Is it true that on 94 Engine harnesses C105 does NOT exist ???

Can't find that connector ANYWHERE on my 1994 wiring harness ...
Looked up the wiring of that connector on Shoebox and only 2 wires would be usefull as the rest are for TCS control.


Anybody ?

that is correct, on 93-94, there is only 1 connector on top of the pass shock tower connecting the engine harness and front body harness, there are 2 connectors 95-97

Ok, thanks !

Found out this bit of info in the proces.

On the 94 LT Blue wire represents the TCS active signal, while on a 95 harness it's the PCM power feed.
The 94 Harness gets that feed from C210 where the 3rd wire is an Orange one and feeds the PCM.

On Shoebox it's lists that position as empty for both the 94 and 95 models, maybe that can be updated.

I don't really understand what you are saying. Explain more. What is listed on my site is out of the factory manual.

Though the 94 manual talks about TCS, I didn't think it actually appeared until 1995.

Indeed !
Well, my 94 engine (non vented opti) came with all wiring and i noticed that the C210 (black) connector has 4 wires connected to it, on contrary to what's mentioned on Shoebox for the 94 and even 95 version of the C210 (one slot is empty, so only 3 wires instead of 4)

In fact the Thick factory manual doesn't even list the wires of C210 ... Where (what page) did you find it ??

Too make a long story short, mine has 4 wires .. The orange wire is the extra one not mentioned anywhere, and it just so happens to be the PCM feed wire which is lacking in C100 in the 94 harness (is present in the 95 C100).

I have verified that info in the book and changed the listing.

Some info on my pages is from scouring individual manual pages and listing the data. I might occasionally miss some (not on purpose). The manuals have been known to have occasional mistakes of their own.
