Re: 67-72 Electric speedo

Alright, finally have an update on mine. I changed some things around. Instead of running a separate light for the check eninge light I used the temp light location in the gas gage by cutting out the filter of the s10. Also swap the brake warning filter. After the initial start the 60lbs oil gauge was pegging so swapped a 80lbs gauge in.
Here is the big kicker. I'm not sure I'll be able to run this set up in my truck because the speedo reads 10x of what it should. I'm running a 2008 genIV ecm and tcm with a 4l60e. Does anyone know if the speedo pulse output can be changed in a tune?
