Hi
Would like to know if this can be done using the OEM wiring that is connected to the RPD?
From what I dug up, the gauge is a 4 wire connector as the RPD looks like 6.
I understand disconnecting the RPD will not let the car start and did find how to jump out the terminals if you just want to remove the RPD.
Thanks

Why remove RPD?

Would like just a gauge on the A pillar instead of the RPD.

Easiest way would be to wire in a real boost gauge. I doubt anyone has ditched the rpd for the regular gauge.

Basically, you need to bridge pin A to E, and B to F

The "analogue" boost gauge is signaled electrically too but not off the GMLAN bus. You have 3 options (listed in order of increasing difficulty):

1. Find out where the 2008 cars pull their signal from and hope that your car has the same line as well. The signal should be coming from the ECM. I suspect that this signal exists on all of the LNFs as the 09's came with either an RPD or an analogue gauge.

2. Get a mechanical boost gauge along with a T fitting. Tap into a pressurized line.

3. Create a signal converter that takes the boost signal from the CAN bus and transforms it into a signal compatible with the analogue gauge.

EDIT: I found this in my documents archive. No guarantees that its right so proceed at your own risk. Exercise due diligence, and probe it with a oscilloscope if you're unsure.

I would like to switch my boost gauge for an rpd. Is there a connector there that i can hook up to or is it a different harness?

Its been done before. Search for the thread

You really want to remove the RPD? Even when it's dusk and I can barely ready the muthafukr I wouldn't want the stock boost gauge
