Default 4150 Throttle body questions

Hi everyone, I have a few questions about this Throttle body that will be used on my new vic jr intake.

1: what is this port for:


2: I just want to double check that these 2 ports beside the IAC sensor were just vaccume ports for Ac, brake booster..etc


and 3: most importantly, this was designed to be used with a 1990 5.0 mustang TPS, but I think the 1995 impala one might work. Any ideas if there are any kits that will allow my ls1 TPS to bolt onto this?



thanks in advance for any help

here's another pic, this thing looks pretty sweet..

I think #1 is for a MAP sensor.

#2 center is for an IAC(4 wire stepper), don't know what the two outer ports are.

Cant help on the TPS.

Your mount setup looks similar to that on my no-name special. I used a spare TPS (& IAC) from from my '87 GN engine and needed to re-pin the connectors to fit the Holley harness shells...

It does on mine, but there are either stand-offs or spacers that make it stick out about 5/8" so the TPS tang fits the tang on the throttle shaft. Can't remember and didn't feel like disassembling. Easily done with aluminum spacers if need be...
