Calling those who are using the treehouse adaptor

[siexyy55]

THe Orca CD says that I need to pull 4 wires "through the black woven sheath" so that they go straight from the motronics to the tack, speed, a/c, fuel consumption under the dash.

So if I'm using a treehouse adaptor do I still need to do this??
thanks

no you dont need an engine speed signal to run the ac system
also tack signal is dependent on you e30 same with the fuel consup older e30 and m3 it goes through c103 plug newer e30 have it go though the c101
so buy one of mine....I will make it for your e30
