Clay - the 3 relays are for main power, fuel pump and fast idle solenoid.

Charlie - I bought the relay board mainly to avoid hacking the OE harness early on. I'll get extra OE injector and distributor harnesses to use for the MS modification. I may not use the relay board when all is working, but I want to be able to easily get back to OE if things don't work as planned.

Since MS does not yet have IAC stepper motor control beyond CLT feedback, I plan to use the FIdle relay to control a secondary idle air supply when A/C or P/S is in use.... let the ECU control the IAC for temp and add more air via a solenoid when the A/C compressor or P/S pump kicks in.... don't know if it'll work, but it's what I want to try.
