Speedhut Boost and Coolant Temp Gauge Install for 2003/2004 Ford Mustang Cobra with Speed of Sound A-Pillar Gauge Pod
First and foremost,
I would like to thank Brad, a.k.a. 03cobra#694 on SVTPerformance.com for giving me countless hours of input on my gauge install and on this write-up. Thank you LargeOrangeFont and Jimmysidecarr on SVTperformance.com for you input too. Props to Hunter, a.k.a. LTHL VNM on www.pfomustangs.com
I would also like to personally thank Alan @ www.speedofsoundllc.com for his excellent well-constructed gauge pod that matches the stock interior of the 2003/2004 Cobra perfectly…he definitely stands behind his product and is one of the few stand-up guys around that I have dealt with! Finally, I would like to thank www.speedhut.com, especially Aaron, for making the best looking/functioning gauges on the market…they truly look stock, and I get compliments everyday on the set-up. Aaron, also, truly stands behind his product!
I hope you all enjoy this write-up, and it helps ease the installation of your Speedhut gauges and SOS gauge pod…

1. Order your Speedhut Gauges from speedhut.com, they are the best looking gauges on the market
2. Order your Speed of Sound A-Pillar Gauge Pod from www.speedofsoundllc.com; it is the only pod on the market that matches the stock interior perfectly!
3. Buy two add-a-fuse MINI (1 for each gauge) from your local auto parts store, Bussmann is the brand I used
4. Disconnect (-) Terminal to battery
5. Take headlight knob off; IMO, the best way is to get a small right angle punch or pick and pull on the pin, visible when you turn the knob, while gently pulling on the knob
6. Take the two torx screws out right above the clear plastic cluster
7. Remove instrument cluster by removing 4 torx scews and disconnecting the 2 harnesses and disconnecting boost line…(you can find the boost line running from under the dash and disconnect the clip to give you more slack which eases removal from cluster)
8. Remove stock pillar; see video thanks to SOS (http://www.speedofsoundllc.com/i/Instructions/PillarInstall.wmv)
9. Dremel hole into dash right below the shown red arrow; this provides ample room to hide all of your gauge wires. Also remove 2 the two screws (in green) that hold the headlight switch so you will have more room in navigating the wires
10. Get you wire harness that came with your speedhut gauges…follow the simple directions…marry the smallest white lighting line to the larger white line, marry the smallest black ground line to the other larger black ground line
11. Using the above diagram from Speedhut, Marry the white line from each harness and connect it to the add-a-fuse. Pull the 5 amp fuse from fuse #37; insert the add-a-fuse into the spot where the original fuse was and put the original fuse in the add-a-fuse slot; now put a new 5 amp fuse in the other slot; Fuse #37 is for lighting/dimming
12. Marry the red line from each harness and connect it to the other add-a-fuse and pull the 15 amp fuse from fuse #5, replace the original fuse spot with the add-a-circuit and put original in slot of add-a-fuse…now put a new 10 amp fuse in the other slot of the add-a-circuit; Fuse #5 is for power
13. Slide wire harness leading with both input cables/sensors for the boost and temp sensor, be careful not to tear any of the wires on the metal near the dash…
14. Navigate the 2 add-a-fuses and ground line to the fuse box…mount ground on some metal (I chose to mount it on the fuse box screw/panel)
15. Navigate boost input cable to the glove box on passenger side
16. Open glovebox; pull the tabs inward and glovebox will fall open; Find boost line, remove yellow connector and insert T connector as shown, careful not to bend boost line
17. Connect rubber house from speedhut to the bottom of the T and connect to boost input cable as shown
18. Navigate coolant temp sensor cable to center console, then through shifter boot area(after you have removed shift knob, pulled back on plastic around shifter boot, disconnected cigarette lighter, and cut small hole into the rubber around shifter)
19. Protect coolant temp input cable with some high temp heat wrap and some wire loom and poke through your hole you made in the shifter boot area, patch hole around line with RTV high Temp silicone (I used 3/8 inch wire loom)
20. Navigate coolant temp input cable to from underneath the car forward toward the driver’s side block
21. Careful, Coolant may be hot! Remove 5/16 Brass Female Allen Head Bolt *Notice: some 03/04 Cobras have a simple regular bolt
22. Let coolant drain and insert Speedhut Temp probe into engine block (Use provided adapter from Speedhut or go to your local home improvement store and buy an adapter for the temp probe) Make sure to use Teflon Tape!
23. Plug up each gauge to each harness
24. Reconnect the (-) battery terminal
25. Turn power on: The gauges should turn on and the needle should move(Boost gauge should read 0 with power on); the gauges should light up as well. If not, something is not wired correctly or not connected
26. Disconnect (-) battery terminal again
27. Disconnect harness from gauge
28. Now, dremel the guage pod a little, if needed, to fit the wire harness connectors through pod hole (Careful, take your time)
29. Now secure all wires inside A-Pillar from Speed of Sound; I put both wire harness clips inside gauge pod to reduce the likelihood of the wires getting pinch when I installed the pillar…Notice, it may help to run one set of wires in the channel and the other to the left of the clip
30. Reinstall pillar
31. Reconnect (-) battery terminal
32. Refill coolant via Crossover tube burp plug
33. Admire your work, and thank yourself for buying the best looking pod and gauges for your TERMINATOR!
