Works great so far!
I bought this to allow my original speedometer to work in my LS swapped 1965 Ford Galaxie. I have it hooked to the vss and it is dead on accurate, have not tried the gps feature. Would definitely recommend to keep your dash looking original.

A great product.
This was what I needed to get my stock speedometer working in my 72 Monte Carlo with non- stock rear gears (4:11), trans (700R), and tire size.
For those who don't quite understand how this will work(like I was). Unplug your cable from the trans( find something to cap the trans). Reroute cable to somewhere water proof and plug it into the Jegs box. I removed my dash cover and mounted it on top of the glove box. Then run the antenna to a proper spot (mine is mounted under the dash cover right next to windshield.) Works great. Wish I bought it years ago instead of watching GPS on smart phone.

Worth it in my opinion
The price is kinda high, but someone put in the work and produced a quality product, used on an 86 Ford Ranger with a 302 with a 5 speed with only a speed sensor, it worked and would recommend to anybody!

I purchased this for a 71 chevy c10 with a 6.0 ls and 4l60 out of a cadillac escalade. I wanted the stock speedo to work. I wired per the directions using the gps antenna only and this product works fantastic.

GPS hookup was a breeze!
The first unit I purchased ended up being faulty, I called mega customer support and walked through my installation process, the tech helped me trouble shoot just to make sure I had done everything correctly (it’s three wires) once I walked him through everything (two seconds) he said easy send it back your unit is faulty. Got the new unit (due to storms it was snail mail). I hooked it back up to the wires previously run and bam I was cruising down the road with a working speedo. I installed this into a 1951 GMC that has a lS 5.3 and a 4L60e transmission, my gauges are original (professionally reconditioned) and I wanted to stick with them, this little unit let me do that. Also this thing makes no noise, I had a gearbox installed in another project (a different vendor and make) and that thing was louder than my M122 rock crusher tranny. I would highly recommend this to anyone who wants to maintain that stock look without after market gauges.
