Really just getting away from it to go back to DBW. Also was informed my cam grind is more suited for big plenum and long runners of an OE architecture intake than this dual plane short runner deal.

Got same question in PM from other people, I should have posted reply publicly..
Since the two levers are tied together and operate simultaneously, throttle position on one will be throttle position on the other, right!? So just run typical ls1 harness to only one of the TPS sensors.
As far as IAC, I had planned to try to just make it run/idle with just one hooked up. If unable to tune that in, then figure out splitting to connect to both, however I'm optimistic I could sort it out just commanding one IAC. Worst case cheat the throttle plates open a tiny tiny amount on the TB that isn't getting it's IAC commanded.
Last topic on IAC, Holley used Chrysler IAC on these that are physically identical to LS1 IAC, however pins A and C are switched internally. So two choices to remedy are simply switch the two pin in yours harness at the connector, or unbolt these IACs and install LS1 items. I personally planned to just swap the pins in the connector.
So the overall answer is that no special wiring is needed.

Thanks, but I found the manifold and TB dimensions on Holley's website. Gotta add some for an air cleaner, too. This would be going into an LS1 powered Austin Healey sports car. It's pretty tight. I'll look at it tommorrow.

The ideal IAC setup for that would be to use the one that I use on my roots blower by Blower Drive Service, You could plumb the two IAC ports into one IAC valve.

Sorry, but it won't fit my car unless I cut a hole in the hood which I don't want to do. It's too tall by at least an inch, maybe 1 1/2" and I can't lower the engine any more without hitting the accessory drive. Sure would have looked good sitting under a Cobra style air cleaner, though.
