PET tach install ?
If anyone has directions on how to install a PET tach on a 4-tech I would greatly appreciate it.
I will be working on dialing in a friends boat but it doesnt have a tach, however he does have a PET tach that was hooked up at 1 time so before I pull my hair out trying to figure it out I thought I would see if any of you know how to hook it up.

When I ran one I ended u psetting it up as a 3 cylinder 4 stroke and wrapping the pickup around the front coil. I actually had to run the tip of the pickup just into the area where the coil clamps down on the plug to get it to pick up correctly....I tried all 3 cylinders and had the same results.....
I set it up as a single cylinder 4 stroke and it worked fine. I could never figure a way to wire it in to read all 3 coils. I guess with a longer wire but it seemed kind of pointless....On only one coil it read the same on all three cylinders and was always withing 20ish r's of the stock tach (I have a 04 that reads in 50 rpms increments).....
