Just my 2 cents mind you........

You will need a minimum of 2 relays. One as the master and a second one for the fuel pump. You may want to add additional relays for other functions.

As I mentioned to you in your previous post on this topic, you will need to take a look at the external wiring diagrams in the manual for the specifics regarding wiring your aftermarket board.

Just a quick followup.

The MS3 external wiring diagrams can be found here: http://msextra.com/doc/ms3/hardware.html#wiring

Also, as I pointed out in your previous post, it might be better to post your MS3 questions on the MSExtra forum.
