BB IAC question
I've just purchased a BB TBI and the IAC is mounted differently. Instead of screwed in like my SB, it is bolted on with 2 screws. THat part is no big deal but the connection is different. My SB has four pins, 2 on top of 2. The BB unit has 4 pins in a single row.
Anybody know of an adapter or the part number for the BB unit and how the wires would correlate?
TIA

I bought the pigtail connectors for the IAC and TPS sensors from one of the guys on this site that collects them from junkyards. If I remember correctly the wiring colors used were the same.
