Fuse Panel Numbering

[Kaliv]

I'm was trying to replace my A/C fuses and found that fuse #9 is one of them. The diagram that came with the car however is someone incomplete. Could anyone help me figure out the missing pieces?

Relays seem to go in reverse order... F E D C B A.

The fuses look something like this...

?? - 10, 1-8
21

There is an 8 block to the right that reads left to right. But the block next to it starts at an unknown number and ends with 10. Where would fuse 9 be? And then fuse 21 is listed below, but I don't have anything there.

Car is a 1987 Coupe.

The various Porsche spec books seem to number the fuse block first one way...then the other way...to get you madly confused.

The 84-89 3.2's were basically the same but there were minor differences.

The square shoulder of the fuse block faces the front of the car, the slanted shoulder in back. So...the front-most fuse block has 8 positions, the next one back has 10, and the rear-most has 3. The Bentley manual counts the fuses back-to-front. Starting from the rear most unit, they are 1,2,3. This is called fuse block #3. The next block also counts back-to-front and counts 1-10. This block is called ( oddly) fuse block #1. The block closest to the front ( fuse block #2, go figure) continues this way and counts 1-8 towards the front.

For the A/C on an '87, block # 3, position 2, is a 25A, A/C fuse.
Block #1, position 5 is a 16A control unit fuse for A/C and heating.

The pocket Tech-Spec books identify the relays A, B, C.... front-to-back ( again...go figure...reverse direction of fuse numbering !)
