I've done some searching and thinking and I cant seem to figure out where the SAW signal needs to be on the relay board. I assume its on of the S* terminals.

The pip is to tach input correct?

It is wired just like the instructions say on the EDIS hardware site (which is down right now)

V2.2 MS board
V1.1 Relay board.

Depends on what connection on the Megasquirt you have the Saw connected. You can look at the relay board schematic and follow the wires out depending where you output the SAW on your Megasquirt. Common is to use X11 which outputs on the DB37 pin 25, then to the Relay board pin 25 and then back out on JP1-7. if you have a V3.0 board or you just want to run it this way, you will use DB37 pin 36, which outputs at the Relay board JP1-11.
