I recently did a 4r70w swap and all came out great I love it Question who has hooked up their cruise control to work after the swap please help. Also I connected the neutral safety switch but still turns on in any gear but then. Disconnected from switch car don't turn on any ideas? Thanks

The neutral safety switch may be bad, or is not switching when changing gears. It should close in P and N and open in other gears. Unplugging it suggests that you have it wired in properly. Connect an ohmmeter across the pins with it unplugged, and see what it does in the other gears.

I have my cruise control hooked up and working. I'm using a manual PCM instead of an auto pcm, and had to add a wire to the PCM for grounding the clutch signal, I think. Brake pedal still disengages cruise as normally it would.

How much HP are you looking to push through the setup?

I will check the micro switch then maybe bad like you said and I'm using an auto computer

Congrats on your new PB! On my 2005 the neutral safety wires are RD/LB and WH/PK and can be found at the bec or the oem tranny harness by the shift position selector. Although I'm pretty sure your 2007 will be a little different. The cruise doesn't work on my 4r swap, but I don't really care to fix it LOL.
