Wiring harnes swap for CIS-E3 (or other)

[ben swann]

Huw,

Were you able to remove the entire harness for the engine management.
or did you have to cut somewhere.  If I recall some of the harness
branches went behind the climate control box and was only after removal
I was able to get it out.

Also,  I thought someone had mentioned the CIS-E3 took the same MFTS as
the MC/MAC-11, but when I did the layout the other day using 87.5 GT
harness, the connector was the same as the 4KQ/GT sensor.  Are they the
same sensor?  That is CIS E sensor is same as CIS-E3?

Regarding the MC/MAC-11 harness, that will be installed in the Ur
Quattro I just got.  So I'll have to be interfacing that with the older
fusebox type wiring.

I'm sure to be hounding you with more questions then.

Ben
