Shifter Boot Bezel

While the truck was in the paint shop, I decided to try and tackle the issue of the shifter boot.  The shifter in a stock S10 is much larger than the Hurst shifter used with a T56 and the boot would not look/fit right.  I wanted it look good, so I tried to come up with a simple, but elegant solution.

The pictures below are of the factory boot in the console.  The main problem is that it is a molded rubber and cannot easily be replicated in leather without a big headache.  Actually, I was told that it could not be done and look good.



I had just done some recent work on a BMW I own and I noticed that BMW uses a plastic bezel to hold the boot in place and that gave me an idea.  Why don't I make my own bezel?  Here is what I came up with.

I started out using a piece of paper and tracing out the hole on the console and taking some measurements.  The first thing I noticed was that the hole is not symmetrical.


I then downloaded Sketchup and began a new design.  I copied the measurements and printed out a 2D version of my trace. 


 I glued the printout onto some foam board and began some fine tuning/trimming.



After several iterations or modifying, printing, gluing, and trimming, I felt like I had a good template. I went to work in Sketchup to hammer out the 3D design.  The below pictures are some of the stages I went through.

When I was finally happy with the look in SketchUp, I uploaded the design to Shapeways to get it 3D printed.



I got it back and it looked like the pictures below...sorry for the bad quality.  I didn't have good lighting here.



I spoke with an old friend (Chris at International Auto Upholstery in Sarasota) and he made the actual boot and attached it to the bezel. It came out awesome.



You can see how the leather is glued to the bezel in this photo



I had to do some slight trimming of the corners of the console to accommodate the "bunching" of the leather where it was sewn.  Here is the finished product. I think I spent a total of about $200 including the price of Shapeways, the upholstery shop, and the cost of the leather.



 Bonus, I had some leather left over so I had Chris cover the console lid.  That was about another $100.  So, for about $300, I have a pretty cool console now.

DBW issues

After getting the truck back from the body shop, I started hooking things up and I noticed that I have a Drive By Wire issue.  The throttle blade was not moving when the pedal was pressed and it was throwing a P2128 code (P2128 - Throttle/Pedal Position Sensor/Switch E Circuit High Input).

I contacted the folks at Current Performance Wiring (the people that I bought the harness, computer, and pedal from and they nicely sent me a new Trailblazer SS (TBSS) pedal, stating that the corvette pedal I had would not work.

I hooked up the new pedal and no joy.  Actually, it started throwing more codes (P2138 - Throttle/Pedal Position Sensor/Switch D/E Voltage Correlation).  I asked for a pinout diagram and they emailed one to me:



This matched the pinout on the connector.  I checked for continuity to the main harness (in case a connector was loose) and all was well.

I also ensured that the connections to the ECU where correct per instructions:
here is where each one of the pins go to in the computer C1 connector

A- tan   pin 35
B-LtBlue pin 49
C- purple pin 37
D- Brown pin 36
E-Dark Blue pin  47
F-white/black  pin   33

I this point I pulled out the corvette pedal and looked for part numbers.  I found one:  25835421.  The pedal is for a 2005-13 C6.  I needed to find the diagram for the Accelerator Pedal Position (APP) sensor to see if that matched up.  I found one:


This diagram told me that I needed to swap the Tan wire (position A) with the Purple Wire (position C).

Below is the harness after I remove the wires from their original position.


Below is the harness after I moved the wires to their new position.

I hooked up the pedal, turned the key, and I can hear the throttle blade move when I press on the pedal.  I haven't hooked the computer up yet, but I have a good feeling.

Couple of bonus photos...
