Where do these MAF wires go?

[unkillablepaseo]

I am a bit confused on what wires go to what. I have gone through the TSEM and I have figured out what the wires from the plug are along with their color. but I can't find what the colored wires from the main harness are or connect to. Basically can anyone take a peek at my pictures and tell me what wire goes into what?

Thanks everyone:1zhelp::icon_bigg

Looked at the tewd's for 88- and 89+. Don't see all those colors for the MAF(colors to MAF remained unchanged thru the years.).
Only yellow wire I see going to the ecu is for FP. Can you unwrap that tape a bit farther to verify nothing was spliced higher up?

Yes sir! That is the exact problem I face. Well at least now I know that the MAF wired don't change. I'll check the wires a little higher. The car is not mine so I have little knowledge about its history

Ok, so I unraveled the wires to the point where it starts to cross the cam covers and that yellow wire is indeed a toyota wire. I eventually fixed the MAF wires by switching themaaround till the car fired off. (very unorthodox but hey, it worked.) This is how I wired the wires in case someone else has a problem like this too.

- the brown wires go to brown, I don't know how to tell what they are unless they are still attached to the plug. ( BRN either E1 or E2 )

- Blue with Red stripe went to Blue with Red stripe. ( L/R aka. VC )

- Light Green with Red stripe went to Yellow. ( LG/R aka. KS )

- Light Green went to Blue with Yellow stripe ( LG aka. THA )

I don't get it. Since the TEWD shows the colors why not just ring the wires out at the ECU? Simple...

Look man, I'm gonna be honest..... I'm pretty much an idiot with wires and harnesses. The car isn't mine, I have little history on its molestation. Those wires on the harness loom pictured above were indeed connected to that cars original MAF plug. Reason for replacement was that a couple of the wires got hard and brittle and we're broken from the base of the plug. When I cut the bad plug off to replace it with a good one I assumed that the wires would all be colored accordingly and I would have no problems however, that was not the case. By the time I caught my mistake it was too late and the garbage where i put the bad plug was picked up by the garbage truck.

Now I looked about as good as I could in the TEWD and the yellow wire has a lot of people stumped. ... according to the manual the yellow wire goes to the Fuel Pump. But when the car arrived at my shop (Running on all 6)(Also I am a non professional) the wires above were connected to the MAF.
