2012 tundra secondary air pump replacement

ive had the 3 lights come on the dashboard. ordered parts for my tundra 5.7 limited. pumps are identical but the connectors are different. Every pump that i have searched for online has gray plugs with two wires and two prongs. my tundra has four wires on both plugs and plugs are differrent. anyone else come across something like this, cant find anything online

 

Are they black like these plugs?

 

Yes and my unit has the snorkel too

 

Can't tell on the pic but my plugs have 4 wires. Two thin and two thicker gauge

 

Looks like the part I need is made for a Tacoma. It has four wires and same exact plug.

 

At some point Toyota changed the system so it wouldn’t fail as often. Its definitely possible the harness changed too. I don’t know the specific year it changed over, it could be yours uses the new version or someone converted it after it failed? This is s pic of a 2021 harness for one of the pumps.

 

That's exactly the one I have in a 2012

 

So doing some research found out that there is an overlap between the years 2011 to 2014. In those years some trucks had either the black four wire a d some had gray two wire.

 

I have my 2021 set for sale for 200$ over in the for sale section haha. Removed when I put in long tube headers.

 

Curious as to why as I'm considering some AmericanRacingHeaders.

Interference or went with Hewitt bypass?

Sorry for the hijack.

 

Oh no problem. With ARH you choose if you want the air injection tube and I wanted to make it as clean as possible so got no tube. Then took out all the SAIS system to make the engine bay more empty. Definitely not a requirement and doesn’t do anything power wise.
