In February 2016, I made time to install a Boss 302 Laguna Seca Gauge Pack in my 2012 Kona Blue Boss 302. I thought about this for some time and I finally decided to spend the extra money and purchase the Ford Racing LS Gauge Pack Part Number M*6304GPACK-MA. Since I would have to cut my OEM dash pad, this is one Boss 302 modification that would stay with my car and hopefully add value some day.
Another option would have been to purchase the LS gauge pod, ($89. USD) and install AutoMeter guages for Oil Pressure, Oil Temp and Coolant Temp, but in the end, I wanted to keep the look of installed gauges Factory. Another consideration was ease of installation, this kit comes with a very nice OEM wiring harness loom, and to me, this feature is worth the additional price of the Ford Racing Kit. During installation, it is very easy to follow the OEM wiring harness with the new supplied gauge harness and everything matchs the OEM underdash wiring loom. Even an under dash inspection would show nothing out of place and everything as tidy as it would come from the Flat Rock Mod Shop, the final assembly point of our Boss 302 Mustangs.
Ok with that said please keep in mind as you review this thread that I am not a technician by trade, however I do have an excellent mechanical aptitude and I like to work on my Boss 302. I try to keep a clean car and I enjoy driving it too. As you can see in the background of the pic below, there are a few more Boss mod parts for 2016.
We'll start with "Whats in the Box". The gauge pack comes pre-assembled:
Includes a little sun screen bonnet:
This is the back side and visible through the windshield: Note: There is a marr, or a mark on the back of the gauge pod. I was not happy to see this mark as this kit happens to be the second FRPP Gauge Pack Kit i received. The first kit had a few missing parts and had the same marr or marks in the same location. Once it's installed, it is not noticable through the windshield, so I kept it as is. Quality Control is not what it should be.
The business end of the gauge pod: Note: In this picture, (Below) the gauge pack wiring harness is tucked in side the pod, it is shipped this way and it also allows you to test fit the dash mounting bracket and to test the location placement on your dash pad, as the gauge pack will sit flush on the top of the dash.
The wiring harness:
Oil sending unit, screws, clips, connector and mounting bracket:
First, I test fit the base into the gauge pod, and due to production changes to the pod, mounting the center e-gauge accel tube with metal clips, this prevented the gauge pod from sitting down flush with the mounting bracket and it would not "Clip" into place. Looking at the above pic, you can see the mounting bracket has a raised section with a rectangle hole. This is the hole that receives the metal spring clip that you install on a plastic tab in the gauge pack housing. See below:
As you can see above the spring clip is now "Snapped" into place, (Note: The next 2 pictures deal with a slight modification required to allow the spring clip to "Snap" in place.)
Looking at the 2 pics posted below, I had to modify the inner side of the pod to make this happen buy cutting "U" shapped grooves to reclip the e-gauge instrument tube, (This tube as seen in the second picture show below, is actually a part of the e-gauge insturmentation, it is a sensor). This tube sensor must be mounted by 2 plastic covered spring clips to the interior of the gauge pack housing. It must be mounted level to the housing.
The picture will show you how I had to cut 2 "U" shaped slots to remount the sensor tube. This gave the mounting base enough room to sit deeper in the housing to allow the spring clip to fully engage, or Snap in place. The result of this gives the mounted gauge pack housing secure attachment points at both the front and rear of the dash mount.
Just below is the U slot cut to proper depth and i have used a small exacto knife saw blade to cut the right side U slot. I then used a exacto knife razor attachment to trim the slot to the proper depth. Extreme care must be taken to not Break the plastic rail when cutting the U slots.
What a shame to have to do this, Right? Especially when one considers the price of this Boss 302 LS "Official Ford Racing" accessory.
Above: Now you can see the interior gauge pack wiring harness sensor tube is clipped back in place, this time it sets deep enough in the housing to allow the mounting bracket to fully engage the mounting clip, which is also user installed. Again, this sensor tube must be mounted level for proper operation of the g-force movement feature of the e-gauge as displayed when vehicle is in motion.
Looking below we can see the end result of modifing the harness attachment points. The mouting bracket is fully seated to the housing.
