GPS Speedometer Install
-
The GPS speedometer arrived today so I figured I might as well play around with it. I had a trashed instrument cluster that I could experiment with so I started the modifications on it. The first picture shows the components of the kit. The second shows the lens mod. I cut the hole with a pair of dividers by going in a circle until it cut through the plastic. You might be able to use a hole saw but it would have to be turning very slow and probably need to be cooled with water. Third the tin mod I did with a hole saw in a drill press. You have to go very slow with this too and wear gloves. If it catches it will probably ruin the tin. I let one end of the tin rest against the drill press post as a stop. The fourth picture shows the speedo installed in the tach hole. I didn't have to modify the bezel for the 3 3/8" speedo. As seen in pictures 5 & 6 I soldered the black and white wires from the power inverter to the main power harness wires and used heat shrink tubing on them. This just saves running two more wires out the back of the instrument panel. Picture 7 shows the plug in connector I installed in the constant power wire so all three wires from the speedo can be unplugged. That way the retainer can be unscrewed and removed to get the speedo out of the cluster. Picture 8 shows the connections to the fuse block on my '67 and picture 9 shows the antenna connection on the back of the speedo. The cable is 15 feet long and the block on the end has a really strong magnet in it. Don't get it too close to your Digital camera or your cell phone 'cause it will probably erase the stuff on them… I bought the white face one because I'm going to order the white decal kit. The last picture is with the speedo set in the stock hole. If a person was going to do this I think the 4" one would look better although it does match the size of the fuel gauge. If it had a black face it would look better too. Hopefully I will be able to get it put in the truck in the next couple of days but I'm going to a swap meet tomorrow so it probably wont happen then. I will be adding to this when I get it in… LockDoc

Re: GPS Speedometer Install
Oh man that's cool! How does it work, do you have to program or subscribe or anything?

No subscription. Just use it. Works like a GPS. It has odometer, trip meter, clock, elevation, speed, compass, top speed, 0-60 time, and 1/4 mile ET. LockDoc

Re: GPS Speedometer Install
Way to go LocKDoc.
Only draw back now is if Obama wants to know where LockDoc is, and how fast he's driving that BB, and what direction thru the corn Fields in Iowa, he can find out if it's safe to steal a sample of that outstanding homemade brewed wine.

Re: GPS Speedometer Install
LockDoc,
It looks great. Nice neat install. I know it's early in the am, but it looked like you were installing it in the tach hole and the last pic shows it in the speedo spot. What am I missing? If you don't mind me asking, what does something like that run?

Re: GPS Speedometer Install

Installed the temporary instrument cluster with the GPS speedo in it this evening. No problems hooking everything up and it seems to work great... The light is nice and bright and it is easy to read. I will take the Garmin along in the morning to check the accuracy. I put 7 miles on it tonight. LockDoc

Nice look to it. I wonder how it will work in a city envoriment though? I may have to do a whole cluster for my 71. I'm tired of the speedo being off and bouncing all over the place at slow speeds.

Re: GPS Speedometer Install
Hopefully when the time comes I can afford one of these, nice job/write up. I also found a bunch of these as apps for mobile phones, I thought they were neat anyway: http://www.ranosoft.net/palm/speedometer-gps/
But, I think once all is said and done, I will be getting the correct change over speedo gear for the trans (rear gear/tire size adjusted). As this is the most affordable/functioning option for me. The added functionality of those gps speedos is pretty handy, wish I could get one.. like I said.. hopefully. Again, nice work! |

Re: GPS Speedometer Install

Well I put the Garmin in the truck and went for a little drive. The GPS speedo was spot on. I know they get the signal from the same satellite but I wondered about the conversion from digital to the analog output. Also no problem with the crappy, rainy, drizzly, foggy, overcast conditions we had today. LockDoc

Re: GPS Speedometer Install
I noticed that some of the Speedhut GPS units had high beam and turn signals built in. That would be real handy for a clean custom dash.

Just called Speedhut and found out they have a 4 1/2" speedo to!
Also when you order there other gauges they come with everything you need to make them work. Cool! I have to get my Christmas list done now! Just what the Doc ordered!!! ![]() ![]()
