Re: 67-72 Electric speedo
I can't say for certain but I think you would need to run the speedo signal thru a ECM and then a DRAC module and then to the electronic speedo.
If you don't get the answer you are looking for here, contact a moderator and have this post moved to 'Engine and Drivetrain' Quote:

Re: 67-72 Electric speedo
That doesn't mean you can't use an ECM and DRAC to operate the speedo. You can pickup a ECM and DRAC cheap at a wrecking yard. If that just isn't an option, check with Dakota Digital. They have a electronic speedo unit, but I don't know the details on it.

Re: 67-72 Electric speedo
Hey Eric
I cant seem to find the testors paint colors by the 180 101/180 111 codes. Are there other numbers that are on the bottle? Can you post them if you have them? Ive also seem guys use krylon seafoam green for the inner tin. Would you happen to know if thats a close match for the lens numbers? taking forever, and nowhere near as nice as these, but its fun ![]() thanks man!! |

Re: 67-72 Electric speedo
So I have a question for ls1nova71 about modifying the original speedo faceplate. I understand that the original odometer hole in the faceplate needs to be widened to accommodate the extra digit of the new odometer, but when the old faceplate is centered over the new speedo assembly the odometer hole looks to be too high, as if the hole needs to be moved down just a bit. Was this something you had to do during your conversion, or is there another method to avoid that?

Re: 67-72 Electric speedo
Hey BigRed
Im not Eric/ls1nova, but ill try to help. im doing the swap, and you dont reuse the old metal speedo face. you mount the new decal over the cutout plastic s10 speedo lens and align the s10 speedo lens with the fuel gauge in the right hole of the cluster does that help? |

Re: 67-72 Electric speedo
Looks like jks67ss396 got you squared away (thanks btw), I tried using the metal face, but asyou found out, it just doesn't quite work as well as the s10 face.

Re: 67-72 Electric speedo
Ls1nova71,
I'm using an s10 electric speedo with one of your face decals. I'm also using the exact same LED hi beam indicator but green as you. It steadily turns on and off in a flickering manner. Did you have any issues? Did you ground everything to the tin and then ground the tin like I did? Do you or any one else know what the issue could be? It seems ground related or a bad diode or resistor. |

Re: 67-72 Electric speedo
I did ground everything to the tin and then another ground from the tin to the harness to a good ground under the dash, and have never seen the problem you are describing. Have you tried taking it out and hooking it directly to a battery and see what it does?

Re: 67-72 Electric speedo
Has anyone found a paint that is the correct color for painting the new speedo numbers? I know ls1nova71 said he was just mixing paint to make the correct color, I'm just wondering if there's a premade color that will work...

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

I appreciate the information. I will get some photos posted when I get time and the camera working. I am also working on making a wiring harness that I think will work nice. I have limited time to work on this so my progress is slow. Stay tuned... Thanks again, Tom

My electric speedo cluster is still in the works but I went the route of modifying the tin to eliminate the plate like you mentioned you were doing for a customer.
