G50: ENGINE HARNESS ASSY - Which One is Has MAF TPS Connectors

[lino]

Can someone please tell me which one of the harnesses has the MAF connector on it and which one has the TPS connector on it?

This is all the information I was able to gather so far:

24079+B ______ HARNESS - ASSY - EGI , SUB (RH IGN COIL)24079+A ______ HARNESS - ASSY - EGI , SUB (LH IGN COIL)24079 ________ HARNESS - ASSY - EGI , SUB (KNOCK SENSOR)24075N _______ HARNESS - ENGINE , SUB (INJECTOR)24077M _______HARNESS ASSY - ENGINE (Battery - Positive cable)24077P _______ HARNESS ASSY - ENGINE ROOM SUB24012 ________ HARNESS ASSY - ENGINE ROOM24078 ________ HARNESS - ASSY - EGI24171 ________ HARNESS - AIR BAG , ENGINE ROOM

Unfortunately I was right. there is no sub harness for the MAF and TPS sensor. Its all one big harness that links the ECU, and all the sensors, switches and actuators together as one.

You could replace that entire harness but trust me it would make my tweeter install experience look like a walk in the park with a hot blonde.

Too see a better picture of what I mean look in the 1990-1993 Q45 FSM page EL-158.

Sorry buddy.

But I am sure you can replace all the problematic connectors.

On an another note the harness: 2407264U00 is $45.38

[Q451990]

I can't imagine that harness would be that cheap.... the injector subharness is way more than that!

Here are the pages from the FSM. The Engine Control Harness appears to be the one I'm trying to find. So which part number is it in FAST (from the first post)?

Through process of elimination I'm not sure that this screen has the ENGINE CONTROL HARNESS that you need. Are the blue names next to the P/N's your typing or FAST?

The FSM pages that are attached show 8 harnesses and sub-harnesses and your list above only has 6. The last one, HARNESS ASSY, ENGINE ROOM, only passes through the engine compartment and has no connections to the engine.

The harness you need is the main Engine Control Harness. What's listed above are engine control sub-harnesses (4) and engine room harnesses (3).

Look for Harness- Assembly- EGI.

Mine. I hope I got them right.

I just added some more. Thanks.

I believe you've found it.

24078_______ Harness - Assy - EGI

Notice in the drawing how it starts on the right side....at the ECU inside the passenger compartment.
