Ok so I just got my new ms2 v3.57 I had it assembled and modded by DIY autotune. I need to make my db37 harness but I can't seem to find a schematic on how to make it. Anyone have any links for the harness making of the db37 and the 15pin serial?

Have you looked at the mega manual or read any of the stickies in this section? If so you would have seen how to wire that in multiple places.

Yes I have. I haven't found anything for the 3.57 board though. I only come across the 3.0 or 2.2 and nothing on the 15 pin

really?

I only see one tach input. Where do the cmp and ckp signals from the as go?

PIN 24 of the db37 would be your crank input.

any of the four spares, or four IACs, or spare pads can be the cam in.

They must likely wired it so pin 25 is the cam input, but I'd confim that with them as there's probably 50 combos of different ways you could mod it to work.

Ok thanks that makes sense now
