Somebody please verify the matrix below. I am using a MS II V3.57 and a relay board. I wish to control a GM O-ring style 4-pin IAC. I ran the resistance test and found that the IAC is wired as in the second example in the manual (coil 1 connections are adjacent). I would appreciate a double check on IAC to relay board connections.
Thanks
Jim S.

Re: IAC to relay board question
Jim, I'm sorry I can't verify your connections, I'm assuming that you've already verified. I'm just wondering if your setup is working. I'm running the 2.6 firmware, and Matt from diy is advising me to upgrade to 2.881. Just wondering how it's working for you.jshep wrote:Somebody please verify the matrix below.
