Sorting the wiring harness

The wiring harness was looking worse for wear so it needed fixing up before installing.

A few nasty burn marks and melted shield:


Broken boots:


... and exposed wires!


I found some silicon Temptape from Car Builder Solutions that looked like it would do the trick of sorting out the wiring loom without needed a complete remake.


After giving the harness a good wipe end to end, it was a matter of covering every nasty spot with Temptape.





All in all a good result!

I then needed to extend the wiring for the throttle position sensor - so snip snip...

 ...join, extend and wrap...

...attach the sensor plug connector...


and cover it in Temptape.


Job done.

    Did you have any luck sourcing the part for the round plug that you had loitering on the new harness? I was checking out my spare harness (which is a bit shot) and realised that the part missing was still attached. It doesn't have the mounting cage but the part itself is there. It seems to be some kind of fake spark plug arrangement to discharge the ignition system.

    I'm wondering if the square plug that lives inside the car is something to do with the ignition amplifier which lives at the front of the engine bay by the drivers side headlight. I'll try and check some wiring diagrams and see what's going on.

      I've been looking through the wiring diagrams here http://www.cannell.co.uk/_manuals/porsche/p_944_wsm_electrics_from_88.pdf and I'm still not entirely sure what the long thin plug is. It may have something to do with the knock control though.

    Thanks Rob - I found the resistor that plugs into the round connector but I'm still stumped on the single row connector near the ECU and the spade connector on the end of the long thin wire that extends from the end of the harness!

Engine out the top - Easy Peasy

After reading numerous posts, the Porsche workshop manual and Clarks Garage step-by-step engine removal guide - I felt confident enough to tackle the job. But I wanted to remove the engine from the top.  As I discovered, it was pretty straight forward even for a novice! Result. I wanted to avoid removing the cross member and disturb the front suspension to do something I was convinced could be done easier from the top. Posts such as this one convinced me to give it a go at least. And I'm glad I did. In summary I was able to remove the engine from the top without needing to remove the bonnet/hood; torque tube; transaxle; bellhousing; clutch; clutch slave cylinder; cross member; front suspension; and radiator. Contrary to many so called internet experts opinions and many confusing threads this was painless and without dread. All that was necessary to remove was the starter; power steering pump and alternator (I figured to make the bottom of the engine narrower); intak

New Steering shaft bearing Nightmare removal

In my quest to tighten up the handling on the 944, I bought a new Needle Bearing from Porsche in an attempt to eliminate the fore-aft play in the steering at the top universal joint. The part number for the replacement is 477.419.059 and costs £88.86 posted from an OPC. Nothing like the effort required to actually remove the old one... I began the process by reading section 48 of Porsche Workshop manual. It appeared a simple enough process but two things bothered me: firstly, it required a chisel to remove a shear bolt (which in my limited experience never "shear"; and secondly a drill to remove two screws from the ignition lock. I was bothered because a quick look under the dashboard made it quite obvious that whoever had written the manual hadn't performed this task - well not without a dashboard in place that's for sure. I was bothered before I'd even started. Furthermore, the manual doesn't detail the replacement of this bearing at all - just the rem

Bellhousing & Clutch fork removal

Removing the bellhousing from the Porsche 944 engine is not as complicated as it may seem - such as in this situation with my replacement engine. When I removed the original engine I detached it from the bellhousing in the car and removed the clutch pressure plate bolts through the starter motor hole - see my other post for details . In this case I decided to remove the clutch fork pivot shaft bolt. Begin by removing the four 17mm bellhousing bolts - you'll find that the bellhousing doesn't detach completely from the engine. It'll feel like its hooking on something. That something is the clutch fork pivot shaft inside the bellhousing. The bellhousing will be loose enough to rotate - turn it 180 degrees and peek through the access port which is now on top - this is what you'll see: If the engine is still in car you'll be looking at this from underneath. The pivot shaft needs to be extracted from the clutch fork. It's held in place by a small bolt on the
