It was a bit more of a frustrating and lengthy path that I would have hoped for to get this figured out, so I thought I'd help others out by spelling it out as clearly as I can.

If you intend to run a Holley HP ECU with a Racepak IQ3s - this is what you need.

Holley part number 558-412 (~$70)
Racepak part number 280-CA-EFIHOL (~$75)

I had a range of responses from Holley tech from, "only need 558-412", to " you need 558-412 & the V-net module ($375)". Some of the confusion is in the fact that earlier Racepak dashes required the V-net module ---the IQ3s does not require this item - just these two adapter harnesses.


Maybe this will save someone else a lengthy conversation. Ultimately Racepak tech got me squared away. I asked them to send a message to Holley's tech group to clear up the confusion as well.
