Just received my M160 today (Thanks, Todd!) and attempting to lay out and hook up the system on a test stand. I was hoping it was going to be straightforward but the connector on the end of the fuel pump cable is the wrong 'gender' for the ECU. Am I missing something here? The manual could be more helpful with a diagram of how it all should hook-up. There isn't even a list of items which come with the turbine so I can see if I have something missing...[

The RPM & EGT sensors, receiver connection, gas valve and fuel valve connections are understood but the two green multiplex connectors have me confused. I'm assuming the lower-right connector (Glowplug/Starter) goes to the turbine via the provided extension lead, leaving the remaining top-right connector. I have a battery AND a fuel pump to connect to this. Should there be another extension or 'Y' lead?
If someone has a detailed picture of a test-stand setup I'd be pleased to see it.
Thanks, Andy

Andy,
You have received one of the first batch of MK2 Merlins. The manual still relates to the MK1. We are updating the manual to reflect the changes now.
The fuel pump should have two plugs on the lead. One plugs into the ECU in the slot you indicated, the other is the battery connection.
Does this clear things up?

Thanks for the reply Todd.
Well, it looks like I have the wrong fuel pump (the mk1 type?). It has only one plug.
How can I get it replaced quickly?
Cheers, Andy
