Need help on part number

Just wondering if anyone can help me find the part number for the wiring(white color) that goes from the battery to the starter. I attached a picture of the wire I'm talking about. My car has had a few rare times problems starting, battery is good, terminals are tight and clean. The majority of the times people replace the starter but there is a component that i read that is wise to check before buying a starter and is the wiring i mentioned which gets corroded and starts giving problems. The mechanic told me to check this before purchasing a starter and when i did, i noticed the cable has corrosion color green and blue, so i guess this is the problem why my car a few times has had problems starting. I checked for the part number to this harness or wiring but wasn't able to find it so if anyone has the part number that can share it with me I'm going to appreciate it. Thanks in advance!

 

Chances are that is part of the harness so the only way to get that wire is to get the whole harness.

If the terminal is corroded you can buy a cleaner/use a wire brush to clean it. If it is too damaged where the wire crimp is then you can cut the terminal off and crimp a new one.

 

What is corroded is the wire itself not the terminal. Do you happen to know that part number for this whole harness?

 

Its easier to just crimp in a new section of wire tbh. Ask me how I know...

 

How do you know? lol Can you explain to me exactly how you did it please

 

I know because I had the exact same issue. Rough plan/steps below.

Tools needed:
crimper (A ratcheting / pnuematic one. NOT a vice grip etc etc)
wire (measure the existing wire and get proper size)
eye fitting
splice fitting
cable cutter
marine grade heat shrink (and heat source of course)
Volt meter

Process:
- Cut and prep (both ends) the new cable. Apply the eye fitting with crimper. Apply the heat shrink and shrink it on.
- Cut existing cable far enough (~6-8 inches?) from the existing eye fitting.
- Strip back coatings on existing but cut cable far enough to apply the splice fitting. Apply heat shrink that is long enough to have at least ~.5" beyond the splice fitting.
- Crimp in the splice fitting between existing and new cable.
- Test continuity and jiggle the cable a bit. If good, screw the new eye fitting back to the battery terminal fuse.
- Locate heat shrink and shrink it.
- Profit.

 

Thank you so much for such valuable information. You saved my day because i was informed today by the dealer that this is the emissions harness which cost a fortune and a half and that this part is discontinued by mazda. I couldn't believe it when they told me but i wasn't going to spend almost 700.00 for a harness.
So to get things straight here, what has corrosion on the cable is the far end of cable closest to battery terminal? I thought the whole cable was corroded. thanks once again for such valuable information. The only thing that concerns me is the wire gauge diameter

 

Probably 6 gauge or 8, if you measure the exposed copper you can compare it to a shaft using the diameter and get it that way. Alternatively if you have a second hard to run around with, take the wire off and take it with you to the store.
