1227747 to 16197427 Conversion PCM Swap with Wiring Pinout Directions!

so does anyone know the pin in the 427 for the power steering pressure switch?

What bin would you start with on 350 and th400 trans and 4-11 gears when doing this swap. yep just bought a 427.

I have been looking for it for about a half hour now, I can tell you the PCM sees the input at IAC Mode Word #2, L4E86 bit 1.

"Fast355

I found the info about PSPS on Chilton's, page 6-60, 2.2L > F8

I've always been skeptical of that answer, since that pin is used with 4wd, so I just order a 1994 GM service manual. Should have a answer in a couple weeks.

AAHHHH. I would test it if I had a way. What does the switch put through on this wire?

I don't know but I have one that works and shows when in use in adx on my LT1.

Got the new book in today, and F8 is the correct pin for the power steering switch. Also, fount out that B1 is for the DIS system used with the 2.2L. It is called the 1X Signal, and is used for ASDF (Alternate Synchronous Double Fire).

Anyone ever find the VATS pin? I'll trade you the AC High Pressure Switch pin. This was used to raise the idle if the A/C pressure got too high (no bins that I know of with this active).

Might try this, and just uncheck TCC only. But you would need to set up something for the kickdown. I think dave w had something figured out in the .bin to use a PCM output to kickdown. Try a search.
