I admire your patience mate. I absolutely hate wiring.

It is slow going......

Today I ran the steering angle, brake and clutch wires through the dash then got power to the brake switch so I could figure out which wire was which and connected the ECU lead. Also jumped of the hot for the clutch switch when it arrives. Brake and clutch are wired to the ECU, held on steering until I have a sensor. Heat shrink and wire wrap came this morning and resistors this evening so I was able to get the front wheel sensors installed. I wired the signal to the ECU but still need to do the power and ground in the trunk but the sensors worked out nice....they are universal, so 5, 12, 15, 24V which meads external power resistor and I prefer to keep that with the sensor than at the ECU end so should I change sensors I'm not rewiring the car.

I think this means I can put the cabin back together tomorrow....that would be nice after so many years.

Semi-related as it involves wires.  When I switched to the F430 calipers and rotors I also eliminated the power brakes expecting ITBs and big cams would make them worthless anyway.  as I was pulling the wheel speed sensor wire I noticed the brake fluid level wire just laying there looking lonely which got me wondering if there is a fluid level sensor that will work with the compact master cylinders I have?  A quick google search didn't find anything so the question goes to the community, anyone ever seen a level sensor for a setup like this?

A guy on grassroots says a mid 60 jag sensor screws on to those masters....I guess that makes sense as they were originally AP I think an English company . Best pic I could find and seems a most excellent suggestion

....and raised another question in my mind. The current caps seal the reservoir and use a rubber bellows thing I'm used to seeing on brakes....but newer plastic reservoirs with sensors, like the one stock on the 308 from '84 so not all that "newer" are not sealed...I guess the fluid has changed and no longer requires the air be kept out???? Never really thought about it before just now.



The bigger concern that popped into my mind is just how small these reservoir are and adding a float switch would take....1/3 looking at the pic? I liked these little masters because they at look like the ones used on the 308 rally cars, those were AP and more pricey but at a glance its period race race. I think they only hold about 2 full pedal pumps making brake fluid level checks pretty important I suppose.

speaking of which I opened the masters to try to figure out what size they were inside....this one looked like shit. I drained it, cleaned off the corrosion and refilled but man, the car has only been out of the garage to move it from 1 bay to another...don't really understand this. The other 2 looked find...I don't know.

Back on wires I went to put up the fuse box...hmmmm...wonder where I put the screws? After about 30-40 minutes of searching around the shop I dug them out of this box.....I hate when that happens but that's what happens when a project goes 13+ years I guess.

Here's a sight I have not seen in many years...a mostly assembled 308 interior.

There was a bit of soot from the fire....here's the water after cleaning 1, just 1 seat bottom, not the whole seat, just the bottom.

Then for those that don't know, Ferrari carpet is wool, real wool and apparently also really delicious,  Ironically the most damaged carper pieces are the ones I removed from the car so I wouldn't damage them while working.

Time for polyester? :lol:

You've been making a lot of progress. You taking time off work?

Trying to move through the list.....

The wheel position sensor are wired reading correctly.

The Oil Pressure transducer is wired and reading correctly

The water Temp gauge repondes correctly (same as oil pres, the ECU reads a modern sensor then drives the gauge)

The oil pressure warning light works.

The slow down, aka Malfunction Indicator works.

The ECU is now reading the OEM oil temp sensor which took a little thought as its an 8V analog setup and the ECU is 5V digital but voltage divider made with a couple 2.2K resistors I had did the trick....high enough resistance to be basically invisible to the gauge and low enough resistance to be basically invisible to the ECU which has a 100k 5V pullup on all the analog inputs.....a "5V pull up" is a connection to a 5V supply, usually with big number resistor so it generally won't disturb what its trying to measure but can make it easier to use the input for switches and such...but makes it harder to use the input with old school analog shi...items

I got the ECu to read the 8V analog veglia oil temp sensor and not mess up the gauge reading and not burn out the ecu input pin.......its simple little 2:1 voltage divider that cuts the 0-8V signal to 0-4V and is high enough resistance to be basically invisible to the gauge and low enough resistance to be invisible to the ECU.  Then resistors will break easily so I use the wire and heat shrink for structure......analog shi.......

Spent a little time staring at the pinout sheet in that last pic I posted....as I run out of pretty much every kind on I/O pin it appears to be time to optimize usage a bit better. Stuff like some digital input pin have pullups and some don't, the clutch pedal switch would love to have one, but the pin left for it doesn't while the front wheel sensors pins have pullups but those sensors don't need it. It looks like about 1/2 dozen pins should move.

Also the ECU has 2 built in WBO2 controllers but like everything in this ECU they need a model of some sort to be written to configure them. Last go I decided to not mess with it and just used a pair of external O2 controllers but now I think I'm trusting what I'm seeing from the NBO2 sensors enough to switch the WB sensors to the internal controllers. I think this is the last of the wiring items on the to-do list.....I'm going to need the block back soon.

What kind of wiring loom is that in the photos in this entry (that do not copy)?
Does this covering also shrink under high heat?
Where can I buy some?
