picture is worth 1000 or more words! I scanned the pages. HAndy for others to see also.
one set is for the EZK..the other is for the LH.

As always Tony, great job!!
This is a common failure on our cars and everyone should check to see that theirs is working properly.
I had 3 used ones in my hand at one time and on 2 of them the idle switch was totally dead and the 3rd one worked intermittent. I can't remember if the WOT part worked on all of them but I remember some issues there as well.
When I first installed the stage one kit on my wifes car it worked near perfect right out of the gate. Some of the Milwaukee guys arranged a dyno day down in Milwaukee and I joined in. All the way down there the car ran perfect. The passing power is flat out impressive. I get the car all strapped down on the dyno and go to make my first pull and the car WOULD NOT come out of stoich. No enrichment whatsoever. Finally give up and take it off the dyno and we all went to lunch. On my way home I'm kind of goofing around by accelerating hard and backing off. Some times the AFR gauge would climb lean and some times it would go rich like it is supposed to. By the time I got home it was working perfect every time I accelerated. I pulled the connector off the LH and sure enough, I would occasionally get a non working WOT signal. I think the idle switch is more of a failure than the WOT but just the same, you should check to see yours is working.
This is just my experience, I'm sure Jim Bailey can add a lot more information on what he has seen through the years.
