Re: 67-72 Electric speedo

Hi Eric,
I am finally building my first electronic speedometer conversion cluster for a customer and have some questions for you.

First off, I wanted to let you know that I have found a way that works well that eliminates the speedometer mounting plate. Of course it requires some fabrication to the stock tin but in the end it will be all one piece. Not to take away anything you have done, just trying a different method.

Also my customer did not want a trip so that made my work a bit easier.

Now for my questions. I bought a gauge cluster for a 1996 S-10 from ebay. The high MPH on it is 100 MPH. Is this OK with the 120 stencil you provide? Will the speedometer actually work and be accurate over 100 MPH?

My other question was regarding testing the speedometer without a VSS signal. I have heard if you put power and ground to it, it will move to zero regardless of where the needle is positioned. Is this true?

I am trying to make sure I get this cluster built so that it will work for my customer. I may be able to find someone with a later model vehicle with VSS to test it on but I cannot say for sure at this time.

I will try to post some photos of my work soon. I had a camera mishap and don't care for my phone camera.

Hope you are well,

Take care,
Tom
