I bought this truck a couple years ago the tach has never worked. This truck originally had the 2L-T and the previous owner had put in a 3L from a Hilux and kept the turbo from the 2L-T. The 3L has a mechanical injection pump but I’m not sure the generation or what year hilux it came out of,and I’m not sure what sensor I could use to try and hook up to the original tach. I feel like the people that did that swap didn’t feel like going the extra mile and have the tach work in the dash or it might be a big pain in the a$$ to get working. If it’s too complicated I’ll just throw in an after market tach and be done with it. Any comments or recommendations would be appreciated here’s the plate inside the engine bay if that helps.
