Speedometer cable location?

[Rattee]

I’m looking for suggestions on how to run the speedometer cable for my turbo 350.

Buy a GPS one. Just a few wire hookup.

I ran a cable from the trans under the body and up through the floor board just behind the firewall and hid it under the carpet that goes up the firewall. I have a cable setup in two cars, it works, but depending on tire size, gear ratio and whatever I have forgotten you may have to change the transmission speedometer drive gear and the cable driven gear. None of this is hard but maybe time consuming. GPS units are probably much simpler. I have no experience with them so I don't know how accurate they are. In reality you don't really need a speedo, the nice policeman will tell you how fast you were going.

I have a GPS Speedo in my bucket. It works hood. I had to replace the first one I bought as it failed. Don’t buy a cheap one. Easy hookup. 3 wires, pos, neg and light. They you screw in the antenna cable. You’re done.

I have a GPS spedo from Speedhut, but you could also use the tach once you get into high ghear.

For some reason the forum was not letting me see your response. I’m not really looking to go with gps due to the fact I already have gauges. What length cable did you use .

I did those more than 10 years ago, and can't remember the length. Actually I might not remember if it had been last week. Nevertheless, one idea is to run a piece of wire along the path you wish to take and then pull the wire out and measure its length.

Just a FYI, I looked into their gauges when shopping for mine and yes, they are assembled in USA, but the components are not manufactured here, not all of them anyways. I’m sure they are fine but at the price point, I was less than enchanted by this fact. Sadly, in our global economy, few things are actually manufactured here anymore.

You can get universal cables that you cut to length.

Looks like we didn't directly answer your question, except for 409T. I tried using the cable for my TH 350, and ran it thru the top of the transmission hump and back to the cable entry port. Gearing was wrong and I drove for awhile with an RPM/MPH conversion chart taped to the dash. Finally went the GPS route and am a happy camper. Works flawlessly and gives me the correct speed reading at all RPMs.
