MAF Extension Harness - Toyota Yaris Forums

ITA · 04-11-2017, 11:38 AM

I am working on turbo-ing my Echo. One issue I was facing was deciding how to extend the MAF wires to the location on the intake tract I am planning to place it. I really did not want to cut the original harness and splice/solder wires. As such, I did some research online and found an extension harness on Ebay for 5-pin Denso MAF's. The seller indicates that it works with other vehicles, including the Toyota Tacoma. After inspecting some pictures of the Tacoma MAF online and looking at my own, I decided to give it a shot. It works from what I can tell. If anyone is interested, please see this link.

I believe Yarii share the same 5-pin connection, so I think it should work, though it would be helpful if someone with a newer Yaris experimented with this as well.

Good to know! I'm always hesitant to mess with splicing wires in the engine bay. Salt + wires = fires.

Yeah, I thought it might be helpful information since we don't always enjoy relatively affordable plug and play harnesses like owners of some other cars.

BTW, how does the salt cause fires? Does it cause a short? Omaha salts during the winter, so I would like to know!
