I need to get a threaded IAT sensor for my LS1 swap. I am using the Holley HP EFI harness. Im not sure if I need a special IAT sensor for the connector on this harness or does any gm IAT sensor connect to this harness? Does anyone know what sensor I need. Thanks.

Wish I could help you, but the HP EFI package I got came w/ that sensor.

Your stock IAT sensor should work, The Holley system is plug and play for the ls1 providing you have the correct harness.
You can also use Holley PART# 9920-107 and I haven't tried it yet but I was told the Fast 307004 Air Temperature Sensor works also.

Thanks for the reply. I didn't have a stock sensor to go off. I had to change my stock oil pressure sensor because the connector on the Holley harness was different so I wasn't sure about the IAT sensor. I'll chech out those part numbers.
