Westfield MX5 Wiring Harness
I recently built a megasquirt using the Westfield MX5 guide but I used the DB37 connectors instead of soldering the OEM connector to the board. I was planning on using the pinout on the Westfield site to make a wiring harness. I was wondering if I need to wire anything differently to use a wideband O2 sensor and an IAT sensor? Also, does anyone know what the orientation of the OEM connector is in the pinout?
I couldn't get the picture to save as a JPEG so I just linked it below:

If I may make a suggestion, I install the transistors first. That way it is easy to measure for shorts (diode test) without other components interfering and giving false readings.
Also, I don't use a MS output to active the main relay for the MSM. I use 4S as the input for an active low circuit to ground 3H. Iow, any car that has 12V on 4S gets a ground on 3H.
Very professional page btw, congrats!
