    Just a heads up that they mangled the relay positions in the 308/84 OM and the 317/84 Wiring Diagram. Was contacted by a 1985 US Mondial QV owner who was getting some very strange (and incorrect) fuel pump operation behavior -- because he was using the incorrect relay positions shown in the 308/84 OM. Here's the summary:

    On the actual schematic in the 317/84 Wiring Diagram Fig 2 pages 8-9, the relay positions are shown correctly with relay i in the top row of relays and relay t in the 2nd row of relays:

    However, on page 3 in the 317/84 Wiring Diagram showing the relay positions, they have this wrongly reversed:

    And also in the 308/84 OM on page 103 showing the relay positions, they have this wrongly reversed:

    Thanks Steve - good title "PSA" - On my 85 Mondial Euro, I can't remember if I used the factory drawings or the ones from Afterburner but the pic below is what the right side of my fuse/relay panel looks like - need to check the updated Bosch relay #s to see if I have an error...

    The schematic symbols on those relays indicate that you are OK.

    Thank you ...and I just checked the wiring diagrams re-drawn by Afterburner and they are consistent with this layout
