Very simple request, and you would help me out greatly here

Go to your MAF mass air flow sensor its on the air intake

Open up your loom and there should be theses wires

In order

1.Yellow - MAF Sensor Signal
2.Black/White - Ground
3.Pink/Black - Ignition 1 Voltage
4.Tan - Low Reference
5.Tan - IAT Sensor Signal


One of the tans above should have a very faint white stripe, you may have to look a little further down the loom, once you find it tell me if that tan with white stripe is next to the pink and black wire or if its the last one.


Here's the situation, I have 2 wires that look identical,they use to sit side by side in a harness, More like use to be inside a harness, How can I identify them? there out of the harness and look identical.

I Figured if I could trace them to the actual ECM and find there pin numbers? that would solve it, but then where could I find ECM pin numbers?

Its out of my 2.2 L61 MAF Sensor (reason? to wire up the LSJ 2.5bat MAP for my SC install)

the maf center read as
1 Yellow - MAF Sensor Signal
2 Black/White - Ground
3 Pink/Black - Ignition 1 Voltage
4 Tan - Low Reference
5 Tan - IAT Sensor Signal

I need to figure out which is the Low reference and which is the IA2

i would buts 110 out and im way to comfy to get up....sorry.ahh **** it ill look

sorry im 2007 too but both tans on mine are identical,i even pulled the loom up about 4 inches and same thing pink the tan the the same tan no stripes on either

You have to really look close and further done the loom since it fades or even see if there's a difference in shading, thanks!

the way to be sure which IAT wire is which is to use an an ohm meter. Disconnect the black 14 way connector on the firewall near the brake booster(its on passenger side of master cylinder) You take your ohm meter and see which of those two wires is the one that comes out at spot "H" on the 14way connector. That wire is the wire that goes in spot "E"(the end) of the MAF

did you PM me on my site? I saw PM but cant respond on my phone during day and work blocks the site

EcoTecDriver

I did lol and thank you!!!

MAVEN!

I see no harness on the actual firewall, just the ones in front of the fuse box, can be a little more specific perhaps a picture?

I got it down, it was right the way I had it, it was reading 98*

Then When I swapped the tans to see if its wrong it read 300*


Thanks thou, but Im going to pm you my email I still want to know where this connector is
