Making WSM wire traces visible

Ah, I haven't had the pleasure of seeing the front of my engine yet (except in previous-owner photographs), so I put it on the left. Having said that, I forgot to reverse the lower one. And how I got the correct left bank/right bank positions is another matter (I think I assumed most of the left bank stuff was removed and worked backwards from the 5.2)

I realised after looking at my wiring a few days ago, that adding colours to the engine diagrams really serves no other purpose than to help trace the wires on the diagram itself. The harness is, for the most part, sealed, so colours cannot be determined. Also, seeing completely different colours on the real O2 sensors, I had to add some further detail. I also found the wrong (1~4/5~8) decals on my coil packs, so I ordered some through Ricambi (Talk about fast service... ordered on Friday... Fitted on Monday... in Australia)

I've modified my original diagrams to match the pdf...

Cheers

Latest update... (gobbledegook to most)

Major Update #3

Incorporated the details of the two Bosch ABS wiring diagrams into one. Also added a jumper wire to the ABS power wires as described in the WSM for cars without an ABS cutout system (USA, Canada and Australia). Connector graphic added to help identify pins on connector "40123" (aft of left rear shock absorber).
Unknown: Internal wiring of the ABS cutout electronics unit "10009"

Reversed the pin numbering on connector "41019" in WSM wiring diagrams 5 and 6. "12~1" is now "1~12". This removes an error in the original workshop manual diagrams where the aircon compressor pin was given different numbers in different diagrams, and also allows an elegant match of wire colours to pins on the real connector (on 2.7 and 5.2 cars). Connector graphics added to help identify pins on "41019".

Corrected tacho backlighting wiring (partly my fault.. the connections were blurry in some of the original diagrams)

Unknown signal on brown/black wire attached to 5.2 ECU pin 80 identified as an engine rpm source for the tachometer (on the instrument panel).
Unknown: How does the F1 TCU get this rpm signal? Splices?

Fig 6 HVAC wiring diagram Fan Power Control Unit (10008) doesn't identify the pin order on plug "B". I've assumed "4,5,6" to match the Workshop Manual notes (Volume 3/I-26). Graphics altered to match plug orientation on actual unit.

(P.S. Sorry, John.. more work for you )

 

I see in Fig 3, there's a sidenote which says that the left hand fuel pump was removed on later cars. I'm pretty sure they mean the right hand pump (In the sidenote, they use the right pump ID number).

The Ricambi parts diagrams show very short lines from the left hand pump to the fuel filter on the single pump cars.

Zipped gif diagrams updated....

Update 10003


Also:
Errors corrected on Fig 3. However, the relay marked "E12/R" ("circuits energised by ignition" appears to have no earth except through the starter solenoid(!) and power on both sides of the relay coil during start. Any expert Ferrari electricians on the forum?

Currently working on a 5.2 version of that diagram.
