Hello chaps,

could really do with some help on a megasquirt system on me rover v8.

cheers

Hi Geoff.
Doe's this help.

Sounds like you're describing the relay board?



All the connections should be marked on the board itself. If it's the three on the top righthand side you're after they are (top to bottom) earth, ignition switched 12v, and permanent (battery) 12v.

many thanks chaps .. will have a look and see if i can work it out of the diagram
