1. Where can I order a new replacement harness for the ignition coils on a 2007 Camry 3.5 V6 as I live in the country and a mouse sought a warm place in my garage and chewed a couple of inches off a couple of the wiring harnesses to the coils, can I get a diagram?

2. Also, they ate through the vacuum lines and connector nipple on the air intake housing thus making it useless in trying to repair that part of the housing. I guess I really need a diagram so I can better identify the actual damaged parts.

Do you
have the same problem?

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.

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.

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.

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.

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 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?

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.
