I’m currently looking at options for re-incorporating a functioning tachometer on my 7.3IDI. I was originally entertaining aftermarket kits, but it seems like Craigslist is having a dash parts Renaissance at the moment. Being a gas-to-Diesel swap, my truck is currently equipped with a 5k tach. I’ve seen a few diesel tachs for around $50 and sensors for $80. From what I understand, most instrument panels are plug-and-play as far as swapping OEM gauges are concerned. So that begs the question, will plugging in a 4K tach work? I’m not sure if the wiring harness is an issue, or if it is even economically intelligent to return to a factory tach setup seeing its affinity for not working.
I’ve spent some time in the tech articles, but there is no mention of gas/diesel gauge interchanges. Of those threads detailing aftermarket tachs, all of the posts are fairly old and provide part links that are either dead or have greatly increased in price. I would hope that there would be cheaper tach alternatives, but so far, all my google-fu has taught me is that I need to acquire some Daddy’s Money™ if I want to know my RPMS.
