connectors are all "keyed" a certain way so they will only go in their designated sockets. From the picture you attached, that appears to be the case here. No two sockets on the back of that fuse box appear to be the same. Try plugging them in and let me know how you make out.

No, the problem is not the actual plugs where they go into the plug the fuse box it is the wires that go into the plugs. I'm needing to find out where the wires go into which plug the wire colors and maybe if at all possible where the wires go into the plugs itself.

I found this wiring diagram for you. Let us know if you need anything else.

That's all that's y'all sent me the diagram which was very helpful to me, but I was wondering if they had maybe an actual photograph of the bottom of the fuse box where I could see the plugs where each wire went to that plug. I could find out exactly what wires came loose out of the plug itself. but you have been very helpful all y'all and I appreciate the help.

Hi,

I found you fuse boxes top and bottom let us know if you meed
any else.

Thank you

I am needing more of the wires. I have I know where the the plugs go and basically the colors and kind of what they're too. with more or less the wires that go into the plugs .some of them pulled out and I'm having trouble placing where they go into. what plugs and what color wires some of them were brittle and frail and and broke and when two of them broke on the same plug I don't know exactly which place each wire goes to. if that makes sense. the oil I really appreciate your time and effort towards helping me.

I need the wiring diagram for the wires under the engine compartment going to the main fuse box the green one. I have no idea where it goes the red and white striped one that is spliced. I have no idea where it goes and there's a wire coming from the firewall it's black. I don't know where it goes. if I could get a picture of the fuse box and where all the wires go from the plugs to the wiring harness that would probably save my marriage and my life.

Hello,

In the diagrams down below I have included the wiring diagrams for your vehicle's Power Distribution to the fuse panel as well as the Engine Management wiring diagrams for your vehicle. Please go through these wiring diagrams and get back to us with how everything turns out. I hope that these wiring diagrams help.

Thanks,

Hi,

All the wires power and ground wires are referenced to each connector; find your wires in the wiring diagrams the wire will be colored coded with a connector lettered and numbered terminal. The letter means the connector and the number means were the wire is placed in the connector. Example there may be a blue wire with yellow stripe and it will marked in the wiring relay connector C4 that would be the C connector/terminal 4. Each relay and fused circuit is connected to one of the fuse boxes the wiring diagram tells you where the junction box is and every connector is lettered .You might already have some of these wiring diagrams I'm attaching below. Please let us know if this information. was helpful and if you need more help.

Thank you

Thank you so much for the information. one more question maybe it is the crank shaft position sensor under the alternator and a red wire runs from that to the fuse block. where does that go?

Where does the red wire run to? I need help.

Hello again,

I do not have the vehicle in front of me. Where component does the red wire go to?

Thanks,
Alex

I believe that it goes to the crank shaft position sensor and also ties into I believe two other sensors the colors are black and red . The red wire ran across the top of the motor and ran into the fuse box shoved into the relay for the ac and I was trying to put it where it is supposed to go. I have spent the better part of a month trying to figure out how to run the wires to the correct location. You solved this problem in less than two minutes for me which I am grateful for. We are a family of 7 and we have been without transportation for almost two years and got blessed with basically a brand new 1989 Camry and I knew about the electric issues. Me only doing my best at everything I do could not allow the car to stay rigged with the precious cargo it will be carrying around. I have had everyone around me doubting my ability to fix it in fact rumors of sabotage which is ridiculous because that's my transportation too. You bailed me out with the diagrams which I am grateful for and I hope the good lord blesses those responsible for the site. It has changed our life on multiple levels and took me from a dark place of not knowing to the light full of the right information thanks to you. Thank you so much for your help without it I would have went directly down the toilet of failures. Thank you and God Bless.

I also need to know where the tubing from the bottom of the charcoal canister goes to. it currently rest on top of the transmission going to nothing and venting the oil all over the engine compartment. And also when I purchased the car the power windows and door locks were and still are not working. I could really use the help again.

One more question. could you give me a game plan for removing the 3 spark plugs under the intake manifold? You are the man!!

The last hurdle I have to overcome is the two plugs going into the back of the fuse box. one is orange in color the other one is black with four Spades coming out on one side and 2 on the other both plugs separated 2G and to 2J are in question. if I can understand plugs G and J the orientation of the wires and the color I could figure it out they both have spaces for 6 wires going into the plug itself . there's only five in each I believe that two wires are missing and that's the problem why won't it wont run. I believe one wire might be the am-2 red and white wire coming from the fusible link. any information would greatly be appreciated. thank you and have a good night.

One more thing I have not tried to turn the car on yet but there's two switches they go from the EGR valve tubing to the block and it's almost like a brass plug with two outlets for small breather tube. I guess can the car run with those not functioning properly the problem is one's almost $100.00 and the other was about $75.00. I can't really afford it right now. I don't know if those switches has to function properly for the car to run. thank you and that will be it for now.

Hello,

I have included the Junction Box 2[J/B 2] wiring diagram, and a diagram of the layout of the J/B with callout, as well as a diagrams of your vehicle's electrical connectors and a power distribution wiring diagram for your vehicle as well. I hope that this helps, and please get back to us with how everything turns out.

Thanks,

I forgot about the last question what is the meaning of life?

To live! :) we only handle one question per thread so please start new question for the out of subject problems.

okay, I have a red wire coming from underneath the alternator on a 2.5 V6 and I believe that it's connected in series to maybe two other sensors. I'm wondering if it was ran across the top of the engine to the fuse box and they put the wire into a air condition relay. I was wondering where that particular wire it's supposed to go to. I believe that it comes from the crankshaft positioning sensor the other wire is black and it's grounded to both the frame and the engine. thank you so much for your help.

Can you take a picture of what you are talking about? also check the fusible links near the battery.

Can I get a picture of the plugs that go into the back of the fuse box? they're different colors and different sized. I need to see the wires that go into that including the fuse box with the relays.

Hello again,

Okay, in the diagrams down below I have included all the wiring diagrams for your vehicle that include a relay and I have highlighted all of the wires that go to the relay. If you look at the wiring diagram there will be a box around the relay and on the side of the box it will tell you what the relay is and it's location on the vehicle. I have also included a diagram of a typical 4 pin automotive relay with where the wires will be coming from for your reference, as well. Please go through these guides and get back to us with how everything turns out. I hope that this helps.

Thanks,

have a 1993 toyota camry 4cyl and the problem is only 7.1v to the fuel pump connector and therefore the fuel pump isn't working. Need a fuel pump wiring schematic to figure out next step. I have verified all fuses are good and volts are good, replaced plugs, wire, dist cap, rotor, ignition coil (which is inside dist), fuel filter, and even the circuit opening relay (which is above the glove box) and still not getting enough juice to the pump. Any ideas?

Hello,

Here is a guide to help you test the wiring of the fuel pump and relay below the fuel pump relay is the EFI relay.
