I want to replace my factory 6 disc changer to a smaller radio with an aux port cause I only use my phone for music. In the extra space I want to put a boost guage a pyrometer and a third that maybe you can suggest for me. I'm mainly going to be towing a fifth wheel camper so what else should I be monitoring? I already have a trans temp.

Back on topic: I want a radio mounting kit that will utilize the extra space for gauges do you know where I can purchase one?

You have a auxiliary trans temp gauge or are you talking the stock one? Because the stock one is absolutely worthless. Fuel pressure gauge is my vote.

I don't think you'll get enough extra space just from switching to a single DIN stereo. Now if you're ready to trim some plastic & do some custom molding, anything's possible.

like stated above. if you are willing to do custom fab/molding, check this link out. Couple gauges.. 7 to be exact - PowerStrokeNation : Ford Powerstroke Diesel Forum

if the trans temp gauge you have now is the one in the dash, I would install an aftermarket one, if you already have an aftermarket gauge then fuel pressure gauge gets my vote also

I do have a stock one, What do you mean by worthless? Are they off or just don't read hot when the trans is hot? Why would it be worthless?

This is awesome! I am defiantly thinking of this. I will have to check local junk yards for a dash!

Its not accurate at all, my last truck showed on the dash that my trans was fine but my autometer gauge was around 220 (about 80 degree outside) so it was getting pretty warm but the gauge in the dash didn't move

Mine read normal right up until my added gauge showed 300°(don't ask....clean your inter coolers).....didn't budge. I've got ####ty Glow Shift gauges. But I've had them measured for accuracy. It reads 10° hotter than actual trans sensor. Last truck had a pos trans gauge also.

The "gauge" in the dash is essentially an idiot light controlled by pcm. If temp is in spec it reads in the middle no matter how high in the spec it is. It won't jump up to caution area until its way to hot.
With my CTS I can monitor the actual temp. 40° of change in temp and gauge still shows right in the middle.
You can get different temp reading from an auxilary gauge because of the difference in locations of the sensors.

I used the scangauge 2 , installed below the single din radio and it worked great. had to do a little modifaction to the radio mount
