12589161 OS change from DBW to DBC - Which BIN?

[tjones018]

Hello Everyone,

I'm helping my neighbor with an LS swap. 2005 Express Van 3500 6.0/4L80e into a an 84 C10 pick up. I've done a few LS swaps, but always used an Aftermarket ECU

Not doing anything wild with the engine - Stock long block - TBSS intake and Headers.

The van that we pulled this out of had Stabilitrack and was DBW. PCM is HDW No. 12589161 Serv. No. 12589462.

I have read that this PCM is one that can do DBW but also has IAC drivers installed.

Which BIN would I need to convert this to DBC? I assume that any "Blue Green" conversion harness would work.

Is it as simple as doing a full write of the bin with PCM hammer with the new BIN and then deleting VATS?

Thank you for your help.

You will need the correct Blue Green harness with the TPS and IAC connectors. I would probably use a 12587603 OS that has a 4L80E transmission segment. You can go into the options matrix and change DBW to DBC.
