Vicfreg 772 Report post Posted November 30, 2017 My VHX gauge system is on the way. Any pictures/hints/lessons learned about wiring it up, where to locate and mount the interface box would be greatly appreciated. I will post my progress on my 1970 convertible project site once I get started. Quote Share this post Link to post Share on other sites
bryonbush 85 Report post Posted November 30, 2017 theres a good write up on mustang monthly floating around online. they put the box behind the gauge cluster on one of the flat spots. that's next on my list. Quote Share this post Link to post Share on other sites
2poniesngarage 4 Report post Posted November 30, 2017 I set mine on the sheetmetal that is above the radio seemed to be a great spot for it to me. Then I ran the adjustment controls over to the glove box because you have to be able to access them to calibrate the speedo. I had my wife take a car with cruise and then I was able to follow her on the highway and could set it that way. It was fairly easy. Setting the gas gauge was a pia. You have to be able to put 5 gals of gas in set that on 1/4, put 10 gals of gas in set that on 1/2 ,and then if I remeber right fill it up with 10 more and set that at full. So having 4 5 gal gas cans helped. But you do have to have the tank empty to start calibrating it.Now if you have A/C thats where the vents are so that spot wouldnt work. I dont so it was perfect.

Vicfreg 772 Report post Posted December 1, 2017 Thanks. I have A/C, so I think I am going to put the VHX box in the glove compartment. Appreciate the hint on the gas gauge, I will keep mine empty till I get ready to do the calibration.... Quote Share this post Link to post Share on other sites
