Thanks for the feedback - I have no red relay on drivers side nor anything with a knob to turn, but on the passenger side behind the firewall cover behind the battery I have the Klima Relay, and two others one large black one that starts with 004 545 and says 6 Zyl Diesel & ELN Control on it in front of the Klima (same size as the Klima) and then a square relay to the side that with a clear cover. All the connections are fine as I removed and replaced the relays.

The other thing on the passenger side behind the kick panel on the floor next to it there is a connector point but no electronic control box so it appears I don't have an EDS module so I either have a basic control system or they hid it somewhere else.

I have the 603-912 engine micro fiche (just need to gain access to the reader) so that is the next step in this adventure.

Thanks for the assist Jim and it is appreciated.

Carl
