Welcome to TN! I found a toyota diagram for you. It's for a base corolla, but the link should allow you to select the trim level. Emblems can be found on this link also.

Thanks, those diagrams help a bit. Although, I was hoping if it isn't too much of a hassle, maybe someone can take pictures of how their bumper is mounted onto the car and I can use that as a guide to figure out what I am missing and how things go together. That would be so much better and easier for me to follow.

 

I figured out that the front is missing the radar. I've since bought the part. Unfortunately, the harness was removed with it. So, I had to buy that and now that I have it, I need some help figuring out where the 6 wires for the radar go in the housing connector. Here are some pictures:
Before I opened up the electrical shielding:

After opening up the electrical shielding the wires become exposed and I can crimp female connectors. They are color coded. I just don't know where in the housing they go.

Hi I have the same problem I'm missing the cable that you bought. Can you tell me what's the name of that harness that connects to the wave radar and where did you get it?

I really don't want to pay for something that I'm sure someone can help me with by just taking a picture of their harness.

 

Is there someone that can possibly help me?

 

You have been given links that are the best way for you to understand how to do the repairs properly. In addition to all the items in the parts fiche for the bumper other than the reinforcement, you will also need the front fender liners, liner clips, and most likely the engine undercover and fasteners as well. The link for tech info is the best way for you to learn how to repair the wiring properly. It may be less expensive in the long run to pay someone to do the items you are not able to figure out. But it's your vehicle, and you are free to do what you want...

 

Thanks, problem is I'm trying to do this as cost efficiency as possible because this car is going to sale. I'm trying to keep the price reasonable for the person buying it. I'm already $600 in parts and don't know if these online manuals will contain the information I need and be a waste of money. Honestly, I don't understand what's so difficult about taking pictures of how things are assembled. I didn't think that would be too much to ask for. 😕

 

Honestly, the best thing for now is to look at the diagrams to figure out what's needed. As far as I can tell, you need the radiator tray, splash guards, renforcement foam, engine under tray, grille, emblem, bumper, and fog light covers. Also need all the hardware to assemble everything.

Can't tell for certain if you have fog lights or not.

 

Yea, I don't think I have foglights. I appreciate the help I received, but it's not enough for an idiot like myself. I give up.

 

I use parts lists and drawings everyday. Order everything you can. When done, return what wasn't used. Or, the used route can sell you the entire bumper assembly as one.

 

the second picture, by the passenger front fender end, there is a clip that is on the drivers side where the bumper cover clips into place. that one is missing on your car, so you will need to get it

 

Thank you! That's one thing scratched off the list.

 

did you found the connector ??

Hello OP, I am in the same position as you were - need to replace bumper and all of the under trays (engine, wheel well, etc)

Could send me all the parts that you needed to replace? ...or any other tips, etc? Trying to figure out what all I need.

Thank you!
