When you get these files, they are really too small to read easily if you print them out on 8 1/2 X 11 paper. You can have them printed on 11 X 17 paper, a little heavier than bond. I uploaded mine to my local UPS store, and they had them done before I could drive down to fetch them, total cost about $3.
Now they are a useful size. Fold the 11 X 17 sheet in half, so it is 8 1/2 X 11. Then with the single edge at your right, fold the top part to your right, in half again, so the sheet makes something of a Z shape. Now you have diagram sheets that can be hole-punched, placed neatly in a ring binder along with 8 1/2 X 11 inch sheets, and easily pulled out flat for reading, just like the ones in the original shop manuals.

Hello, is it posible to get 993 year 1996 ignition wiring. I have no spark. I find 1995 wiring here on the forum but seems to me it does not match pin numbers on DME etc. From the car observation it seems to me the 1996 model do not have ignition module under the seat and the DME is connected directly to the coil in the angine area. Can you confirm?

The DME relay is a common failure point, you might want to try replacing if you haven’t already. It is located in the fusebox in the front trunk.
The DME itself is under the driver’s seat in my 1996. If you remove the seat and the DME box isn’t there, the previous owner may have installed an aftermarket engine control system.
You mention something in the engine compartment that connects to the ignition coil, i’m don’t have access to my 993 just now so i can’t visualize what that might be - any chance you could post a photo of it here?

I’m sure BobbyT or someone can get you a wiring diagram. The 1995 model has OBD (on board diagnostic system) I, while later models have OBDII - so I suspect the wiring is slightly different. But all 993 models have the ECU (electronically control unit) located under the driver’s seat. The DME delay is located on the fuse box in the frunk. It sounds like you may have some aftermarket wiring...
As noted above, the DME Fuel pump relay is a common failure point. The engine will turn, but there’s no gas to ignite.
