I have an older 3780 tach that I need to modify the wiring to mate with my factory harness. What gauge wire does this tach use? I can count the # of strands in each wire, but I do not have a micrometer to measure the diameter of the individual strands.Thank you for your question. The 3780 Tach has 20 gauge wire leads coming off the back.Date published: 2019-04-02
Hi, do you supply replacement bezels as I have damaged mine. Uk customer.Hi Bugman, thank you for the question. Since the bezels are actually machine pressed on, we do not offer them separately as an accessory or service item. We can replace a damaged bezel, but it would have to come into our factory in the U.S. for that service.Date published: 2018-10-16

Is the tach waterproof? Want to mount outside on the hood of a 1972 roadrunner...if not do you sell any that are thanks!Hi Mikey, thank you for the question. We actually do not offer any completely waterproof tachometers. We offer a several Pro-Cycle and Marine tachometers that are water resistant on the front only, but nothing that would be recommended for outside hood mounting that would be exposed to the elements.Date published: 2018-08-15

are these water or I should say weather proof ? going on a hood of a expedition suv.Thank you so much for contacting us. Unfortunately, while this tach is built to be incredibly durable, it is not weather sealed and only recommended for use inside a vehicle. All of our automotive tachs are designed this way. If you want to put a tach on the hood, we could special build you one of our Pro Cycle tachs (which are weather sealed) calibrated for the V8 in your Expedition. Here's a link to check out: https://www.autometer.com/gauges/pro-cycle.html#1&profile=products If you'd like to proceed with one like that, please give our team a call at 866.248.6356 and we can walk you through the process. We are open M-F, 8am - 5pm CST. Hope this helps!Date published: 2018-01-04
