Hey everyone. I'm currently in the middle of finishing up the build of my MS3x which will be installed in my 2001 SE. I've been following Frank's instructions (99-05 MS3 with MS3X | My Westfield MX5 99-05 MS3 with MS3X | & Megasquirt site
). I also purchased an alternator control circuit from Braineack to keep things neat inside the Megasquirt box, which has worked out quite well. Everything appears to be working great (according my testing with a JimStim) and I'm just about done wiring up my harness. My only question at this point is the proper connections for A/C control. Doing a search, I found information for everything except 01-05 and Frank's pinouts on his site only have the ac fan labelled on the 01-05 pinout chart. Looking over the schematic (https://lh4.googleusercontent.com/-O...pg?imgmax=1024
) and a pinout chart, here's what I've come up with:
ECU - Description - Megasquirt
2C - condenser fan - Extra injector output
2B - main fan - MS3X Nitrous 1 (pin 24)
2K - a/c switch relay - Extra injector output
4F - thermoswitch / pressure switch - MS3X Tableswitch (pin 28)
Just for kicks, here's a few pictures of my build:
DIYAutoTune's new NipponDenso 122 pin DIYBOB is REALLY nice. I love the fact that they put in two rows of pin connectors, which helped tremendously when wiring up the 1N4001s flyback diodes for the IAC and VVT circuits.
Any help to confirm the above would be greatly appreciated. Thanks in advance!
