Hey guys, I thought I took a picture of the wiring at the back of the engine, but I did not.
Now, I am not sure which plug connects to the MAP and which to the barometer, neither is labelled.

I just did the l26 UIM/HV3 swap, so I am trying to figure out which cable I need to move/extend to reach the new MAP location.

Looking at my harness, I have one that comes from near the alternator, and another that originates near the EGR valve.

Service Manual doesn't show which is which, just generic photos.

If you know, please assist.. Will be buttoning it up tomorrow night hopefully!

Here's the mess, well, lunch time vs dinner time.

i believe the one that comes from by the alt is the map

Why buy something sensible with a RWD setup when you can build something really stupid, like this

I did a test setup (just plugging in and turning the car over) to see if I could cause a fault code. Nothing happened, so I did in the manner that you described above. I extended the cable 1 1/2 foot to the L26 UIM passenger side so it's more like stock.

Thanks for the reply!!!

Killer! Glad to help
