Gauge upgrade

[scubadog]

I have repowered from 1987 200 hps to 2005 hps HPDI's. I have twin engines. I need to change my gauges I am being told to purchase 6YR-W0035-E2-00 for a tach kit and 6YR-W0035-F2-00 for a tach. and speedo kit. Do these seem to be the correct gauges? I am told all the wiring harnesses needed for install are in these kits. Is that correct? Thank you.

Yes they include the wiring.

Thanks for your help. So the gauges I listed above are the correct ones to use for these engines. Will I have any issues with the existing wiring harness that is 1987 era or will the harnesses that come with the gauges be all I need?

Those gauge kits is all you need on 2005 and newer motors.
