Pic of proposed Wiring
noticed it cuts off the right side so here is link http://upload.3sgtemr2.com/files/1/MS%20Wiring.jpg
and a description of how I "think" everything should be done, with a lot of help from russ at DIYautotune(THANKS!) kit will be arriving any day and wiring commencing next week.
-G- to pin 17
-NE- to pin18
-NE+ will go to pin24 (first ignition input)
-G2 will go back to pin3 which would in turn wire to the lm1815 daughter card?
-IGT1 would go to pin36 via d14 as ignition output1 (R26 top edge)
-IGT2 I would run to pin4 via D16 as ignition output2 (R29 top edge)
Ok, So thats pretty straight forward, Now for the megasquirt mods:
